It would have been much better if the plane actually departed. The flight was canceled, so it took me about 36 extra hours to get home

Left our luggage in Frankfurt on purpose. Did not send email as they claimed. Misleading notice of free luggage checkin.

Super comfortable. Slept the whole way.

So many minor delays, very little communication, and what there was, we couldn't even hear in the first place.

No delays Better food Nicer staff

Check in and security in Faro was a breeze!

Ridiculous unnecessary "extra security" checks at the gate before boarding. With mostly everyone vaccinated and everyone tested, requirement to keep the face covering on between taking the bites seemed a little excessive. Seat assignment - flying with my daughter were assigned seats at opposite sides of the plane, when asked for change was told that there were no 2 seats available together which proved to be not true when after boarding was complete.

Pros: "I had a connection flight which would not be for another 11 hours so I left the airport to get some sleep coming back the same carry-on I have with me now cannot come with me they want me to pay 40euro. In the meantime the flight is 40% empty and plenty of over head and yes is the same size of plane I came in the first place. However the agent was nice after I explain my situation she not charges me."
Cons: "Same airline coming from one place have different methods it’s a bit confusing."
Pros: "Fantastic crew!"
Cons: "Both outbound and inbound flights had defective/nonfunctional entertainment screens at our seats."
Pros: "Crew excellent...seats small and not too comfortable for business class."
Cons: "Due to a delayed flight the night before, we were rescheduled and consequently missed another flight. Nothing was done about this since it was a separate trip. We had to pay another $1300 for new airline tickets to get back to the US."
Pros: "Seat was OK"
Cons: "Good"
Pros: "The crew was helpful and nice."
Cons: "Nothing really."
Pros: "Crew was nice. I will go again with Lufthansa."
Pros: "Airbus A380 -- the most comfortable and quiet passenger plane that I have ever flown in Very friendly service, who even remembered my name!"
Cons: "Horrible flight"
Pros: "Excellent service, food and entertainment"
Pros: "Boarding was efficient. Crew was very professional and nice."
Cons: "Arguably the worst food I have ever experienced in Business Class. Entertainment was average. Seats not all that comfortable for sleeping on a 12 hour flight. Also, it was hard to hear the announcements over the PA system."
Pros: "Did not make this flight due to lines at Frankfurt security. Customer service has been awful, had to wait two hours to speak to anyone and ended up purchasing another flight because they sold out of all decent connections."
Cons: "This has been the worst customer service experience of my life. Never flying Lufthansa again."

Pros: "Very comfortable journey, was a pleasure to travel."

Cons: "The crew change the seat with a new boarding pass without my permission . They are not professional at all"
Pros: "Reliability, usual Lufthansa service"
Cons: "Delay due to technical problem with the aircraft, however better that than any consequences of that. Food is rudimentary, and there is no vegetarian version of the sandwich any more."
Pros: "Arrived with enough time for me to connect to my international flight."
Cons: "Boarding had no clear order. Had an international connecting flight and by the time I needed to board, there was no room in the overhead and I had to check my luggage. The airline should provide a vegan snack option for customers."
Pros: "Best short/medium-haul economy breakfast I've had in a while. Flight was empty, so there was space to stretch out. Watch out for the seat maps – they seem to reconfigure the J/Y balance on this flight frequently, so your seat assignment may change. Such a lovely crew"
Cons: "Moscow passengers were awful as always. Arrival/transit at Frankfurt is a nightmare if you need to be somewhere quick – just walking and riding transit took 30 min. of my two hours."
Pros: "On time and professional boarding. Comfortable flight and friendly flight attendants."
Cons: "Nothing to say."
Cons: "Refusal to board as our flight was a few minutes landing"

Pros: "Quick loading and departure."
Cons: "The gate changing 3 times."
Pros: "The food and service is always good. In flight entertainment and nice planes!"
Cons: "To board- it's just a long queue - any way to shorten line so we don't have to stand for so long?"
Pros: "I like flying with Lufthansa. It is one of the best airlines to fly with but a bit pricey."
Cons: "The food was not good at all. For a flight that cost so much, the food could be better."
Pros: "The in flight crew was great"
Cons: "I arrived a bit late to the airport. 5:15pm for a 6:05p for an international flight. I realize It is very late. I was delayed by donald trump protestors blocking the highway (not your fault). Dulles was a ghost town ( abnormally slow). All I had was carry-on. They said they closed the flight. They quoted me at $1800 for a one way ticket directly from Lufthansa. The original round trip was $900. I declined, sat down for 15 min booked another Lufthansa flight online for $800, checked in and was through security by 5:50. Just in time for my original flights last call. I could have made it easily. Boooo Lufthansa booo."

Cons: "The special meal I got was not the same as I ordered."

Cons: "The flight was delayed from Washington DC and from Frankfurt"
Cons: "Less knee room than usual. Very cramped."

Cons: "Transferring flights it was difficult to make it to our flight on time. More snack options would be nice."

Pros: "Fast trip"
Cons: "No entertainment"
Pros: "I love the Service the attender provided"
Cons: "None"
Cons: "Food options"
Cons: "The check in was very slow - only one Iceland Air representative was at the counter."

Cons: "Seats small. Surprised no meals unless purchased. But didn’t matter too much I ate before the flight left. And it was nice to have something to purchase if needed. It was confusing where I could purchase my baggage ahead of the me while checking in online so I just paid for it once I got to the airport."
Pros: "Nice flight. Empty seat between the two of us! Arrived earlier than expected."
Cons: "Nothing."
Cons: "Baby in front of me and baby next to me took turns screaming during the entire trip."

Pros: "the route and speed of transfer to the next flight"
Cons: "Poor range of foods, limited supply available by the time the crew gets to you. Tea was made in a coffee pot and tastes horrible."
Pros: "Kids get activities and a special meal box. Flight attendants were helpful in making our row restful for my kids to sleep. Nicer flight than I expected."
Cons: "Nothing - would fly again!"
Cons: "Lack of food for a 7hr flight"
Cons: "No dinner meal served and only one beverage service for 7 hour flight. Had to wait a very long time to order a noodle bowl and beer (not complementary), which were mediocre. Iceland air does not recognize global entry, therefore I could not get TSA pre-check or expedited customs."
Cons: "3 hour delay from Denver translated into a 6 hour delay to my final destination. Food on board is expensive, even when other airlines offer food in their ticket prices. Very likely will not fly on Iceland Air again."
Pros: "The crew members were very nice and always friendly."
Cons: "No meals served in flight, entertainment selection was very poor. No communication regarding long delays.."
Pros: "The crew was courteous, and polite. Vwry helpful, and the flight was extremely fun, ibe never seen so much in my life, and being able to follow the flight path was my favorite."
Cons: "Because i didnt have an aisle seat, sometimes they seemed to forget I might habe rubbish, but overall they were always walking by to assist. Still a positive."
Pros: "The flight was quiet and I was able to get sleep on the transatlantic leg. Passport control at KEF was quick and plenty of nice places to wait during my layover which had been extended thanks to anweather delay.frie"
Cons: "Hard to rate food when it's for purchase and I didn't consume any. No drinking fountains at KEF Food for purchase only"
Pros: "Great in-flight music and movies. Top notch. Friendly and quick service too."
Cons: "Airport in Reykjavik was awful. They had 5 or 6 flights leaving at the same time out of the same wing and so there were crowds of people standing around with no direction..."
Pros: "On board entertainment was good (i.e., movies, shows, etc.)"
Cons: "No food was served."
Pros: "Very comfortable seat in row 5"
Cons: "The flight from Denver was delayed an hour. Our connecting flight in Iceland DID NOT WAIT for the seven of us. We were supposed to be in Geneva 3 hrs later but waited in iceland 7 hrs the sent to Frankfort Germany before being flown to Geneva 24 hrs after departing Denver. We had two toddlers with us. There were flights on other airlines available without delay, Icelandair had no compassion."
Cons: "First time I have flown on the international flight and there was no food"
Pros: "The crew is always excellent"
Cons: "That you do not serve food"
Cons: "My wife's bag did not make the plane from KEF to AMS. Still hasn't arrived 30 hours later."
Cons: "Depending on the seat you get (aisle, middle, or window) you either can or cannot fit anything under the seat in front of you. Each seat has different space. What I usually take wouldn't fit anywhere but the window. The middle seat space is USELESS as there is something installed that MAY give you about 6 inches from floor to it. The aisle seat's forward under space is a cube shape, so typical carry-ons won't fit there either. As I slept the whole way to Reykyavik, I don't know much about the service. The under seat space may lead me to not booking Icelandair again."
Pros: "Icelandair is great because your connection waits for you even if your flight is late."
Pros: "Nice warm blankets."
Cons: "45 minutes to change planes and go through customs and use the restrooms is too short."
Pros: "The crew was nice and it was nice that they gave my 8 year old son an activity bag and free meals. The entertainment center was great. The flight was on time and everything seemed to run smoothly."
Cons: "It felt like a domestic flight in that there wasn't a lot of extra space and we had to pay for everything (food, snacks, headphones, wifi) aside from soft drinks."
Pros: "On time"
Cons: "No food or drink amenities"
Cons: "No blankets and the temp in the plane was freezing. Possibly this is only for this specific flight, very little info on delay and almost no info on what was going on."
Pros: "Nice leg room. Nice crew."
Cons: "Seat very uncomfortable; rear end very sore. TV unit kept coming back on after being shut off."
Cons: "Arrived late."
Pros: "Entertainment options, crew was very polite and helpful"
Cons: "Any overnight flight should provide a meal or better meal options to buy"
Cons: "Meals on menu were not available."
Pros: "Pillows and blankets. Lovely crew"
Pros: "I enjoyed everything about my experience with Icelandair. I am going to be flying into London through them for now on and hopefully on an annual basis!"
Pros: "Was offered a seat so we weren't seated 3 across on our side of the aircraft"
Cons: "I preordered a meal that they didn't get from the caterer and none available on board. Waiting area for flight had no seats."
Cons: "The movies were all old, no new variety. They refused to let us take our bag on to the plane even though it fit in their provided sample bin and made us check it at the gate. There was plenty of room on the plane bins and several bigger backpacks than our small duffle bag! This caused us a lot of extra time spent upon arrival waiting for it"
Cons: "you cancelled my flight, no more Iceland air for us, we had to cancel our entire vacation."
Pros: "Nothing"
Cons: "Flight was cancelled & no alternative flight was offered. Had to spend $350 more for a last minute flight & lost a day's vacation"
Cons: "No food served in economy. Bought a tapas box for 11 euro that was not worth even half that."
Pros: "Flight nice, easy, crew good. Good seats. nothing wrong really"
Cons: "I didnt' realize there was no food at all! Oh well, I guess that's how I got such a cheap fare."
Pros: "Service was good, seat was comfortable."
Cons: "Having to buy a meal on a seven-hour flight is surprising to me."
Pros: "I appreciated the fact that we were able to fly out despite there being a major snow storm and closed airport just hours before our takeoff. We also appreciated being able to switch our connection flight fairly easily once we knew we would be delayed. The staff was very kind and since we had a longer layover in Keflavik, we were very grateful for the food vouchers to used in the airport while we waited."
Cons: "The airline wouldn't make a decision about whether or not the plane would be flying out on time or be delayed until about an hour before our original boarding time. Seeing as the airport and only road getting to the airport were closed, it seems like they would have been able to make that decision and alert all passengers much sooner. We kept calling in to check on the flight status and they said we would receive texts and emails with any changes, but I never did."

Crew was great, food quality was poor. I ordered the lasagna and it was not to my liking.

Quick boarding . Clean plane. Arrived ahead of time . Smooth flight

They did great. My flight got cancelled and they hooked me up with an alternative route same day. Thank you for the help.

Flight was delayed one hour due to a mechanical issue.

On both legs of my trip, going out and coming home, the flights were delayed. I had to run through PHX to get from Term A to B because the delay left me with <20 mins to departure. Staying consistent, the departing flight was late and I made the flight. Seems that a schedule is just a suggestion on American

Pros: "Nothing, no food or water, couldn't get on the wifi"
Cons: "Everything"
Pros: "The crew was amazing and we arrived early! It was the perfect flight!"
Cons: "Put departure kept getting delayed"
Pros: "The crew was so friendly and helpful and nice. Love the whole online entertainment thing that AA does now."

Pros: "Crew was very pleasant and quick with service."
Cons: "There was no in-flight entertainment! This is ridiculous for an overnight, international flight."
Pros: "The flight was mainly smooth, it was a bit delayed, but made the time up in the air so we got in on time."
Cons: "I still don't know how to connect to the Wi-Fi on board. It's odd, I'm a web developer and that's my job."
Cons: "the entertainment on the app didn’t work. and there was no seat back tv things. there was a movie playing in the aisle of the airplane. there was no way to charge any devices while our domestic flight had the tvs on the back of the seats and international plugs for every seat"
Pros: "Seats were roomy and comfortable."
Pros: "Great crew"
Cons: "Stop sending rental car emails with cheap prices and then I try to reserve a car and the price is doubled"

Pros: "The flight crew was pleasant!!!"

Cons: "Delayed for an hour due to a log book issue."
Pros: "Good, cheap flight that gets the job done. No issues boarding, seats were fine. Cannot comment on most things as I fell asleep almost immediately."
Cons: "Would've been nice to have had an eye mask / blankets on a red eye flight..."
Pros: "The crew was fantastic and our seats were exit row which was comfortable. We had terrible weather and the pilots crafted an exceptional and safe landing. The flight attendant was hilarious!!"
Cons: "Nothing. It was great"
Pros: "The flight was crowded, but what can you expect? Turbulence prevented beverage service. The flight arrived early but had to wait to land."
Pros: "Convenient flight from DRO to Dallas."
Pros: "Nothing"
Cons: "Our honeymoon started off with American airlines delaying us by 3 hours in Miami causing us to miss our flight to Iceland and now we are stuck in Dallas paying out of pocket for everything because American does not reimburse anything. Just brutal."
Cons: "They changed my flight schedule that made me have to arrange my travel plan"
Cons: "Gluten free meal not provided as requested. Entertainment totally lacking."
Pros: "I planned a very affordable & organized trip, using KAYAK! Very satisfied so far!"
Cons: "The seating on the plane from the US to Heathrow... VERY uncomfortable!! The food was just ok... glad to be fed, though! :)"
Pros: "Very attentative crew"
Cons: "Charging for WiFi"
Pros: "The food and movies"
Cons: "The lack of communication while waiting to board about why plane was delayed even though it was already there. Service was ok, nothing stood out nor was extremely bad."
Cons: "Unable to access the internet. It was American flight, not Alaska flight"
Pros: "On time."
Cons: "Very little entertainment. Would love some Wi-Fi."
Pros: "Entertainment was great"
Cons: "Wish the seats could've been a bit more comfortable"
Pros: "Nothing"
Cons: "The man at the gate was rude and tried to tell me I needed to pay 50$ to bring on my small purse, while his assistant said I could put it in my carry-on. Even more strict that Spieit airlines and higher prices. They didn't even bring around drinks because of "turbulence" unless you were first class. The plane shook slightly more than a smooth flight for only a small fraction of the flight."
Cons: "Suitcase was damaged during AA/BA FLIGHT from LAX TO DUS"
Pros: "Captain kept everyone in the loop about the problems."
Cons: "Flight was late."
Pros: "The entertainment system is awesome made the flight go by so fast seats were comfortable"
Cons: "While using the entertainment system the airplane announcement system was way too loud I believe you are going to have lawsuits eventually for loss of hearing everybody around me was jerking to take the earphones out of their ears because the announcement system was way too loud across the entertainment system"
Pros: "The boarding process was quick and efficient."
Cons: "This plane did not feature TV at your seat. Only the overhead TV"
Pros: "staff fine On time"
Cons: "Review misleading - I didn’t use entertainment and this flight does not have food"
Pros: "Quick short flight efficient, got from A to B for the same comfort for the price I paid so I’m happy"
Pros: "Flight was great. Crew was very attentive and the flight was under booked giving my wife and I an empty middle seat. The entertainment was vast consisting of movies and TV shows to pass the time."
Cons: "n/a"
Pros: "Food was good and service and crew were excellent"
Pros: "I survived the flight."
Cons: "Missed connection Uncomfortable Rollercoaster flight"
Cons: "Poor choice and food"
Pros: "Cabin baggage allowance."
Cons: "No food, only purchasable snacks payable only with a card not cash. That incurs charges for those that are not US card holders! And extortionate prices. Wifi based entertainment so you need your own tablet/phone. Great if the wifi works - it didn't. Neither on the outward or return journeys."
Cons: "Got a notification of a TWO HOUR DELAY departing SFO. Rebooked into Charlotte instead of Dallas to connect to Fort Myers. THAT flight got delayed AFTER the doors were closed by another 45 minutes which caused me to miss my connection to Fort Myers AND have American Airlines leave my bag in Charlotte. I rebooked into West Palm Beach to drive to Fort Myers and my bag stayed in Charlotte even though there was ANOTHER 45 minute delay to change a tire on the plane. If I practiced medicine the way the airline handled customers, I'd kill every third patient!"
Pros: "Nothing good to say at all about American Airlines. #IHATEAMERICANAIRLINES"
Cons: "We boarde on time, however there was no air conditioning or lighting on. After fully boarding we were told the pilots were going to be an hour delayed coming in! Oh yeah, and the fancy new seats don't have power outlets. #IHateAmericanAirlines"
Pros: "The crew did everything they could for the passengers to make them comfortable and informed about the situation but unfortunately it was out of their hands."
Cons: "It may be La Guardia Airport that is the one to blame and not AA, but long story short I was on the airplane on the ground in NY for about 5 hours. We had a domino effect of things happen that caused us to be delayed and then cancelled. First a Gate change to a different terminal after boarding was suppose to begin so we had to take a shuttle over and we're still missing 50 passengers, Engine problem that required maintenance, refuel because we were in the plane on the ground waiting for so long, deplane and replane for 10 mins because of a law, on the runway and back to the gate for all these different occasions. When they finally let us off the plane after all these hours it was because of weather (although the skies were blue and the pilot was confident it wouldn't be an issue) they didn't actually cancel the flight until 5pm, my flight was suppose to take off at 9am. They were also required by law to give us free snacks Bc we hadn't eaten all day or had fresh air--these were all chips and soda...in gluten free so I had to starve. AA customer relations said they couldn't compensate because the issue that was documented in their records for my flight cancellation was because of "weather"... my flight couldn't be rescheduled until the following afternoon, making me have to cancel work 2 days in a row and pay for multiple taxis and and extra night of boarding. I will NEVER fly AA or La Guardia again."
Pros: "One hour delay caused a missing of a connect flight"
Pros: "It was a fairly routine flight. Could use a more substantial snack for a four hour flight."
Cons: "While waiting for our baggage in Phoenix, we noticed a few random bags with tears, rips and clothes hanging out. Then we saw our suitcase. The zipper was torn away from the lining so that it no longer closes all the way. There items hanging out of the gap. What was happening in the basement that caused at least 4 damaged bags?"
Pros: "Nothing. It was fast."
Cons: "VERY small plane."
Pros: "Comfort and quick boarding"
Cons: "Flight attendants were a bit dry and less than over zealous. Connecting gate in Charlotte was really far from where we landed. I had little time to get there."
Pros: "The cordial treatment by the crew members"
Cons: "Not enough air conditioning, it was too warm on both flights. The foid could be better"
