Airline reviews

Pros: "The flight attendants were all helpful and pleasant. The seats were comfortable. We were provided with plenty of liquids."
Cons: "The landing was pretty tough and we took off almost a half hour late."

Pros: "Very friendly gate attendants helped us fix the problem that our frequent flyer number had not been entered on the boarding pass. This may have been because of the booking co., Just Fly."
Cons: "Would have liked more seat options, like when I book on Delta's website. Didn't have enough advance warning."

Pros: "Food and entertainment was good"
Cons: "The bathroom I used was disgusting."

Pros: "Anything from free WiFi, entertainment, leg room, commentary drinks and snacks. Great service!"

Cons: "Bags never arrived at the listed baggage claim. After 45 min, I saw bags on a different claim station and I notified everyone standing around. BUT, I filed a claim with Delta and was immediately given 2500 miles, as guaranteed!"

Pros: "Comfortable seats. Good entertainment"
Cons: "Going to Denver was delayed and now return trip delayed We were give 3 separate reasons. Poor communication. Just telling me a flight will be delayed is not communication. Lack of a free snack was disappointing. May have to rethink flying Delta next time."

Pros: "Great people and crew early arrival nice passengers"

Pros: "Nothing!"
Cons: "Everything"

Pros: "Delta is great"

Cons: "Poor Delta DEN counter agent experience. Name on ticket didnt match Delta profile name nor TSA [rofile name. Delta counter agent would do nothing, except blame TSA. Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."

Cons: "The crew forgot to turn the heater on in -3°F creating a situation where the lavatory water lines froze. This caused a two hour delay which made me miss the second leg. Because I missed the second leg I was put on the very last flight out of ATL and got to spend Xmas eve in the airport."

Pros: "Crew was nice."
Cons: "The Entertainment sucked. Again I was sitting in comfort class which in theory should buy you more comfort and better entertainment. There was a ton of movies from the 90s and the same movie selection from about 6 months ago when I traveled with them. Also, what is going on, with having to use your own cell phone to watch movies on the plane? Whatever happened to the screens in the backseat of the front seat? I ended up with neck pain from trying to watch a movie on my phone. Delta has become very cheap. It is going into some serious decline."

Pros: "Nothing"
Cons: "Let me just say that I’m a loyal Delta costumer until now. The flight attendants (the two women) were an absolute nightmare. They were so rude and condescending. I was carrying with me my service dog and a bag containing an expensive medication (it couldn’t go on the top bin). Despite being in the comfort class and having the seat next to me empty, we were tight for space. The flight attendants were unreasonable and forced me to put my medication on the top bin despite the fact I had told them it was extremely delicate, that it that to go upright, and that I needed to keep it with me. They did not listen and pressured me into giving them the medication. The medication could have easily gotten broken. Thankfully it didn’t but this is no way to treat a human being."

Pros: "Entertainment system is awesome and similar to what I usually see only on international flights."

Pros: "Most comfortable flight I have taken in some time. Spacious seat, power, good entertaiment, attentive flight crew. On time. Not usually a Delta flier, but times and destination made Delta the choice. Turns out a great choice."

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "Nothing"
Cons: "That I couldn't reschedule due to the hurricane. I got stuck in Texas because of the hurricane. They didn't want to reschedule the flight because Denver was not apart of the affected area."

Pros: "Staff was courteous, flight uneventful but that's a good thing!"
Cons: "Long flight, difficult to sit that long (3 hrs plus)"

Pros: "Excellent crew and comfortable flight"

Pros: "Friendly Staff"
Cons: "Check in was very hectic due to limited staff and getting bumped by the red carpet flyers. Boarding is always a little congested due to the lines. Better snacks please!!"

Pros: "It's a nice, comfortable flight with plenty of entertainment options."
Cons: "The coffee on board is lousy, but I'm not sure that is much of a surprise."

Pros: "We purchased economy tickets in Delta. With these tickets you don't know where you are sitting until you get to the airport. Well, we lucked out and got the Plus seats! We got free alcoholic drinks, and big plush seats! We left right on time and got there early! Overall a great experience!"
Cons: "Nothing."

Pros: "Great,I loved it!"

Pros: "Food, crew, boarding"
Cons: "I had a screen in front of me that did not work. It was annoying. Fix it."

Cons: "I fly Delta quite often, and am usually pleased with their service, but the morning of June 23 was terrible. I got to the airport in Denver at 5:30 am for a 7:30 am flight to Atlanta, and the line to check a bag was about 40 people long. I waited 55minutes to check my bag, as they kept moving the ski priority people, and people in danger of missing their flight, to the head of the line. There were obviously not enough Delta workers on staff to process all the flights at that time."

Pros: "The moviea"
Cons: "The time of night"

Pros: "Everything else fine."
Cons: "Made me check my bag - even though ther was plenty of overhead bin space."

Pros: "I didn't like anything because the fly leat 3 hours"

Pros: "First we had a mechanical after boarding. I was rerouted through Atlanta. That flight is now delayed by 2hours. I then had to reroute to West Palm Beach instead of Ft Lauderdale. I will leave 9 hours after my original flight time and arrive 8 hours later. Just ridiculous"
Cons: "See above"

Pros: "The cabin crew serving the main cabin were exceptional. They were efficient, kind and FUN. We were an hour late leaving and 2/3 of the plane was worried about tight connections. They handled it with grace giving each person their departing gate and asking everyone to let a gentleman off with a 10 minute connection. They made the flight memorably enjoyable."
Cons: "Being an hour late isn't ideal and I understand that it wasn't their fault (the plane was late arriving into Denver. Those things happen. They still goto people to Detroit in time to make connections--barely."

Pros: "Smooth ride. Delta got everything right from takeoff to landing."

Pros: "Entertainment options"

Pros: "The flight attendants were so nice and accomadating. Even came by to refill our waters! I've never been on a flight with such friendly flight attendants!"

Pros: "Reassignment was pretty easy."
Cons: "No accommodations were available for overnight stay due to delayed flight."

Pros: "Upgraded to first class"
Cons: "No entertainment system, no power outlet...for first class this is disgraceful"

Pros: "The flight crew was great"

Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."

Cons: "Seats too close - I'm not that tall and my knees were jammed against the seat in front of me."

Pros: "Was able to get on a flight after ours was cancelled. Delta was in scramble mode and their gate staff worked hard ot deal with a frustrated flying populaiton"
Cons: "After paying for first class round trip airfare, we were given seats in coach in the rear of the plane, in spite of empty seats (plenty of them) in first class and economy comfort."

Pros: "Plane was clean and staff were friendly"
Cons: "The snack options were quite average"

Pros: "Flight attendants were lovely"
Cons: "Nothing"

Pros: "The crew was very nice"
Cons: "Most of the food on the menu was not available"

Pros: "Excellent customer service. That doesn't seem to happen too often with airlines. Delta has been outstanding."
Cons: "No complaints."

Pros: "Flight took off on time and arrived about 30 minutes early."

Pros: "on time travel care in treating my visitors from Kenya Africa"

Pros: "The flights back to anchorage were much better than the flights out of anchorage. They were on time and everyone was very helpful."

Pros: "you still get a complimentary snack and drink"

Cons: "I had no room to move and my legs were stuck"

Pros: "Only 15 mins."
Cons: "Seats were tight."

Pros: "aircraft was new, clean, and with many new amenities that are appreciated - device charging, Internet access. The crew was great."
Cons: "The seats are tough after a few hours of siting. Children screamed throughout the flight. To the crews credit, they recognized the issue, and suggested a move to empty seats. However,there was a screaming and coughing child behind these seats also. Perhaps grouping families to a section would help?"

Pros: "The usual efficient, friendly WestJet crew. Nice to fly in one of the new Dreamliner. Super smooth landing."
Cons: "Nothing."

Pros: "Premium seats were more comfortable, crew in our section was great, newer airplane was lovely, food and drink were really good."
Cons: "Can’t think of anything within WestJet’s control that was bad."

Cons: "Minor point. They boarded the plane very early. We got to the gate 1/2 hour before departure, and were almost the last ones to board."

Pros: "Didn't see much of crew. Food was crazy expensive for what it was."
Cons: "Better food for price, or an option to pre-book a proper meal at time of buying ticket. Plane was cold and no blankets."

Pros: "The plane was nice and quiet, and the crew was lovely."
Cons: "It was so cold!!"

Pros: "I did not make it on the flight as the time was given was 5:35 and the flight left at 4:00."
Cons: "I was not given correct information and being a very novice traveller did not check the information."

Pros: "Crew were very caring. Seats were OK"

Pros: "Boarding was easy, crew was pretty friendly and we reached London an hour early which was brilliant."
Cons: "Maybe let us know in advance that there's no TV's in the plane, or meals. Leg room for someone who's 6'4" is non existent, especially when the person in front of you puts their seat back."

Pros: "i was pretty comfortable being in an aisle seat"
Cons: "didn’t love the lights coming on in the middle of the night"

Pros: "The crew was friendly. The flight was safe."
Cons: "The flight to be on time."

Pros: "Neriande (who issued the boarding passes & took checked bags) and her colleague At the check in desk were amazing - actually going behind the scenes to find a gate checked bag that had been wrongly named and was headed for Toronto when we were headed to LONDON GATWICK"
Cons: "Faulty weather radar on a stormy evening cancelled our WestJet PREMIUM ECONOMY flight. After deplaning and waiting for all passengers without checked bags to be rebooked, we eventually were on our way by car from LGA to JFK airport to meet a British Airways ECONOMY flight with only minutes to spare"

Cons: "The food was extremely mediocre for an $18 meal."

Pros: "The over all star rating should have five stars. I mistakenly pressed something and it went to one And I could not figure out how to get it back to five. Everything was on time which I so appreciated."

Pros: "Friendly and helpful staff. Boarded and got off quickly. Clean airplane."
Cons: "I felt cramped in my emergency exit seat, especially having a larger size person sit next to me. My seat was not comfortable. Being tall provides no advantages on westjet. Had to look down at my phone the whole time for entertainment, neck hurt. Wont fly again"

Pros: "Professional, efficient, courteous."

Cons: "Plane seemed older and less leg room for a 6’4” guy. No TVs or monitors to track flight info."

Pros: "The low cost"
Cons: "That which comes with low cost, you get what you pay for"

Cons: "24 hour delay in Calgary because of maintenance problems with the plane. Meant I lost one precious day while visiting my 91 year old mother."

Pros: "Embarkation staff were helpful"
Cons: "No better than AC Rouge which I deplore"

Pros: "Loved WestJet! They are the best airline, always super friendly"

Pros: "Great staff. Fast boarding and deplaning."

Pros: "Crew was friendly."
Cons: "Lack of maintenance. Seats did not recline, seat in front of me was broken. No reading lights available. One washroom became inoperable. Just showing a lack of maintenance or cost saving measures until new planes are delivered. Not a great impression for a carrier striving to compete against Air Canada. I would say they are competing with Air Transat."

Cons: "Big 4 hour delay caused that we missed another flight in London"

Cons: "We couldn't take the flight as Westjet could not get us there on time and would not hold the flight ...... see above"

Pros: "The flight was not cancelled in spite of poor weather"
Cons: "Flight on tarmac for 2 hours after loading passengers no word regularly from pilots or anyone for a long time. Baggage loading and no accountability for huge delays for lost luggage containers? Who is the logistics team? This is not the first time westjet has provided poor service on their international flights. Training if ground staff onsystems is poor. He guest services at tronto openly claimed they did lot know how to operate certain screens for transactions."

Pros: "We survived"
Cons: "On an 8 hour flight there’s no complimentary meal. I paid for a meal and it was worse than free plane food and starved for the rest of the trip. The chairs were horribly uncomfortable with no lower back support and we were not even given pillows and blankets. There was also no free entertainment. I rented a tablet and had it taken away an hour before landing while I was in the middle of a movie. I might have been ok with that if the flight attendant had politely asked for it back rather than rudely waving and pointing while I stared at her blankly trying to figure out what she wanted. Next time I’ll pay a bit more for an airline that respects its passengers and our comfort."

Pros: "I was traveling with my 11 month old daughter and everyone went out of their way to assist us and I didn't feel like a burden to them. When she was sleeping on my lap during the flight they even brought me my meal in portions so I didn't have a huge tray to balance over my baby."
Cons: "Everything was great"

Pros: "Excellent Flight to London"
Cons: "Typical Econofare - pay piece meal for everything including a checked bag."

Pros: "Free upgrade and gate check!"
Cons: "No checked bags or meals for economy passengers"

Cons: "Pre-ordered meals are costlier than those purchased on board. The crew explains it by saying that they give some extra food just before landing, in lieu of that but what they give is too meagre and its not the customers choice."

Pros: "The flight attendants where really nice and so was the service wouldn't change a thing here."
Cons: "I didn't like that someone was reclining in there seat in front of me and it was so far down that it was uncomfortable even to sit in my seat or get to my table. Also was very disappointed that I had to pay for food even though it was way over 8 hours, in the end didn't even bother about food was not much of a choice. Also no TV on this long haul flight was really disappointed again, so I had to pay for a tablet was hugely disappointed. Needed more leg room was cramped on this flight."

Cons: "My ticket/reservation was not found by WestJet. I had to buy a new ticket. Flight Network or Emirates screwed up. I will need you and them to reemburse me. Please investigate."

Pros: "Landed 10 minutes early. Good landing in tough conditions"

Pros: "Very cheerful and friendly crew. Made the journey very enjoyable."
Cons: "Nothing"

Pros: "Basics of chips or pretzels as one food offering"

Pros: "Friendly, polite crew. Well organized boarding"

Pros: "Only problem is my flight didnt have screens and you had to pay for a tablet. I get screens on my flights to Edmonton and Sask for work with Westjet all the time but on a long flight to London they're majorly lacking. A basic meal over a 9.5 hour flight should be included as well."
Cons: "1 for usb charging ports though. I still love Westjet but different priorities for International flights should a no brainer."

Pros: "Helpful polite staff. Many great movies and tv shows to select from."
Cons: "Trying to sleep in an uncomfortable, small, non reclining seat."

Pros: "The flight is decently cheap"
Cons: "Everything else is not really pleasant for a long distance travel. I've never felt more uncomfortable in my life during a flight. But i suppose you get what you paid for."

Pros: "food was good"
Cons: "Delays in connection flight, arrival gate and departure are far away and no help from airlines."

Pros: "the entertainment system was incredible."
Cons: "It was a very long flight-- including a meal in the ticket would have made it more enjoyable."

Pros: "After our horrendous flight to America with Norwegian (never again!!!) it was refreshing to have some space and the staff was friendly"
Cons: "lnternet was very expensive ($4-5 for 30 minutes, so l did not bother) no entertainment whatsoever, but okay for a budget flight during the night"

Pros: "Boarding was quick and easy, and the gate attendant was quite friendly."
Cons: "Very rude crew members; delay leaving YVR. Instead of being honest and upfront about having to leave an HOUR later--and also lying by saying that we'd be flying into Gatwick in only 8.5 hours as opposed to 9.5--they made us wait in our seats while the craft supposedly waited for food to be loaded. The best line was, "Our plane will be landed an hour earlier! But because London doesn't like it when we land early, we're going to wait here for a while on the tarmac so we make it there on time.""

Cons: "You have to download an app to watch movies/tv. There is no food served (transatlantic flight!) unless purchased 48 hours beforehand."

Pros: "Brought our own sandwiches.."
Cons: "We were invited to send our carry iron bags to the hold at the gate. We delivered them to the plane door on the jetway. My wife's bag didn't make it from Edmonton to London Gatwick. That's the last time I send anything to the hold ."

Pros: "Low cost, supportive seating"
Cons: "Meals are extra Arrived a bit early and had to wait about 15 min for someone to attach the gate"

Cons: "Plane needs to be upgraded, don't charge for meals or baggage"

Pros: "Very helpful! Very enjoyable flight, I was worried about my bags fitting as I took a 46L backpacking bag with me but it rit great and staff was so nice!"

Pros: "the price"
Cons: "they left late"

Cons: "Surprised to find out that there was no rock/metal playlist available within music menu, considering that Finnish artists/bands are famous worldwide and very proficient in this genre."

Pros: "the seating was very uncomfortable i barely had any leg room"
Cons: "Dont go on economy its not good espically fir being the main airline for spain its not really that good compared to other airways for example british airways"

Pros: "All"
Cons: "Keep up the same spirit"

Cons: "Plane was 1 hour late and missed my flight."

Cons: "Missed my connecting flight from Helsinki to Miami because the flight from New Delhi, India was delayed by more than 4 hours."

Pros: "Fast connection in Helsinki!"
Cons: "Delay in JFK, old aircrafts and mulfunctioned entertainment equipment."

Pros: "Comfort"
Cons: "Choice of movies"

Cons: "They run out of food choices by the time they got to me."

Pros: "Selection of many movie choices"
Cons: "Late. Late. Always late !! Because there is always delay , missed connecting flight obviously never wait."

Pros: "Plane was clean and overall the service was good. The new terminal and gate at Helsinki are very nice."
Cons: "Boarding was disorganized and chaotic. The seats could have been more comfortable for a tall person. Finnair also likes to nickel and dime."

Cons: "Experience was totally let down by the airport; nothing to blame the aircraft staff though. Avoid Helsinki airport like the plague for stopovers: bad signage, woeful information how to get to the city efficiently in English. HORRIBLE experience when trying to get lost property: you got to PAY for your initial email or pay top dollar just for a stupid and aggravating phone call!!! The number of exclamation marks is not exaggerated here. You can't even ask if they even have the item in their possession. Rarely had such a bad experience at an airport, and I travel a lot for work. This alone makes me think thrice about EVER getting Finnair again. Same company that manages the airport, so I'm giving this flight a bad review."

Pros: "Not having someone sitting next to me, comfortable lie flat beds albeit a bit narrow. Good food when you wanted it, big screen and ok movies, spotless toilets"
Cons: "Nothing really negative to say"

Cons: "Wasn't given vegetarian option for food and don't eat meat."

Pros: "direct flight from Helsinki to Miami was good"
Cons: "Only few movies, announcements were very quiet, the pilot barely spoke English, flight was 2.5 hours late."

Pros: "This was a very short flight and I don't recall if there was any food service or entertainment."

Pros: "Friendly service, lots of movies, Marimekko design."
Cons: "Seats too close together front to back. If the person in front of you lies down the back of their seat is in your face."

Pros: "Very comfortable"

Cons: "This flight was delayed 5 and a half hours and did not arrive into Chicago until almost midnight."

Cons: "Plane too old for such a long flight"

Pros: "The crew made the entertainment free because of the delay. They were very hard working to make things right."
Cons: "Plane was late at Fenver and Heathrow and into Geneva. Plane seating was uncomfortable for such a long flight. This is an airline issue not specifically BA/Finnair."

Pros: "British airways offers amazing entertainment selections on the Screens over 25, food was good"
Cons: "Check in line was terrible, I had checked in online but still waited over a hour to bag drop, service was not great either the flight attendants were not happy at thier job.."

Cons: "I wanted to go home early..... They wanted to charge me 400 dollars to change my booking"

Cons: "American Airlines charged me 100.00 dollars for 1 extra luggage, ridiculous! !!!! Also we took off 1 hour late without any notice..... Flight to Europe with AA sucks..."

Cons: "The movies did not play on my screen. I tried to use the screen on the seat next to me and the movies quit in the middle. It was very annoying."

Cons: "I sat in the window seat. Trying to get out of the row is very difficult. The arm rests do not rise high enough to get around without needing to climb over them."

Pros: "Good flight, really good new A380 aircraft, smooth nearly all the way, usual small seating space as on All airlines"
Cons: "Routine airline food."

Pros: "The fact that I got home in one piece I really like."
Cons: "Planes are old, small tv screens in aisles, older seats and headrests. I had requested Gluten Free meals and on the way to Amsterdam they did okay (besides the snacks). On the way back they didn't even offer me the second meal GF, I had to ask another flight attendant who went looking for it and found one.. so it was there, they just hadn't bothered to look for it. I also never understand why you wouldn't start boarding with the last rows? Is that just me? The aisles are always so crowded when the last rows walk in and there's always a line."

Pros: "Crewmembers were professional and nice!"
Cons: "Snack and meal were not so tasty, and the descending before landing was really uncomfortable."

Pros: "customer service was attentive smart yet caring."

Pros: "The fact that this is the only daytime flight from Boston to Europe."
Cons: "Food was very ordinary, and drink choices may have been theoretically available but the crew did not offer the choices."

Pros: "The flight was operated by Iberia. The crew was very good, the flight was on time and it was a comfortable flight. It was not a full flight (either way to or from Madrid) and there was plenty of room to spread out and sleep which was nice. The entertainment system was great with many options from TV to movies to games and music. The food was only fair but included a meal and a large snack. I will definitely take this flight again."
Cons: "nothing to dislike about the experience"

Pros: "Service was great"

Pros: "Crew, boarding, cleanliness of the plan, and all other aspects other than food were good/excellent."
Cons: "The vegetables in the meal / salad were still frozen….inedible. In the morning in the asian vegetarian meal it was simply fruit…that was it. No protein source. I have been on many BA flights and the food has not been this poor, so not sure if the carrier who services food source has changed."

Cons: "It is absolutely ridiculous that they made us pay $100 each way for our ski bag/equipment. I will never fly either airline again. Horrible customer service as well. The airplane and its entertainment system is quite antiquated and needs to be updated. Horrible experience."

Pros: "Everything was top class!"

Pros: "For the first time ever I had a flight on British Airways where I did not feel like I wanted to choke somebody at the end of the flight - so I was pleasantly surprised at this particular BA flight."
Cons: "BA gates in NYC are abysmal - the entire terminal is... Why are the restaurants advertising being open to some specific time (well prior to the departure of this flight) yet then have staff holler at you that they are closed when you try to go in well before that time. It would have been very nice to have been able to sit down and have some dinner prior to the flight, but the rudeness of both of the two restaurants and their staff was worthy of the notoriety of NYC attitudes (which I don't generally see in mainstream NYC society)."

Pros: "The flight was on time and all went as planned"
Cons: "The in flight service was average"

Pros: "Not much."
Cons: "The flight was delayed about 5 hours due to reasons no one really seemed to understand. Food was pretty bad as well."

Pros: "I am not sure why when i bought my ticket on kayak just fly was the company I had to deal with. They are extortionist. They should be deleted from your website."
Cons: "Tried to change my flight, line got disconnected, when I called back the fees went from 500 to 1100 - they couldn't justify why. I will never use kayak again if these kind of people is who I have to deal with coupled with awful customer service they hung up on me three times."

Pros: "Checking was a breeze and there were no hassles getting through security. The flight was great and they even had a vegetarian option for my meal! I would highly recommend to anyone for International flight!"

Pros: "Courtesy of attendants, smooth flight, good service"
Cons: "Food and your TV screens are not good. Very hard to operate a touch system which is so insensitive. Movie choice rather poor as well"

Pros: "It was a wonder flight. Great staff!!! highly recommended."

Pros: "The crew was friendlier than on the other airlines we took on our trip. The seats were cramped (coming from someone average height) and the middle and window seats have a combined under the seat compartment so you don't feel like you have personal space. I wish the breakfast was more substantial, but other than that it was a wonderful flight and I would definitely take it again!"

Pros: "The food and Cava were excellent. So were the friendly staff."
Cons: "Seats slightly too small, but thankfully not as bad as American Airlines on the way over: that was horrible!"

Pros: "on time, rather efficient process, cabin crew"
Cons: "not much room in economy, ipads are not ideal"

Cons: "When I got to Phl I missed my connection to London. No one seemed to care that I needed to be in England by the 18th. They kept retorting me to arrive in England on the 19th. I told them multiple times Id be flexible and go to any city in the UK just for them to get me there on the 18th. The First person I talked to said it was impossible. So I called again and talked to another person and all of a sudden it was possible. The worst part was they sent me to Boston after that I didn't get to Boston until 1:50 am and they did not compensate with hotel or anything while my flight to London was not until 8:00 am the next morning. So I spent the night in the airport. Oh and then when I finally got to London, my bag is lost and they told me I'd have it by tomorrow and I still do not have my bag and have called and they said they can't tell me anything."

Pros: "Aircraft was so old.Paying $1,000 for that, when any other airline uses decent aircrafts, is just unacceptable."

Pros: "Short good flight, with no issues. Friendly crew that were very professional."
Cons: "No complaints."

Pros: "A Good Deal,but when.we arrived in Miami there was not any finner counter,when to BA anf6 then we found the flight"

Cons: "Delayed 5+ hours. Aircraft was changed to a smaller plane than we booked."

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."

Cons: "Landing was terrible ."

Pros: "I'm writing this from a coffee shop in Reykjavik right now, on my layover on the way to Norway. So far, GREAT experience."
Cons: "This is a Denver airport thing, not Icelandair, but they made us take our snacks out at security. WHAT?"

Cons: "Flight attendants did not offer food at any price. Food or drink (except water) is not provided on a 7 hour flight. Conflicting information on 2nd bag. Some said free on international flights. Had to pay $95 for 2nd bag at airport. Legalized theft."

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."

Pros: "Free movies"
Cons: "Not enough overhead bin space, no food, only a small drink"

Pros: "I liked how small the airport was in Iceland no freaking out when your plane lands and your connection is already boarding"
Cons: "There was no meal provided which was a bit of a surprise for an international flight.."

Pros: "Clean aircraft. Friendly staff."
Cons: "short connection in Iceland are nice, but can be stressful... I got off the plane, into the terminal and it already said last call for the flight I was. Running through terminal... arriving at gate, and there we waited for other passengers another 20 minutes or so. It is comforting that they wait, but the running and worrying was not that nice."

Pros: "Iceland air has a good selection of entertainment and all the complimentary water you can drink. That is about the only good thing I can say about my flight."
Cons: "Never got a meal or even a snack on an 8 hour international flight. Seats were very uncomfortable. We took off late, connected late and you guessed it landed late. Nothing is free or complimentary with Icelandair. You get what you pay for. I hope my return flight will be better!"

Pros: "On board entertainment was good (i.e., movies, shows, etc.)"
Cons: "No food was served."

Pros: "The flight was fine, the crew was great. The only issue was it took almost 2 hours for our luggage to come out at Heathrow, the entire flight was waiting and there was no one from Icelandair to ask to neither did they send anyone to tell what the delay was."

Pros: "The Aurora lights on the overhead compartments was a pleasant touch."

Pros: "The crew, amenities, and service were great!"
Cons: "Didn't enjoy having to be transported to the train by bus in Reykjavik, since there wasn't a jet bridge connecting the departure level of the terminal to the plane."

Pros: "Very comfortable seat in row 5"

Pros: "Good crew, plane and flight all around. I have no complaints about the actual flight."
Cons: "When boarding, no announcements were made. One moment I was waiting to hear when we would be boarding, then next thing I know there is a mile long line at the gate. Very weird."

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."

Pros: "Flight took off over an hour late even though everybody boarded and the doors were closed well before our scheduled time. This caused me to miss my connecting flight and I was rerouted. Overall, it took me an extra 9 hours to reach my destination."

Pros: "Nice flight attendants"
Cons: "No food provided for an international flight. Entertainment system did not work making the long flight seem even longer."

Pros: "Same as above."
Cons: "Nothing, I enjoyed the flight."

Pros: "Smooth Flight"
Cons: "Did not get the seating as portrayed on Icelandair website.We were seated in 2 tight seats abreast next to window. Food selection was limited to a baguette with one thin slice of ham. However, my motivation to pay up for economy comfort was for the seats. I will be seeking a credit."

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: "I'm flying to Munich using Icelandair. The connection at KEF was only 45 min but there was a passport control, and huge lines there. By the time I got to the person who's checking my passport, it's already the departure time. I thought I would miss the flight for sure, but obviously they handle this everyday, and waited for those coming for connections."
Cons: "The 7-8 hour flight has no food at all. You have to pay to get a small snack. I'm used to these types of airlines flying domestic, but this was the first time that an international flight was like that. Well, next time I'll prepare more."

Cons: "Movie selection"

Pros: "Loved the Saga Lounge - that was a great treat for us, as we were unaware that it was available to comfort economy passengers until we were informed at check in."

Pros: "Peaceful and smooth until the landing."
Cons: "Landing quite rough."

Pros: "On time"
Cons: "No food or drink amenities"

Pros: "Very pleasant crew."
Cons: "1 of my bags was delayed accidentally."

Pros: "Clean and roomy flight! Good service."
Cons: "No snacks or drinks was surprised about this on an international flight."

Cons: "For the cost of this flight, I was very disappointed. I still can't believe that on a flight from Denver to Munich there would be no meal or even snack provided. Also, my TV did not work, so I did not have entertainment on the flight. The flight attendant told me he would look for an iPad several times and came back one hour later to tell me they didn't have anything. My husband sat right next to me and was very uncomfortable because his seat didn't go back. Overall, a very disappointing flight for $1400."

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."

Pros: "Entertainment options, crew was very polite and helpful"
Cons: "Any overnight flight should provide a meal or better meal options to buy"

Cons: "Beverage and food service was poor. Didn't like the fact that there was no tunnel loading in Reykjavik."

Cons: "Arrived 10 hours late, lost luggage."

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: "Nothing really wrong."
Cons: "Pay for food/drinks on international flight"

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: "-This was the first time flying with Icelandair and will definately fly with you again. Hot coffee was very good and so was the Yogart."
Cons: "Not having a meal available. Next time I will know to pack a sandwich."

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: "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."

Pros: "Huge snowstorm in Denver caused the airport to shut down. Plane left about 5 hours late. We missed our connection and even though it wasn't Icelandic Air's fault they gave me a taxi, a room and three meals until I caught my connecting flight the next day. Amazing service."

Cons: "Crew was rude. No meal on an international flight. Usb charger wouldn't work."

Pros: "Seats were hard. I flew this airline 7 years ago and was so disappointed to see all the cut corners. I loved the old blankets and the seats were comfortable."

Cons: "Definitely a surprise that they don't serve any food on a transatlantic flight, but that's that. At least they allow you to purchase food."

Pros: "Good entertainment system"
Cons: "No food provided other than for money Rude staff Ill-disciplined children running rampant, with no consideration for other passengers."

Pros: "Flight was fine."
Cons: "Crew was not very friendly."

Pros: "Crew was friendly, food was good"
Cons: "Entertainment was broken in one of our seats, the seats were not comfortable"

Cons: "We went to Gatwick(75.00 Uber) to reschedule in person and we were told there were no refunds and if we wanted to change it would be 250 pounds. It is my wife’s and my 35 year anniversary and this wants a mood dampener"

Pros: "Pilot was friendly and addressed the crew and passengers multiple times with updates."

Pros: "Nothing really"
Cons: "Politeness during check-in, timeliness in providing gate information, having a person at the BA desk to help, being on time"

Pros: "The seats were comfortable"
Cons: "Everything was ok"

Pros: "I arrived safe and sound"
Cons: "Even though I purchased an exit row seat we were packed in like sardines. I know airlines have to make money but that flight was ridiculous. also, the plane was way too warm for much of the flight. Not sure if there was a problem with the air but for these prices...fix it please."

Cons: "One piece of luggage was left at Heathrow. It arrived on the next flight so it turned out ok but was stressful for an hour."

Pros: "Service is good, people are friendly. Efficient. Keep you up to date with changes."
Cons: "No complimentary beverages. Not even water. Baggage did not make it."

Pros: "The seat was fine. the flight was as expected."
Cons: "expectation that one will fly with only one carry-on bag and not receive any food or beverage during the flight. industry trend is ridiculous ..."

Pros: "Simple. Arrived (late) to my destination(s) in one piece. Pleasant flight crew."
Cons: "Expected more for my money...In flight services (movies) screens were very small and hard to see. No charging outlets for phones. Flights were delayed. No sense of urgency mentality? (Don’t get me started on the London airport experience)."

Pros: "The crew was friendly."
Cons: "The flight was over two hours late. No USB ports for electronics. Leg room and seats were dismal."

Pros: "it was very clean on a board."
Cons: "even water for money"

Pros: "The seat was comfortable and featured the good headrests."
Cons: "Food was inedible so I left it. The sound on the movies was tinny making hearing difficult."

Pros: "The plane wasn't full, so there was an empty seat in-between my aisle and their window, as well as open spots throughout the plane."
Cons: "Plane was delayed several times. Website wasn't clear about what time to show up to the airport. Food was served late and was mediocre."

Cons: "Left late. Everything was unorganized."

Pros: "Crew were exceptional in service friendliness and attentiveness."

Pros: "i got there alive."
Cons: "narrow seats, no legroom, small entertainment screens, OK food (but they are British, so not much expectation), then no gangway off the plane, we had to wait a long time for the stairs, then everyone down the stairs onto a bus. staff was friendly enough, but once they fed us and one round of drinks, they were gone until they rushed us thru breakfast (no coffee refills). good thing the flight was cheap!"

Pros: "Food was delicious and out flight attendant was very helpful. Plane was quiet and the movie options were good."
Cons: "Plane was honestly very dirty. There was a ton of crumbs and gross stuff in th seat back pocket. Which I did not even use because I didn't want any of my things to touch. The overhead lights were covered in dust. So make sure you have some some type of cleaning wipes with you!! I do understand that I was flying economy, but that doesn't mean nothing should be cleaned."

Pros: "First time we upgraded to Business Class. It was fabulous compared to the cattle car we usually fine in/"
Cons: "none"

Cons: "security in Heathrow was AWFUL. There was only ONE person working to screen luggage AND check luggage that was questionable. There wee 15 people waiting for luggage who almost missed their connections. I sprinted through the airport and made my connection with 2 minutes to spare."

Pros: "Very courteous attendants"
Cons: "All good"

Cons: "Crew seemed to be "just getting through their day" simply going through the motions."

Pros: "Service was great - so polite and friendly. And the coffee was worth every penny."
Cons: "the luggage fee - Now I understand why the fare was so inexpensive! I'm an American and thus slow :-)"

Cons: "food was not good."

Pros: "Luggage delayed."

Pros: "I loved the legroom in the emergency seat I had and the service was top notch. The food and food choices was also really nice and the wine served with dinner was great."
Cons: "Overall loved my emergency row seat the only negative for my particular seat was once the rest of my row was filled in and the 2 seats in front of me it made it impossible to get out of the seat and stand up unless I could had the person sitting in front of me get out of his seat."

Cons: "Did not get the seats I paid for"

Pros: "Was not made aware of baggage policy. Their regular policy allows one checked baggage but not our ticket. Was not prompted when doing online check in and led to me paying almost 200 pounds for luggage. Just ridiculous!"
Cons: "Baggage policy not clear - good way to force customers to pay more and help their revenue!"

Pros: "Boarding was straight forward with the automated scanning of boarding pass."
Cons: "I was totally taken aback that I had to pay for tea and coffee. After having to pay for baggage and to reserve my seat for the flight. At least beverages could have been offered at no additional cost. Very disappointed with BA."

Pros: "Wine with dinner."
Cons: "No tv for 9hr flight. Breakfast was awful."

Pros: "No turbulence!!!"

Pros: "For economy class it was good seats (bulkhead), the crew were nice, and the food was good."
Cons: "The tiny screens for movies were awful. Worst of all, the horribly loud voices that nearly break eardrums when the crew comes on during the flight was both painful and annoying."

Pros: "The flight was not very full, so we could spread out. Normally I really like British Airways, but the lack of AC was difficult."
Cons: "The air conditioning did not work and it was very warm, 77 degrees at least, the whole flight. It made it very uncomfortable. They said something was broken."

Pros: "On time, friendly crew and decent food. Price also good"
Cons: "20 year old plane with tiny entertainment screens. Old and uncomfortable seats, especially for a long flight. Can't believe we were at a remote parking position inbound and outbound at LHR..."

Pros: "It all went smoothly and was on time"

Pros: "Nothing"
Cons: "I arrived about 45 mins before the departure time and they refused to let my 85 year old sick dad in a wheel chair board. They did not assist him in rebooking and we had to sleep in the airport to catch an Easy jet in the morning as all hotels were fully booked. This is about the worst service I have ever encountered and I would like a full refund Thanks Charles"

Pros: "Slept most of the way. Cabin looked new, so that was nice."
Cons: "Having to gate check my bag even though it fit in the overhead bin."

Cons: "Did not like that I thought it was a BA flight but was really a EI flight , which means I had to get a boarding pass but I was sure was on BA and almost went to there booking counter to get boarding pass."

Pros: "ALL the cabin crew were excellent! Polite and helpful and cared for the comfort of all their passengers."

Pros: "Nothing. At. All."
Cons: "This was a nightmare. BA had no flights available to Edinburgh. Booked on 3 separate flights at 2 different airports. Last one was canceled outright. After being awake for 28 hours and traveling for 15, we finally were given a hotel room for the night in London. Still trying to get to Edinburgh."

Pros: "Nothing in particular"
Cons: "Sprang for business class. Could not get assigned seats until 24 hours before takeoff unless I paid an extra $200 and therefore got the last 2 seats together. Check in was very slow. The agents disappeared for about 15 minutes. Business class lounge ran out of food but BA gave us vouchers to eat elsewhere in the terminal. Flight left about an 90 min late (seems like it is always late) so had to run through Heathrow to catch the connection. Boarding area was too small and chaotic. Seating in business class was ok for me as I am only 5''7" but would be poor for someone over 6 feet. The steak entree was brown through and through. Overall the experience was disappointing."

Cons: "Lost luggage"

Pros: "Everything was fine."

Pros: "Short"
Cons: "No entertainment or USB or power for charging"

Pros: "When the flight was delayed and I missed my connection, the crew had a new ticket for me by the time we landed."

Pros: "On time with good adult beverages. Had good movie selection as well."
Cons: "Nothing"

Cons: "The only issue we had with our travels in London had to do with the Heathrow Intl Airport. We were unaware that we would be required to go through security again. This held us up and almost made us miss our connecting flight."

Pros: "Comfortable seats"

Pros: "The flight attendants"
Cons: "Couldn't book my seats 24 hours ahead. Couldn't book my seat on check-in for 2nd flight. Put in middle seat for 1st flight. Put on standby for 2nd flight. Very stressful"
