Germán efficiency with boarding; not superfriendly, but appropriate; they were also mask Nazis with wearing you mask even if it had fallen below your nose while sleeping

I'm not really sure what the difference is between Economy and Premium Economy on these long-haul flights, especially when the plan isn't very full and people in Economy can lie down across an entire row. The seats in Premium Economy are a bit bigger, but you can't recline or lie down and I'm pretty sure we get the same food options as regular economy. You get a little goodie bag that you don't really need. Also, there is really no point upgrading to business class on the short flights with Lufthansa. The seat size is the same as the rest of the plane. So, you're paying $50 or so for a pretty small snack/meal and a curtain between you.

Pros: "I like the notice given prior before I get to the airport on regard to a free carry-on check in. The staff was friendly and enthusiastic happy giving me the comfort of a nice travel journey. Thank you to all the staff!!!"
Cons: "Honestly nothing I was really happy with my flight!!!"
Pros: "Great crew, decent food, plenty of wine and other drinks, on-time departure and arrival."
Cons: "Cramped uncomfortable seating, USB port on seat-back video display does not charge a handheld device battery."
Pros: "Everything"
Cons: "Nothing"
Cons: "Again, there was not enough time between flights. It was a HUGE rush in Denver to get to my next flight, and I almost missed it."
Pros: "They were smiling and very welcoming"
Pros: "Great crew. Great seats"
Cons: "Flight was delayed by half an hour. Mainly due to limited carryon space. During check in we offered to check in carry on luggage, but were told it would be an additional cost! If they would have checked it in that would have saved 15 minutes easily"
Cons: "Awful layover in Frankfurt. The airport alone is the size of a small city with checkpoints everywhere. Was simply exhausting flying through Frankfurt."
Cons: "The plane was uncomfortable and things were falling apart"
Pros: "Very friendly and accommodating"
Cons: "NA"
Pros: "Very nice flight, the food was super delicious and the crew very professional"
Cons: "N/A"
Pros: "One flight attendant in particular was outstanding, Eva. Because of her, I would definitely consider Lufthansa for our next trip to Europe!! She mot definitely went above and beyond in her service and professionalism."
Pros: "Seats, crew"
Pros: "The service on board was excellent."
Cons: "Boarding got a little bit chaotic for families with small children."
Pros: "Breakfast food was fantastic. Staff was helpful, anticipatory, and thoughtfully accommodating."
Cons: "No access to usb power outlets."
Pros: "Was not allowed on flight"
Cons: "When I missed the connection from the first leg of my flight and purchased the ticket from that leg to finish my itinerary, Lufthansa cancelled ALL of my return tickets. Both Lufthansa and my travel agency pointed the finger at the other and I had to purchase another $1000 ticket to get home. There was no cancellation emails or any notification. I didn’t know my tixkets were cancelled until I was trying to check in. Worst experience ever!!"
Pros: "One airhostess ruined my flight experience. Anyway in the beginning on the journey my daughter was not well and other crew members gave her candies. I liked the sweet gesture."
Cons: "I was traveling with my daughter. There was no food choice left for my child and me. Crew member rudely said there is only beef option left do you want to have it? I said no. I asked her are we not going to get anything to eat since you are out of options. She continuously kept on repeating that I said no and that she kept emphasizing that there is only beef option left. Finally she save the supplement To meal. Her tone was very impolite when especially we pay so much and service we get for a long flight is good"
Pros: "We were late on arrival due to a delay in our connecting flight. Lufthansa had a courtesy van waiting for us on the tarmac and ushered us directly to the flight being sure we did not miss our flight. Lufthansa went above and beyond in their customer service!! We are truly grateful to the airline for their assistance and superior service!!"
Pros: "Great flight crew, inflight entertainment and food"
Cons: "Damaged bag...working with airline to get replacement"
Pros: "On time flight with no problems"
Cons: "Uncomfortable seats so hard to sleep during flight"
Cons: "The seats are too close. When reclined it's not possible to get out."
Pros: "Crew was great. The frequent offer of water on a long flight was appreciated. The flight was on one, smooth and pleasant."
Cons: "Meat in the casserole ( goulash?) was not chewable. Other meals were fine."
Pros: "Service was excellent. Boarding fast and efficient, but would be better if the grouped."
Cons: "I am only 6 ft but knees hit the seat in front. Tray table hits my stomach even without the recline on front seat. Woman across aisle from me couldn't get out of her seat when the person in front reclined. This should just be illegal, period! Food was not very good. Entertainment options was limited."
Pros: "Exceptionally clean gate area and aircraft. Professional and friendly gate crew as well as flight crew. Well treated as a passenger. Genuine."
Cons: "Nothing noted..."
Pros: "Everything was great and deserves excellent in all categories."
Pros: "Kayak had good e emails with updates and reminders. Lufthansa was a great suorline for its care of its passengers."
Pros: "online booking"
Cons: "There is no one at Kayak to answer questions on weekends. Message says "call back during 'regular' business hours" but does not specify what that means, nor what time zone they are in. (BTW, most people travel on weekends so ya may want to consider providing customer service then...duh). When I finally was able to reach someone in order to upgrage to Premium Economy, they could not help me but said they would send an email with an answer to how much that would cost. The email never came. I will never book with Kayak again."
Pros: "All airplane was on time"
Pros: "Lufthansa always impresses with good food featuring more local ingredients (sauerkraut and mache when leaving Europe), loads of in-flight entertainment included in the ticket price and a very speedy boarding process, even when dealing with United States security requirements. I always like beer and wine being offered at meals as part of the flight price, as well as the aperitif option too."
Cons: "There were a few flight crew this time that disappointed by being less than professional and less than present, knocking serving carts into chairs, being curt in their service and less polite than usual. I noticed two flight attendants in particular this time when normally the entire flight crew is very professional, courteous and timely. Flight was also late leaving Munich (computer issues) which made connecting flights in Denver difficult."
Pros: "Good was yummy and the setwardess were super friendly. Staff was plentiful and the plan was very modern and high tech. Also had a layover in Munich airport and it was amazing. Very high tech, I took advantage of the napcaps and shower facilities. Also the restaurants were on par with great red win."
Cons: "The flight was 11 hours.... can you make that a little quicker next time, I mean come on it's 2017...."
Pros: "They fed us well, and the food was surprisingly good. Feather pillows were a nice touch, and great variety of movies to choose from on the long flight."
Pros: "I loved the TVs, food, and the service. The TV's had so much to watch, and made the time pass so much faster. The service was amazing! They came by so often to give us whatever we needed! Great experience!"
Cons: "Nothing"
Pros: "Best part: Getting off the plane and swearing never to fly with Lufthansa again."
Cons: "Flying to Munich- flight was cancelled. Had to rebook on United for the following day. Arrived almost 2 days late (the original was direct, the United had layovers) and missed a planned trip to Neuschwanstein castle. Flying from Munich- The entertainment screen was broken, completely unusable. After a hard reset by the flight attendant several times... Still broken. She said she thought it would fix itself once we were at cruising altitude. Nope. Notified the flight attendant who said vaguely "I'll see what I can do..." Never came back to check, never got offered any sort of compensation (even something like a free mixed drink would have been nice), offer to move seats, nothing. So- ten hours with no entertainment/nothing to watch, just a malfunctioning screen. Food was mediocre. We boarded late, and left almost 1 hour late because they had to wait for an employee (who was not working, just getting a ride back) to board. Literally there and back with Lufthansa was a fiasco. On top of it, we have been back for 3 weeks and are still waiting to hear back from Lufthansa customer service. Apparently they only communicate by email with complaints. Not over the phone. So after repeated emails, just radio silence. Terrible airline."
Pros: "The staff was so accommodating and friendly! Great trip!"
Cons: "Nothing."
Pros: "Good food, friendly flight attendants"
Cons: "Boarding process was torture. Lufthansa invited us to check-in early, but would not allow us to finish the check-in online process the day prior: seemed to be glitch in their computer system. We arrived at the airport early, but no one at Lufthansa could help us with seat assignments in order to seat our 12-yo daughter next to a partent. The airline did not open the gate area until 1+35 prior to the flight (advertised 2-hrs prior), and did not put anyone at the gate-desk until 1-hr prior to departure ...and they still could not help us. Boarding was disorganized; Lufthansa appeared to board by different groups, but there were no announcements as to which group(s) should board. Instead there was just a large crowd milling about, waiting to push their way to a gate agent. Very un-German."
Pros: "Lufthansa is by far the best airline. All crew members were very friendly and attentive. Food was also great."
Pros: "great food ,service"
Pros: "I have a servere hearing problem and was concerned (since we were late leaving Zurich for my changeover in Frankfurt), that I would be late because I can't hear any loudspeaker systems (either on planes or in airports). I felt that I could get easily lost between flights and not have time to get to the Frankfurt/Denver flight. I told this to the person at the gate in Zurich, and he immediately arranged for someone to meet me in Frankfurt and take me there. I was met by Maika in Frankfurt and she was just excellent--personable and efficient and really helpful. I'm sorry I couldn't remember the name of the person at the gate in Zurich. He was also great. I wouldn't have done this if I had had more time, but this really made my day (and my flight!) ! Thank you!"
Pros: "Everything"
Cons: "Nothing"
Cons: "Seated near and next to me were about 9 German men who had begun their vacation to Colorado in the airport bar prior to the flight. I was seated in a middle seat "J" (I believe) in row 37 or 39. The men were receiving from the stewardesses repeatedly two glasses at a time and kept going back to the galley and getting two glasses of wine at a time Although they were loud, congregating in the aisle around rows 37 and 39 they were not limited in what they could drink. The two on either side of me were disrespectful of my personal space and were very inappropriate. I got up and went to the galley behind my seat to ask the stewardesses to get me another seat. During this time the guys kept coming back to this galley for more wine still taking two at a time. The stewardesses explained that the plane was full. Others complained also. I then asked the stewardesses if since they were over serving these guys, would they trade one of their jump seats with me. At this point they cut the guys off and got the pursar. She talked to them and ignored my personal safety concerns and said no one gets on a plane drunk (yeah, right) and that they would now behave and were asleep. That's why they are still talking at the top of their lungs and standing in the aisle? I asked. I wish I had video recorded this, I did not as others with kids in the aisles across from me did. I hope their videos go viral Not impressed with Lufthansa"
Cons: "Reserved seats, and the switched them. Had horrible seats."
Pros: "Everything was wonderful. I'll definitely choose Lufthansa again!"
Pros: "They know what they're doing!!"
Cons: "No complaints at all!"
Pros: "Excellent service all around"
Cons: "They don't board with any structure. It is a big free for all."
Cons: "I did not like the bathroom downstairs."
Cons: "The seating was poor. The armrest did not go up even so I and another passenger tried hard. I then had to climb over it to be able to get to the washroom at 86 that was not the easiest and again it should not happen regardless. Otherwise I was treated well.I was a wheel chair passenger for medical reason. Thanks Helen"
Pros: "Without the help of the attendants at the gate waiting to take us to the connecting flight, we would not have made it! So grateful for their help! Food was very good for airplane food and movie choices were excellent."
Cons: "Seats were quite uncomfortable due to inadequate leg room."
Pros: "Best flying experience ever. Loved the new aircraft. Crew was exceptional. Service (food, drinks) was wonderful. Loved the continuous water offered. Very comfortable seats and great entertainment. Loved the 5 restrooms downstairs! Great design! Very impressed and I don't impress easily."
Cons: "I may have misunderstood but I thought I heard my Galaxy S7 had to be turned off (not able to use in airplane mode). Really just curious why (if I heard correctly)."
Pros: "Boarding was late and disorganized. Would recommend boarding by rows from different areas of the plain. Flight landed on time. Entertainment offered a wide selection"
Cons: "My wife developed a stomach problem from the second meal."
Pros: "Comfortable"
Cons: "Nothing"
Cons: "The check in and boarding process is always slow and cumbersome at Keflavik - it’s unpleasant to have to be bussed to the plane outdoors and then use stairs to get up to the plane."
Pros: "I liked how kind and courteous the flight crew was."
Cons: "The headphone jack for the movie screen was loose and the sound kept going in and out. The kid in front of me wouldn’t sit still and the kid next to me didn’t speak a lick of English so couldn’t understand me when I asked if I could squeeze by him to get to the restroom. Needed more legroom."
Pros: "Crew was great, seats were comfortable, plenty of space"
Pros: "When I booked my Economy Light fare from Denver to Paris, I was expecting a trying experience. But to the contrary, I found the entire trip to Paris and back enjoyable. I found the boarding quick and efficient, plus the flight attendants were genuinely friendly and helpful."
Cons: "Short answer: Nothing. Icelandair is my new favorite low-cost airline for trips to Europe."
Pros: "Crew was very helpful and friendly, and we were greeted with a bottle of water for the flight. Entertainment is nice with free movies, music and Iceland travel video blogs. Water/soda/coffee offered multiple times, and water additional times."
Cons: "Boarding was walk-to-outside-stairs, more an airport versus airline thing, in truth the fresh air was nice, just glad it wasn't pouring rain. Seat comfort was barely okay, the 757 seats were basically in contact with my knees, tough for such a long flight. Their 767's are much better. Didn't like paying 60 GBP (pounds, about $75) for 3 sandwich lunches with 3 alcoholic drinks, IcelandAir could do better."
Pros: "plane was comfortable, smooth flight"
Cons: "could use more up to date movie selection, crew did NOT smile, food was at an extra cost"
Pros: "I like that there’s a direct flight from Reykjavík to Denver!"
Cons: "Delayed flights, unorganized boarding, sitting on the tarmac for an hour, no complimentary inflight meal for an international flight. Crew wasn’t particularly welcoming."
Pros: "Slightly more leg space than other airlines"
Cons: "My spouse got bumped from an aisle to a middle seat with cold nonchalance. No excuses, no compromises, just plain rudeness from the boarding crew member in Reykjavik. Seems like choosing seats early does not get you said seats with Icelandair. Given the fact that the boarding process was an absolute mess I found it difficult to remain patient. There was no organized line, and only one available boarding agent. Recipe for disaster if you ask me but hey, what do I know. Several agents were present for decorative purposes (?) and telling people that the line was a mess. It is the airline’s duty to organize the boarding process, not the passengers’. Not being served dinner on a 7h+ flight is unacceptable. Food available for purchase was very disappointing in both quality and service. Blankets were not available on this flight while they were on the outbound flight."
Pros: "Excellent in-flight entertainment."
Cons: "No complimentary meal for transatlantic flight."
Pros: "It seems as if the airport is about 25% of the size it should be. One stands in line a lot both in the airport and on the shuttle which takes you from the terminal building to your remotely-parked aircraft: Too many planes and not enough gates. The small airport itself is nice but clearly the growth in tourism in Iceland is staggering."
Cons: "Our Boeing 757-200 was typical -- nothing special -- with the usual cramped seats. The USB ports on the seat backs do not provide power -- only receiving a video signal so you can stream videos from your personal device to the TV screen, I guess -- so you cannot charge your phone or tablet in flight."
Pros: "Movies, price"
Cons: "Not getting food!"
Pros: "The staff was very nice"
Cons: "We were delayed almost 45 mins sitting on the plane without being told why to finally learn we were waiting for a different late plane"
Cons: "Too hot on plane the whole 7.5 he flight"
Pros: "Good"
Cons: "My flight was delayed an hour and a half with no explanation so I almost missed my connecting flight even after sprinting through the airport. I called for a reason why it was so delayed and the customer service rep had a poor attitude and offered little help."
Cons: "My cat was forgotten in Iceland."
Pros: "Size of the Reykjavik airport."
Cons: "Not enough space for legs in the economy class. The chair back support was not working correctly ( couldn't be blocked in the reclined position). Very uncomfortable chairs overall. No food included in the price of a ticket for such long flight? Poorly organized and managed departure process. The passenger next to me was sick looking. He was coughing loudly and frequently all the time during that flight. For more then 7h of the flight no flight attendant demonstrated ANY interest or offered any help. Furthermore when his female companion (wife?) asked just for cup of water so he could get his meds at the beginning of the flight they were told to wait for the regular service to start (what took app 30min). So overall my impression of the Icelandair service is no more then just O'k."
Pros: "Their prices are good see my comments above."
Cons: "Same as above and also the boarding was chaotic with no lines and we had to wait in a freezing bus for a long time before it left. There was a jetway in Denver."
Cons: "Need more food choices that would be good to have as a meal instead of just snacks"
Pros: "We normally really like flying Icelandair and enjoy the ability to have a stopover in Iceland. The crew is always very nice and this flight was no exception."
Cons: "The plane, or at least our section of it, was very warm. We were near the doors between Business Class and Economy, so we were expecting it to be even a little cold, but it was so warm that I was in a tank top the entire flight. The boarding process in Reykjavik was very odd, even for them. There was just a door in the wall under our gate # and without warning it was opened and everyone just got up and went through it. There was no announcement. Apparently the checkin desk was upstairs. We then waited 20 minutes in line, before they finally started boarding us int he order we were queued - again, no announcement."
Pros: "The ride was comfortable and easy!"
Pros: "There was more leg room that we thought there would be; we were left alone to sleep by the attendants. The pilots let us know important information."
Cons: "We were 3 hours late to Denver after leaving Iceland late. This was partially due to weather. The only upsetting thing was the $31 "dinner" available in the airport consisting of a frozen individual pizza, sandwich and 2 waters! We felt like we were being gouged for the airlines issues. The entertainment system on this flight from Iceland to Denver was a bit old and of all four flights, the system was difficult to access."
Pros: "Smooth flight, good attendants, all luggage showed up promptly. Icelandic seating had more leg room than United's 757 planes."
Cons: "Boarding que in Iceland was a free for all, not much structure."
Pros: "Legroom and my bags made it"
Cons: "The boarding makes no sense. If you let people board from 2 ends of your plane, you should at least tell rows 1-20 to go to that door and 21- 35 go to the other. Since that's not done, mayhem ensues. The whole no free food thing is ridiculous but I will either fly a different airline (Lufthansa) or bring my own food. Also the entertainment is what you see on TV in the USA, there are no new movies AND the content is the same east and West bound."
Pros: "Comfortable seats, inflight entertainment, blanket, water, pillow. Food was good (but a bit overpriced)"
Pros: "Good leg room and paid food was good, 1/2 empty flight"
Pros: "Crew was very professional and responsive to a difficult weather situation at the airport in Reykjavik."
Cons: "Admittedly this is something of an airport issue more than an airline issue, however considering Icelandair is one of the few airlines servicing the airport in Reykjavik there has to be some level of coordination going on between the two entities. Regardless, 5 different US-bound flights were all scheduled to leave within 15 minutes of each other in the same small corner of the Reykjavik airport, so when delays started coming in due to weather that area became an extremely congested mess. Perhaps its a cultural norm in Iceland to just remain silent in times of mini-crisis, but the desk attendants made no effort to communicate what was going on to the hundreds of people crammed in atop one another in the waiting area. This led to a lot of frustration from the waiting travelers. Both of these problems could have been prevented by better planning (not scheduling all outbound flights happening in a quarter hour's time into the same small corner of the airport) and better communication from the airline staff, the lack of which really aggravated a difficult situation for the people there. Once on the flight, though, everything went very smoothly, and the flight crew was quite apologetic and professional."
Pros: "The crew were very good and I liked the tools on the back of the seat in front of me."
Cons: "Flight was delayed and we did not really get any info."
Pros: "airline is good overall"
Cons: "Seating is not roomy enough for long flights"
Pros: "On time service. Video selections. On-board wi-fi."
Cons: "1. Same comments regarding cramped seating as above. 2. Boarding in Reykjavik was a total fiasco. Management should visit a European or US airport to see how to load a plane in an organized fashion, as opposed to the free-for-all used in Reykjavik now. 3. Food selection for an over water flight of 7 hours was abominable! And passengers are asked to pay for it too...unheard of for trans-ocean flights."
Pros: "The in flight entertainment"
Cons: "The crew were rude and unwelcoming. Having to actually PURCHASE food and drinks on an international, transatlantic flight is ludicrous. Having made the trip from the USA to Europe many, many times, this was a shock and something that i didn't prepare for. The cabin crew were extremely rude and uncaring. Being offered a drink of water once in 7.5 hours is ridiculous and frankly dangerous for some. This was not a cheap flight, so for such poor service, I think things need to change. A smile from a crew member may not go a miss either. Thanks Icelandair, but i shall not be choosing you for my travel needs in the future, and neither will my friends and colleagues."
Pros: "N/A"
Cons: "When we arrived at Keflavik airport the terminal was immensely crowded with several flights due to leave the US at once. It was overcrowded to the point of being uncomfortable and there was a 30min+ wait to buy food from the only shop. As a result we did not have time to grab a bite to eat between flights. My partner was subjected to additional TSA checks which I am aware is a random check and a nescessity but due to the amount of flights departing for the US this took an extra hour, and delayed our flight. I'm thankful that Iceland Air didn't leave without us but it was an immensely stressful experience that I don't wish to go through again."
Pros: "Nothing to like except that we finally got here."
Cons: "Late departure. Not enough fuel in plane so had to refuel in Minneapolis. Even with headwinds, there should have been enough fuel put into the plane to complete the trip. They stopped in at an airport that was experiencing thunderstorms, and while we were refueling, our plan was struck by lightening and then had to to be examined for damage before continuing on. We were on the ground, in the plane, for a total of 4 hours, waiting. Finally were advised that the crew had "timed out" and could not fly any more that day, so we spent the night and all the next day sleeping on the floor in the airport. Icelandair was not at all prepared for such a situation. Situation was somewhat chaotic with incomplete and inaccurate information given to passengers. Very poor communication on the part of Icelandair, or whoever they contract this function to. We expected to be able to leave the airport the next morning, but were told that the flight would not leave until 5 p.m. Then they changed the time to 8:20 p.m. but didn't announce that. Then that flight delayed until 9:00 p.m. We finally got off the ground a little after 10:00 p.m. On top of all this, many passengers' entertainment systems did not work, and this made for a very long and frustrating flight. Not good, Icelandair."
Cons: "Our plane was diverted to refuel - after an hour and a half of increasingly cryptic and contradictory communications while sitting on the ground, we were removed from the plane and given cots to sleep on the airport floor. No staff present to provide information, no communication by email, noone available by phone, no updates on the website, vague rumors from another airline's staff of a "possible flight" the following evening.....no idea how/when we'd get back to Denver. We got a car and started driving...huge vote of no confidence in Iceland Air, its equipment and staff."
Pros: "Crew was pleasant. Leg room was better then on airlines in the U.S., and it was much easier to get out of the seat with the armrest lifting mon the aisle seat."
Cons: "The boarding process was difficult, as four flights to the U.S. were leaving at the same time and it was almost impossible to get to the gate because of the thick wall of people and no aisles. We were then put on a bus to the plane, but the bus didn't leave for over 30 minutes, well after the takeoff time, and no explanation was given. The temperature on the plane was extremely uncomfortable. Most of the time, it was very hot, and I am accustomed to flights being on the cool side and requesting a blanket. But someone must have been adjusting the temperature, because it would get cold for a short period of time, and then very hot again. It was difficult to sleep because of the temperature. It would have been nice to have some small snacks like pretzels offered with the drinks, and a larger selection of food available."
Cons: "No outlets a big converter box under the seat so I had no footspace."
Cons: "I again did not get 2 seats together on this flight even though I booked 8 months in advance. Flight was severely delayed due to mechanical problems with the first plane. A 757 is not comfortable for a 7+ hour flight if you are over 6 ft tall."
Cons: "Again, at the gate, there were only about 22 seats in the waiting area for multiple flights. It was a mess of people sitting on the floor and standing around. The flight was not called--the board just said "go to gate". How would one know that that meant to board the plane, unless you saw people boarding? I think that the sign should have said "now boarding". Before we arrived in Denver, the crew passed out US Customs forms. I told the flight attendant that Denver has electronic Customs and we didn't need forms. She said that we did. Guess what Icelandair, Denver DOES have electronic customs and that form was a waste of time and paper, since I didn't need to use it at all. Wouldn't you think that an airline that flies into Denver everyday would know that? Other airlines do. They need to get their act together and I don't plan on flying with them again."
Pros: "They upgraded my to economy comfort, which made all of the difference for an 8 hour transatlantic flight."
Cons: "Flight was delayed leaving Reykjavik. I watched our baggage be removed from the plane and head to the opposite side of the airport. It was over 30 minutes later that they announced that there was a mechanical issue with our plane and we had to switch planes. The passengers deplaned, boarded buses and were transported to the new plane. We finally took off over 2 hours late. The other major issue we had is that we were located near the back of the plane and the smell of urine and toilet chemicals was overwhelming. Every time the restroom was used, the stench permeated the back of the plane."
Cons: "Boarding Process was slow. Waiting in the bus was uncomfortable and hot."
Pros: "The aircraft, especially the restrooms, was very clean. The crew worked very hard to ensure our comfort. The seats were as comfortable as they ever get on a 757. R routing slips through the gift shop between arrival and departure is a good idea . Even those with a short connection get a chance to buy a puffin."
Cons: "The terminal at keflavik is under construction this makes arrivals and departures extremely chaotic both on the ramp and in the terminal. The arrangement of gates is so chaotic that it is often very difficult to get to your gate because of large number of passengers waiting in line at their gate."
Pros: "WiFi for purchase!"
Pros: "Crew was great. Quiet for sleepers, attentive to those in need. Smooth skies, easy fun flight!"
Cons: "See above. On the flight from Denver to Amsterdam (you didn't ask about this, but I'll comment anyway), we had business class seats. They were really little more than large regular seats with legroom. We did get food on the flights, unlike the economy class. I have a major gripe about Icelander not telling you how their definitions of seating class differs from the rest of the Western airline industry. Quite deceptive."
Pros: "The previous Icelandair flight from Paris to Reykiavik was late and arrived over an hour after the scheduled departure time for the Reykiavik to Denver segment. We were assured that the flight would wait for the late arrivals, and it did. We were, of course, greatly relieved. I can't help wondering, however, How could a scheduled flight be held up for this long and how would the passengers already on the plane feel."
Cons: "Only drinks like water, tea, coffee and juices are served free on Icelandair flights. There is a menu for sandwiches and snacks. But the selection is rather anemic for a 7 hour long flight."
Pros: "Crew was very nice. Loved being able to look out the window to see all the beautiful terrain."
Cons: "Not having a hot meal on the plane. Since I didn't have time between connecting flights to get something to eat or use the toilet, that would have been nice."
Pros: "Smooth flight even when descending into Denver with stormy skies."
Cons: "Biggest complaint is that a foot got broken off my largest suitcase somewhere between London and Denver. Not possible of course to tell when that happened, but it makes the suitcase pretty unusable now. A plastic connector for a strap on another suitcase got broken on my outbound journey too. Luggage handlers must be unnecessarily rough with the luggage to make that happen. Not sure I'll fly Icelandair again because of that. I was not able to get the "my journey" screen to work on the screen, but otherwise the video and sound qualities were good and controls worked well. After landing, something made a terrible squeal while taxiing to the airport (landing gear?). If my car sounded like that, I'd surely take it in and get it fixed!"
Pros: "Nothing. I was offloaded minutes before boarding by BA without any explanations. The staff was not helpful in any way. BA is suggesting either non recept of payment or credit card fraud. Both reasons are totally bogus."
Cons: "Proper communication by both BA and local handlers at the airport in Iceland."
Cons: "My flight was serviced by British Airways. The temperature in the cabinet was very warm and there were no fan controls. The seats are very narrow. Miserable 9hr flight from London to Denver"
Pros: "Flight crew was amazing. Food was good and there was plenty to make the time go by faster."
Pros: "On time arrival"
Cons: "In general I like the flight stability of 747s. However the seats were very cramped for such a long flight, and unlike more modern aircraft, the seats lean way back pinching the person behind. Entertainment system is rudimentary at best, with few choices and a minuscule screen (but I shouldn't complain, at least there was something to watch). Also, at Heathrow airport (nobody's favorite airport) we had to board buses to get to the airport and walk up stairs. Inefficient, and difficult for older passengers such as myself."
Pros: "The Food, the Drinks,the Comfort and most of all the Friendly Crew. It was a wonderful flight and that should be considered as a complement coming from an Irishman. Many Thanks. Patrick"
Cons: "There was nothing that I did not like about this flight."
Pros: "Crew was pleasant and food service was good"
Cons: "Not a very big or good quality selection of movies and viewing screens were hard to see"
Pros: "Fantastic crew and food reasonable for plane food. Air blowers didn't work. But all in all I had a comfortable flight. Don't like layout of Heathrow - everyone super nice but bus rides between terminals cost me 30-40 minutes having to go through security again. I understand the need but would be nice if flights came and left from same terminals where possible."
Cons: "The entertainment screen stopped working mid way through the 9+ hour flight. Plane was older. The head rests were weird - they weren't flexible so hard to hold in place."
Pros: "I liked that the seats were very comfortable and had enough space."
Cons: "I didn’t like that I had to go through security twice once upon arrival and once in London. i also wish I would have booked a different airline so I could have had a direct flight. That wasn’t a problem with this airline though, just my negligence with research."
Pros: "Things went as planned in the beginning. The young lady who checked me in at the BA counter was very friendly and helpful. The preboarding and boarding went very smoothly as well."
Cons: "The plane boarded as usual then things went wrong. There was apparently something that went wrong with furl getting into a separate storage tank (that's scary in itself...how does that happen?) and they announced that they couldn't get the fuel tank to fill completely and the mechanics needed to get a "special tool" to complete the process. Then they needed some "tool" to drain the fuel from the mysterious storage tank. That was done and they announced that they had decided that they had plenty of fuel to make it to Denver. An hour and a half later of sitting in a sweltering hot cabin the y announced that the mechanical issues were taken care of BUT we'd have to wait another 20 minutes to take off because of the traffic waiting to leave Heathrow."
Pros: "We enjoyed the entertainment, the food, (dinner, snacks, ice cream, juice and wine) the service and the crew. After our flight from Madrid to London we were expecting the worse as that flight was dismal. We were pleasantly surprised that this flight was on a clean plane with great amenities."
Cons: "Boarding was a bit sloppy and of course traveling to the US adds an extra layer of crazy to everything with their added security."
Pros: "Direct flight London to Denver. Check in and boarding very easy, friendly and efficient."
Cons: "Seats very close together, entertainment poor (and not working for first hour of flight)"
Pros: "The crew was incredibly kind and helpful, the food was excellent and we even got ice cream!!!!!"
Pros: "Great dinner. Friendly service."
Cons: "Small video monitors with poor picture quality and sound was also difficult to hear. No power jacks. Oh, and 2 hours sitting on the tarmac because of a “bag discrepancy.” If the bags can’t get along, who really cares!"
Pros: "747s are good stable planes in flight"
Cons: "The greatest problem was dealing with the usual chaos and discomfort of traveling through Heathrow airport. Primitive and time-consuming transportation system between terminals- Had to ride overcrowded buses packed with so many people that your body was pressed against your neighbor. Inadequate number of restrooms and poor signage to find them. Bad selection of restaurants. Then at the terminal, boarding time listed as 10:40, but they did not even announce the boarding gate until 10:40. Then a 10 minute ride on another overcrowded bus to the plane which you had to board by a staircase (and a staircase to the door on a 747 is no small thing!) Although flight was smooth in the air, the pilot landed so "hard" I thought the landing gear must have been damaged!"
Pros: "It got me where I needed to be with a reasonable seat. I got a arrival card from the flight attendants."
Cons: "The boarding process was not very clear because we were away for the first announcement and then no more details were provided that we heard, so we just got in line. It seemed like nothing was free on board, including water but I could be wrong. If there was free stuff, it was not clear, which is annoying. They gave me an arrival card, but no pen or pencil or anything to write with."
Cons: "The plane was actually about to fly off when it suddenly skidded to a stop. We weren't informed about the reason, but all of a sudden, the plane couldn't take off for over two hours. My family and I ended up missing our connecting flight home. BA tried compensating with food vouchers and rebooking us onto another flight, but our family got split up in the process and we were all assigned to different middle seats."
Pros: "Nice crew"
Pros: "NA"
Cons: "The transfer from T5 to T3 was chaotic. Queues to join queues to get the transfer bus. People were getting caught on a moving escalator because the crowd in front had nowhere they could go to make room. Extremely dangerous! It took longer to get from T5 to T3 than it did to get from Dublin to London. Boarding in T3 for the flight to Denver was almost as bad. Bodies everywhere, no organisation and no help. Then the aircraft itself was so old with uncomfortable seats and an almost unwatchable screen. I will never transit through LHR again."
Pros: "Crew were fine, food okay, found a decent movie. All things considered it was all right."
Cons: "Boarding. Second time in a row flying out of Heathrow that I've had to queue up for a bus ride to get to the plane."
Cons: "terrible seats. unable to recline my seat. horrible experience for 8 hours..."
Pros: "Everything"
Cons: "2 drunk guys speaking Russian I think totally ruined the flight. They were ridiculously loud, making it impossible to sleep. Drinking multiple wines, they got louder and louder and more animated and sloppy. Really gross and for a 9+ hour flight, not enjoyable. Eventually, a flight attendant gently told them no more to drink and was very good. But it was too late. I have flown a ton and have never heard passengers this loud, in a foreign language. In addition, one of them was quite large with a bald head, thus intimidating. We had a very long day and just wanted to rest and that was not at al possible."
Pros: "Because we missed our connecting, British Airways did provide us with food and hotel."
Cons: "We missed our connecting flight because somebody checked in and checked bag for our incoming flight, but did not get on the plane. It delayed us an hour. The problem was when we got to Heathrow 45 minutes before flight left, but they had already bumped us from the flight. We could’ve easily made the flight, but they blamed it on the computers, and we had to get on a flight the next day. I think we need to quit relying so much on computers, and use our actual brains!"
Cons: "transfer from terminal 5 to terminal 3 - process was unclear"
Pros: "Flight attendants were to top in the industry. Caring and caring. They are the face of your airline. Give them the right tools, they function well. I could not have been treated better as a Frequent traveler."
Cons: "Reservation process online does not show you that you are buying a bullshit Business Class seat. You pay a premium for Business class and granted, the meal was great, something the Coach class did not get BUT they should tell you when booking that that you are sitting in coach with a table blocking the middle seat, not truly a Business class seat. Dumb down your operations but don't insult your customers. Tell them what they are getting when booking a bus type business class seat. Worst business practice ever, driven by European style of travel BUT call it premium economy, not BUSINESS."
Pros: "Competent crew. Arrived early."
Cons: "The plane was so old it had signs that read, no smoking in the lavatories. The entertainment screen was small and slow to respond. Should be in a museum."
Pros: "Checking documents on entering gate area rather than at boarding time, made for more efficient boarding"
Cons: "Delay in baggage reclaim due blockage in system"
Pros: "Flt attendants. Esp the english guy."
Cons: "Once again just some measly pretzels."
Pros: "Safe on almost on time trip"
Cons: "Checking in at Reykjavic was slow and crowded"
Pros: "Nothing"
Cons: "Nothing was impressive at all"
Pros: "The crew was very friendly and accommodating. Service was wonderful and the food was good."
Cons: "Boarding was very disorganized with only signs showing for priority boarding. In flight entertainment did not work for first half of flight. Once it began to work a little, there was no notification on how to use it since it was still not working properly."
Pros: "We did enjoy the movies and the crew was very friendly and helpful."
Pros: "British Airways code share is always nice"
Cons: "Older 747 not quite as nice as the Dreamliner but it made it!"
Cons: "Nor too many good movies to choose from. I get it , row number 47, don't expect any 1st class comfort, but still, i was glad to land in Denver. Started to run out of sitting positions that didn't hurt."
Cons: "Flying is uncomfortable and painful. The seats are thin with little padding. I kept getting poked and prodded by the person in the seat behind me, and it wasn't even a little kid kicking the seat. I have a problem with my foot, and there is piece of hard plastic or something that runs the length of the plane, under the aisle seat. I had to make sure my foot didn't rest on time because it was painful to my foot."
Pros: "Fight was on time. BA Crew always do a nice job."
Cons: "The entertainment on the flight didn't work. It is not easy to have two small kids on a 9 hour flight when the entertainment system isn't working properly. We did bring our own items to entertain our kids but with the limitations on what you can carry on we were banking on them being able to use the in flight system."
Pros: "Everything was first-rate"
Cons: "The inflight movie service is, in our opinion, worthless because of the noise. If you had closed captions available that would work."
Pros: "Friendly staff and decent food, loved the entertainment and maps screen."
Cons: "We paid for upgraded seats but ended up at the rear of the plane? Very disappointing, I have a refund request in the works."
Pros: "I'd like to mention Ramon, a crew member on the flight, who was extremely helpful and kind. Also, the food was quite good."
Pros: "The first class steward who helped us when he didn't need too. The free films."
Cons: "I flew British Air in the past and had excellent service. I actually would have paid a bit more to choose them as an airline. No longer! Horrible service. Our stewardess was rude and unhelpful. Best example, when my husband turned in the remains of his last meal, something had leaked over his tray table. She didn't bother to help. He luckily had some extra napkins. She watched him clean it up and then left without taking the soiled napkins. Thanks. The meal quality was poor on the international flight. American handled the start of our vacation. Such a superior international flight quality compare to British Air."
Pros: "Nothing"
Cons: "They wouldn't book is into our flight from a different terminal causing is to miss the flighr"
Pros: "Service, comfort"
Cons: "They lost my bag due to flying a 3rd party "Vueling" and did not add my FF# and would not do it at the airport so now I have to sort through online pages and phone queues to do something that definitely should have been feasible and included at airport (I added it on my outbound flight but because of this 3rd party being the originating operator of my return flight it was not included on my return)."
Pros: "upgrade"
Pros: "The staff was friendly. The food was great. There was plenty of entertainment to choose from."
Cons: "N/A"
Pros: "The BA flight attendants still know the meaning of great service."
Pros: "LOVED the folks on this airline. So nice and accommodating."
Pros: "Crew were attentive and competent."
Cons: "The food was just not very good which is a bummer since it was a long flight."
Pros: "Fantastic chicken curry! Best airline food EVER! Nice stewardesses too....."
Cons: "I suppose I expected a slightly bigger toilet on a 747, but no biggie."
Pros: "Great flight. Good to have beverages served frequently. Crew efficient and very pleasant. Comfortable and safe flight."
Cons: "Could not hear boarding announcements---no microphone, so just guessed where to be."
Pros: "We were not looking forward to the near 9 hour flight, but BA made it a very comfortable & enjoyable experience. Drinks & snacks were offered frequently. Individual monitors for movies, music etc. made the flight a great experience. Fantastic crew! BA airport staff helped locate our lost baggage and followed through quickly with returning it to us. We can't wait to fly with British Airways again!"

The plane was SO hot and we waiting 30 min for one passenger to get on. Sweating. Then the plane never cooled off because it got SO hot waiting.

Pros: "Everything basically"
Cons: "Nothing"
Pros: "Crew was great."
Cons: "turbulence"
Pros: "1st class flight attendant sat through the entire flight (except for offering drinks and food early in flight). There were passengers NOT wearing masks through the flight but she wouldn't know that since she never left her seat"
Cons: "just about everyting"
Cons: "IFE was not streaming movies, WiFi on but not loading"
Cons: "Spacing people out until this covid is over"
Cons: "There are too many announcements on the screen before you can start watching entertainment. It takes about 15 minutes."
Cons: "Not a thing. Good airline, all the way around"
Cons: "Short flight, would have appreciated if when asking for pretzels the flaggt attendant didn't hand me the spare bag of his pockets."
Pros: "Really enjoy flying first class."
Cons: "Excellent"
Pros: "Everything was great"
Cons: "Nothing"
Pros: "Appreciated the pilot keeping us informed re: turbulence and avoiding it"
Pros: "Crew was tight, friendly, flight comfortable & painless."
Cons: "Only pretzels, came eat refined flour, nuts or something else would be great."
Cons: "There was literally no entertainment for over three hour flight and our flight was delayed an hour while we were on the plane."
Pros: "On time flight. We were even a little early."
Cons: "Those seats are just crammed in there aren’t they?"
Pros: "The notifications regarding my connection and baggage claim."
Cons: "Nothing."
Cons: "American Airlies no longer partners with T-Mobile for free WiFi. :-("
Pros: "Overhead bins were newly done with plenty of space since carryon can be placed vertical on side. Decide holder built into the seat was very nice."
Pros: "Nice staff"
Pros: "Jesus, the flight was phenomenal! He lightened up the atmosphere with his wit and grace."
Pros: "Love FLIGHT WITH AMERICAN AIRLINES."
Cons: "The sound on the entertainment system in my seat didn't work well. Also, the flight was really late getting in to Denver."
Pros: "Fine for a domestic flight. Normally, American Airlines offer a small snack to go with the drinks. But on this particular flight, they went the United way and offered nothing but drinks. Crew was pleasant enough during the flight, although they didn't greet half of the passengers entering or exiting the plane."
Cons: "Flight was a little late taking off and therefore getting to Denver. But there was no announcement about it. There was one announcement from the captain, but it was so soft that I couldn't hear anything. Upon landing and arriving at the gate, we stood there for a while with no lights on and seatbelt sign on, but no explanation of what was going on. There was no welcome to Denver message either. Maybe their announcement system was down."
Cons: "Flight departure was delayed for 30 mins by a flight attendant not showing up on time."
Pros: "Seats were too tight and too close together."
Pros: "Nothing in particular"
Cons: "Outlet did not work"
Cons: "Flight crew was late and didn’t try and make things move faster to make up time. Kept saying they wanted to go Puerto Rico and that’s where they should have been going."
Cons: "Flight was delayed by 90 minutes because the incflight mint flight was late"
Cons: "the drink service came through pretty late in the flight. i asked for hot tea. a few minutes later i was provided with extremely hot tea. about 10 minutes later it was a temperature i could tolerate drinking. about 1/3 through the drink i was required to throw away my drink because we were preparing for landing. i understand that, fine. bad timing. it’s just a drink. what was unsatisfactory is that the attendant rudely commented “you have to give us your drink. it’s not that long of a flight.” the comment made me feel like i had done something wrong even though i had just been drinking my tea as soon as it was at a drinkable temperature. i was not impressed with the attendant. also, there weren’t any biscotti cookies."
Cons: "Food"
Cons: "The gates closed early and I missed this flight! Horrible service, never flying American again."
Pros: "The first leg had awesome pasta.Then, on the 2nd leg, Philly to Denver, they had a "pay for meal" option for turkey with Chutney sandwich - again, delicious. I should add that the service was very good as well."
Pros: "The onboard entertainment selection was excellent; great movie selection, wifi connection, and flight details. A winner! So much so that I chose to binge watch movies and not sleep!!"
Cons: "No tvs!!"
Cons: "Long delay"
Cons: "Missed that flight because my finair was delayed at Helsinki"
Pros: "Crew"
Cons: "Small plane"
Cons: "Watched a very weird interaction between Muslim (with a hajib) women with a kiddo and desk crew. She wanted to sit next to her child on the flight and needed to switch seats to be able to. Woman was very gracious and understanding that she was asking for an accommodation. Ends up her flight to Philly had been moved to a different gate after they had found a volunteer to switch seats. Volunteer was totally unfazed but Desk crew made it seem as tho the Muslim mom was at fault for the time and trouble they had had to go through to accommodate her. She apologized profusely and was very appreciative for the trouble evernote had gone to for her. . As she walked away the crew looked at each other and shook their heads. Pretty crummy way to treat customers!"
Pros: "Missed the flight. Money was not refunded."
Cons: "Nothing"
Cons: "I can't rate it because they canceled my entire itinerary without so much as an email. I did not take my flight to Wilmington via my original flight. I had to book another flight because the change fees were too expensive. I did not know that my return flight to Denver had been canceled until I was checking in a few hours before my flight. I was told my ticket had no value. Awesome! It really stings that I then had to book a new return flight, and because I am a teacher who makes about $23,000 a year, I had to book the cheapest flight, which was with American. I do not plan on giving them any of my hard-earned money in the future if I can help it."
Pros: "The crew were as nice and accommodating as they could be considering the situation."
Cons: "Three planes with "maintenance" issues and not able to fly? Including flights that weren't ours. Boarding, re-boarding, leaving four hours late and waiting an hour for bags in Denver."
Cons: "The flight was 3 hrs late, of which 1.5 before boarding, and almost 1.5 stuck in the plane."
Pros: "I fly this route with American pretty often. The cabin crew was good. Everything else seemed sub par."
Cons: "Our take off was delayed, officially due to fueling the plane, but if the plane wasn't fueled ahead of time, someone failed to do their job properly. Also, while I'm starting to think that A320s just suck mechanically for landing (they always seem to land harder than a 737), this one seemed a little extra rough."
Pros: "We were able to get to Denver"
Cons: "Jammed in like sardines, rude flight staff, extremely hot aircraft for November"
Pros: "Crew"
Cons: "Had to board three times, two different planes. I understand mechanical problems, but 3 hours later, and on another plane, the captain starts making stuff up, saying that the only reason we hadn't moved in the last hour was because people were using the bathroom, then something about having to deplane because the plane couldn't back up with us on it because of some sensor? And then, surprise ! All of the sudden they noticed there was an issue with his and some of the crews' hours and we had to wait till they could locate more crew. But they gave us each a 1/3 glass of water and later a $12 food voucher which didn't even cover a meal and beverage. Whoop-de-do. 7 hours later we finally boarded for the third and last time. The crew on the other hand stayed professional and friendly."
Cons: "When your on your honeymoon it sure would be nice to have a seat next to my husband like we requested."
Pros: "The plane was new on the interior and comfortable."
Pros: "They showed American ninja warrior."
Cons: "Everything. The flight was delayed greatly even though the plane got to Chicago only slightly late. Then they make us board and just sit in the plane for an hour. Then finally we start moving, the plane is uncomfortably hot even with the air blowing on me, the flight attendants look like they hate their life, it was honestly horrible and I will never fly with American Airlines EVER again."
Cons: "The service was terrible, 4 hour traveling and not food."
