Cons: "The airline changed a seat reservation after I paid for it. The Swiss support staff told me on the phone they would call me back. They never called back. I called again and was told the seats are changed and I can’t do anything anymore. The return flight seats also disappeared from the reservation. I had also paid for it. The support staff when I called again put back the seats for my return flight. I tried to check in online. Not working. Tried at least 50 times. Not working. Called the support staff. They told me to call the check in support center. I called the check in support center at least 50 times where mi was told the staff are busy and could not answer the call. I called at 6:00am next day where I was told by the check in support staff that my ticket had an issue which they did not know exactly what was the issue but prevented me to do a check in. I drove more than 2 hours to the airport where finally I could check in but I was told that my return flight seats had disappeared again. They managed to put them back again. I hope this time it’s finally ok. The support staff on the phone told me I could get reimbursed for the seat reservation I had paid for for the on going flight. The Swiss staff at the airport told me there would be no refund. Swiss is terrible"

Cons: "I am a frequent flyer with swiss airline. Amazing crew, boarding, taking off and landing is on time if not a little earlier. However, I was quite disappointed with the enertainment package and food."
Pros: "It was an 8.5 hour flight and we got fed 2 meals, 2 snacks and had lots of beverage breaks! We were delayed a little but it was due to an issue in France, not anything to do with the airplane, and the captain found a solution faster than he had originally said he would (with the help of the tower of course)."
Cons: "The legroom in economy is just as bad as you would expect."
Pros: "Plane on time, crew friendly. Great flight!"
Cons: "I did not like they were so strict with the carry on luggage and stopped us at the TSA"
Pros: "The flight attendants were extremely polite . Great service i love my accommodation in Business class . Very clean , punctual, comfortable, up dates by pilot frequently. Over all a hard work TEAM of Flight Attendants. Thank You to all of them."

Cons: "N/A"
Pros: "Short flight.."
Cons: "They gave me and the 2 other black people who were flying, the seats all the way in the back. I'm never telling the people at check in "just give me any seat" ever again! It was so obvious I almost complained to all the attendants! I just tried to keep my cool... HORRIBLE FIRST EXPERIENCE TO EUROPE!"
Pros: "The flight had a delay but managed to (partially) make up for it."
Cons: "Boarding was a little slow. Perhaps it would be nice to more explicitly explain to people how to more quickly stow their luggage and then sit down in order to let other people through. The seats felt a little more cramped than usual."
Pros: "Clean and efficient plane, crew and procedures."
Cons: "In order to board we were requested to line up at gate according to seating group. And then had to wait there in line standing for almost 45 minutes before we were finally told we could proceed to board. No reason for lining up so far ahead of time....and had to stand....."
Cons: "They charge you an extra $ 100 DOLLARS FOR THE OPTION TO PICK YOUR SEAT AND WHEN YOU CHECK IN THEY SAY THAT IT WAS JUST TO SIT IN THAT SECTION OF THE PLANE. WE PICKED OUR SEATS BY THE FRONT BULKHEAD AND WHEN WE CHECKED IN THEY REFUSED TO GIVE US THOSE SEATS BECAUSE THEY SAID OTHER PEOPLE PAID MORE THAN US TO HAVE THEM. THEY SHOULD BE INVESTIGATED FOR THIS KIND OF FRAUDULENT ACTIVITY."

Pros: "Comfortable business class seats, much better than the updated Lufthansa footsie leg rests. Attentive staff. Puzzles for the children"

Pros: "The staff was wonderful Pleasant, quick with requests , very professional"
Cons: "I get motion sickness and found it strange they no bags were in the magazine pocket. Had to ask for it and wait"

Cons: "Same situation with the food. I was given Molley's special food. Then I was given a cold croissant. That was it. Lufthansa gives little sandwiches."
Pros: "smooth ride ... long :( ... but smooth and clean ... thank you for having a flight directly into tampa ... female copilot? really? :) wow, great job!"

On time and good staff. Excellent

Cons: "Seats can be better."
Cons: "Flight late more than 3-4 hours on Frankfurt. So upset. I will never and ever try with Frankfurt again. I bought shortest way ticket to pay more money but unfortunately flight late about 3-4 hours. Money trap. I would love to have another free flight or I will post the tickets on facebook, Twitter and etc... To make a terrible flight reputation."

Cons: "Food was OK, could have been better."
Pros: "Good leg room in aircraft and comfortable seating."
Cons: "My checkedin baggage did not reach the final destination and was delayed by 24 hours. Further, when my baggage did reach, one suitcase was damaged. Did not expect this from Luftansa."

Pros: "Great service. everything was on time, or early. overall pleasant experience."
Pros: "Visa for India was not checked in Denver. Landed in Frankfurt and discovered that the visa was expired. Stuck in Frankfurt for 3 nights until new visa was issued. No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags. Bags finally arrived on Monday at 9AM Without clothes, toiletries and medications for 6 nights. Now I am delayed and will probably have to pay rebuke and fare change to extend my stay here."
Pros: "Lufthansa is extremely efficient, and the staff is very helpful all while being cheerful and kind. The planes are new and clean, everything was a notch above typical economy carriers. Well done!"
Pros: "1 hor 30 minutes instead of 2 hours 15"
Cons: "Worst food ever, and zero entertainment"
Pros: "Anna, she was the supervisor at the check in desk at Denver airport. She was super helpful and very nice. She went above and beyond to help me out with the issue i had... but everyone else i went to get help from were not at all helpful (3 other people), sour face, they probably hate their job. Movie choices on flight to Munich were great. Smooth flight, I didn't lose my bag so that was great too!"
Cons: "Rude crew member. One bad apple ruins the whole bunch. I pre selected my sest at check in on line but got different seat. Not sure why but that was uncalled for. Boarding was 35 minutes late because flight arrived late also. The lady that boarded us was nice and funny."
Pros: "Crew was excellent. Plane was very clean."
Cons: "Seats in economy are miserably uncomfortable especially for a flight of this many hours."
Pros: "I liked that if I asked for something the crew would get to me rapidly. Extra leg room."
Cons: "Boarding process: just a lot of confusion. Inflight crew service poor: the was no time to have any brain reaction when they would pass by with coffee or anything...and when I asked for coffee the answer for a gentlemen of the crew was: coffee already passed by. Really!!?? Make sure that +$1200 are spent well. Rude or inattentive crew members shouldn’t be on flights that are that long...I had to nsist to have a miserable cup of coffee. Movie selection was poor. USB port didn’t work. Shame on you!"
Pros: "At least Lufthansa has a little bit more leg room."
Pros: "The best in-flight service I have ever had on the Lufthansa flight from Denver to Munic!"
Cons: "Couldn't reserve a seat, even 24 hours in advance because web checkin was turned off. Ended up in the middle of the middle on both directions."

Pros: "Timely."
Cons: "Seats are small, no entertainment, food was below average."
Pros: "the crew are exellent"
Cons: "Entertainment options were not too good. The flight should have more American sitcoms and more Hindi options."
Pros: "The entire experience was great. Easy check-in, boarding, on time, friendly service, good food, good movies, and overall a really nice atmosphere for such a long flight. Would recommend this Flight to anyone."
Cons: "Nothing"
Pros: "The overall feeling of this flight was 'relaxed'...after getting over the fact, that this was a huge (two story) airplane. Short flight from Denver to Frankfurt...only 8 hours:)"
Cons: "I would have loved to be offered eye shades and ear plus, since most passengers watched movies and i wanted to sleep:)."
Pros: "Flight was on time comfortable good crew clean and upbeat"
Cons: "Boarding"
Pros: "Great service, crew attentiveness and economy comfort. Movie and music selection was good."
Cons: "Slightly larger food portion"
Pros: "Good flight good seats smooth ride."
Cons: "Boarding was not organized."

Pros: "United is a good partner to Lufthansa. I like United. It was a quick flight, but a good one."
Pros: "Nice crew"
Cons: "Lack of leg room!!! After my bicycle box was inspected they failed to secure my bike the way I had it in the box. Bike was flipping around in box. Bent rear brake calipers. Bent brake hoods. Rear skewers were uncoupled. No way to treat a $10,000 bike! Very upset!"
Pros: "Pleasant crew."
Cons: "Annoying kids in seats behind us :( Not enough leg room for someone over 6 feet tall."
Pros: "Disappointed overall. United Airlines took over here and you could immediately tell the difference."
Cons: "Seats were uncomfortable, no food only snack which is typically crushed pretzels. I typically never fly United because of their service, food etc very poor"
Pros: "I've flown on many different airlines since I was 10 years old and hands down this Lufthansa flight was the best and smoothest flight I have ever experienced. First of all, the plane was very comfortable and had good leg room. The flight staff were all extremely courteous and attentive. There was one point where I was reading in the dark and the crew member asked if I wanted the light turned on to read! Normally I don't sleep on flights, and the same crew member asked if I wanted ice cream since I don't feel like sleeping. The crew seemed to have this magic ability to make the flight more comfortable without the passenger having to even think about it, or try to ask for extra service. All of the crew were just very outstanding and organized throughout the entire flight, they were all generally very helpful and kind. By the time I got off the 14 hour flight, I didn't feel even the slightest bit tired or anxious, I was able to spend time with my friends in Budapest upon landing and stay out till 2 am without having to sleep or rest because the flight was so good."
Pros: "The flight was on-time!"
Cons: "The food was mediocre."
Cons: "Rude (American) passengers not keeping the "curtain down", when it was time to rest, and being very chatty. Also baby crying, but this is inevitable, it happened to all of us, when we had small babies."
Pros: "Great crew members, service, and flight."
Cons: "Seat (43A) in economy class in Airbus 330 is not great for oversea flight unlike I flew in LH 747-400 in the past, it does not fit 6+ ft tall people. I could not stretch my legs at all. My knee keep hitting next seat at front of me. Hello Lufthansa, are you listening?"
Pros: "The food was very good. The service, the preciseness."
Cons: "I didn't like the entertainment, there should me more options for movies in English and Arabic."
Cons: "They cancelled the flight and did not help at all for rescheduling."
Pros: "Seats had extra legroom which was very nice."
Cons: "Screens were on by default and hard to figure out how to turn off. Ads are very annoying."
Cons: "lastminute.com was completely unhelpful in assisting with any changes to my itinerary. They repeatedly provided me with incorrect information that sent me on a wild goose chase."
Cons: "Boarding tool a long time and late take off"
Pros: "Stewards dis perfect job"
Cons: "Everything"
Cons: "Austrian could learn from the likes of singapore airlines and cathay pacific: the choice of movies was pretty limited (1 italian, 1 french, 1 spanish) and the games were simply boring. The food was ok, breakfast pretty terrible (breed but no butter, reconstructiesergramingtheworstieverate.Stodwoowfs"
Pros: "Everything about the United Airlines portion of the trip was terrific: lots of food & drinks; good entertainment system; good seats even in economy. United really stepped up their game."
Cons: "The seats on the Austria Airlines portion of the trip were very close together & very minimally structured (little padding, depth etc.)"
Cons: "Seat spacing"
Pros: "In flight crew worked hard"
Cons: "No lines for boarding - it was a mess And randomly we were asked to check in our bags though Austrian crew had earlier tagged them for carry on"
Pros: "The hotel was nice although I was unable to sleep due to the delays all around concerning my connecting flight. I am thoroughly upset because I contacted the airlines 3 times in May to express my concern with the 30mins layover. And to no avail. My worst concerns are being played out now. It appears that their isn’t any concern from the airlines about this catastrophe impacting so many people. Shame on you."
Cons: "The connecting flight departed before the first flight landed. Then I was given the wrong information of gate departure by airport personnel. After running like crazy to find this gate for departure, the plane had already departed before we even landed. There wasn’t anyone around to help, and finally I found an airport worker who gave me the same incorrect information. She was as perplexed as was I. Finally, she directed me to the information booth where I was booked in a flight the next day. The food voucher was insufficient to cover dinner, i had to pay out of my pocket but I was frugal given the financial situation. The taxi service personnel were rude and it took a long time to taxi me to the hotel where I am unable to sleep because I have an early morning g departure. All in all, between the airport delays getting me to the hotel, lack of proper food and treatment by personnel, I am exhausted and lost sleep in the process."
Cons: "The food was so cheap... pasta and a muffin. I’ll be looking around for another airline."
Pros: "Good"
Pros: "Great to be able to check in bags at the CAT railway station in the morning. Cabin crew were excellent- very friendly and helpful and did two drinks services. Austrian’s cabin crew sets them apart on European routes."
Cons: "Food"
Pros: "Decent amount of space between seats"
Pros: "Landing was a disaster"
Pros: "I get Airpoints with the flight, crew were lovely."
Cons: "Flight was overbooked, so a few delays (as they were asking if anyone would layover to release a seat) and they were being very strict on the one bag per traveller, but that’s fair enough considering it was busy."
Pros: "Polite crew. The food was much better that on any airline these days. The boarding process was organized fine."
Cons: "As on any airline these days the leg space in economy class is very limited. The movie selection was OK but not great."
Cons: "Caótica boarding Uncomfortable seats did not recline"
Pros: "We had a very tight connection but there was no problem. With only 30 minutes between arrival and departure our checked bags still made the flight."
Cons: "Poor announcements"
Pros: "Flight attendants were extremely friendly and considerate of passenger needs. In flight Wi-Fi is free in economy. Good leg space between the rows. Overall it's rare to find such good service now a days."
Cons: "While going to the gate G11 at Vienna airprt, i slipped infront of the gate in presence of 3 male austrian airways staff who were checking there. After i got up i requested if i could get some water and they said they cannot. Finally a co passenger gave me her bottle of water. I ended up actually breaking my leg"
Pros: "too short to tell."
Cons: "Not applicable"
Pros: "Not much"
Cons: "Lateness and virtually no food at lunchtime"
Pros: "The flight was nowhere near full, which was terrific. The crew were excellent, polite and attentive. Everything was on time."
Cons: "I don't remember anything about the food."
Pros: "crew"
Pros: "The plane was comfortable and clean. Internet was offered"
Cons: "The Internet didn't work. Although boarding was good the person making the announcements needs to know she should speak up."
Cons: "Complete lack of information and abrupt staff when flight was delayed"
Pros: "Boarding was easy. We took off a bit late, but landed on time. Staff was responsive."
Cons: "Mediocre breakfast. Entertainment wasn't great."
Pros: "Efficient crew, good meals,on time arrival."
Cons: "Took a while to board and could use more updated films-minor details."
Pros: "Even though I was very disappointed at what the Austrian airline did to me, the staff and crew and captains where professional and the flight was comfortable especially on Lufthansa. However, I missed the experience of enjoying the flight with the group of people that I joined on the way to Vienna and to Egypt."
Cons: "I didn't like the fact that they cancelled my Austrian flight to a completely different company (Lufthansa). I paid extra money when I reserved the tickets in the USA to make sure I am on the same plane as the other three families that i wanted to be with as a group. They had reserved their tickets and I got the flight numbers and when I reserved my booking I paid extra to be on the same airplane as the rest of the group. My plan worked going to Vienna and to Cairo (although one of the planes were delayed 3 hours which ruined our stay in Vienna) but on the way back from Cairo to LA, I couldn't be with the group because I left 2 hours early and arrived in LA 2 hours late. I pleaded that I came with a group but they said I have a different booking so they couldn't honor keeping me on the same plane as the group. I am very disappointed and will avoid my future travel with Austrian airline"
Cons: "When I was boarding all representatives was very unfriendly and I would say they were rude."
Pros: "Great staff, friendly and helpful."
Pros: "Crew friendliness."
Cons: "As I was flying from London Heathrow back to Vienna, I had a carry-on that was allowed on my flight with Austrian from Vienna to London. My carry-on weighed 8 kg, like is required by the rules. While boarding my flight, the woman at the counter told me my bag had to be checked because there were too many carry-ons on the flight. I asked her that I keep my bag because I had medication in there, and she didn't listen to me at all. She just kept repeating that i have to check my bag, and then took my bag from me and gave it to the baggage crew there. I didn't want to make a huge scene because the flight is only 2 hours and I hoped i Could deal without my medication during that time, but I found it incredibly, incredibly rude and awful to not listen to a passenger."
Pros: "Pleasant flight crews on all flights."
Cons: "Cramped seating in coach."
Pros: "in this case, nothing"
Cons: "1.15h delay - sitting in full air craft without aircondition cold, not profi behavior no please, no sorry, no "what would you like..." none nice word"
Cons: "I could not pay for check-in baggages when I bough 4 tickets for 4 passengers. So I called the airline customer service, and they told me that the first check-in baggage is free. However, when we boarded the airplane on 9/5/2016, we were charged 30 Euros for each bag, a total of 120 Euros for 4 checked in bags of 4 passengers. This is unfair, and I would like it to be corrected if possible. Thanks."
Cons: "At 11h30 of 14/9 we (HOANG MINH CHAU and NGUYEN SI THANH) were standing at the ticket counter in Vienna and we could not check in due to no payment yet for the ticket and so the reservation has been cancelled. Due to this reason we had have to buy new tickets at the airport ticketing counter. So please sort out your problem with the airline and get back to me. From my bank the payment has been done yet to you. We had have double pay for one trip."
Pros: "The check- in experience was simple and the seat entertainment system was excellent!"
Cons: "Unfortunately, like any economy class seating, wider seats and more recline ability would be nice."
Pros: "Service was spectacular. The United crew was awesome."
Pros: "Everything seemed all right"
Cons: "One of the flight attendants had an attitude problem, which put a wrench in my otherwise pleasant flight."
Pros: "The meal and drink service was quite good. The stewards/stewardesses were very attentive and kind."
Cons: "There is not enough leg room. There is even less room if the person in front of one's seat has the seat reclined. The seats barely recline at all, so sleep is impossible. Sleep would be possible if there were enough room to rest one's head on the tray in front of the seat. This is impossible if the person in front of one's seat has reclined his or her seat. Thus, sleep is totally impossible on this aircraft. The sinks in the bathrooms also need to be deeper and need to drain more quickly."
Cons: "Seats in economy class were crammed with next to no leg room"
Pros: "The only positive aspect about this experience was the crew on board the plane. They were pleasant and efficient."
Cons: "The true cost of this ticket was extremely poorly communicated. The baggage policy was not clear when I purchased my ticket, and I was charged an additional 30 Euros upon boarding to check a bag that met the carry-on size requirements (I had looked this up ahead of time), but because it was in addition to my purse (which fit under the seat), I was forced to pay to check it. Had I been aware that this ticket only permitted a purse-sized carry-on when purchasing the ticket, I would have selected a different ticket/carrier entirely. What was even more confusing was that I had flown on a similar ticket from London to Vienna, and didn't have any issue bringing a carry-on and a purse, so of course I was surprised when they told me I had to pay an additional 30Euro for the same two bags! When I tried to explain this to the agent, she argued with me and was very unhelpful. Overall, a very negative experience on Austrian Air. I will not be returning."
Pros: "Exiting the aircraft."
Cons: "United did not honour the seat assignment that Airfare.com gave me so I sat in a middle seat. But the entire seating plan on United is so bad it should be a violation of the anti torture convention."
Pros: "It was cheap and easy to book"
Cons: "Not being able to check in online, was not able to reserve seat. Even at luggage check in the flight attendants did not allow me to reserve a seat."
Pros: "Friendly crews, good coffee"
Cons: "Food is bad, and the reading light doesn't work. Limited selection of movies and tv shows"
Pros: "Great plane good price for plane ticket."
Pros: "movie selection was good. sound was surprisingly good too. crew was efficient and friendly enough."
Cons: "my seat wouldn't stay back. pretty annoying on a red eye."
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: "Comfort, timing. Customer Service!"
Cons: "Technically problems with lightning on board."
Pros: "Boarding went well. Although it was a full flight, they asked for volunteers to check in hand luggage (free of charge) I did, trying to help. But once I picked up my luggage and got to destination point, I noticed that 2 small items (gifts for family) had been pilfered. Not happy and will not volunteer to help again."
Cons: "No food on plane, no entertainment,( unless you download the app) Above pilfered items"
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"
Pros: "Excellent all round. Good price. Nice seats. Excellent staff. Good boarding and disembarking. Highly recommended."
Cons: "It does not have free food and entertainment, but for the price this is acceptable."
Pros: "Good service. And snacks served"
Pros: "Staff were helpful and smiling. Good value"
Cons: "We needed a better choice of food"
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: "Kind helpful staff"
Cons: "That you have to pay for entertainment and food on long haul flights"
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: "staff on airline great"
Cons: "Lost my luggage hopefully I’ll get that tomorrow. Airline charged me 70 pounds for that. Staff at customer service were not helpful at all."
Pros: "Great staff. Fast boarding and deplaning."
Pros: "Crew good, service good"
Cons: "Both flights delayed over 2 hours, missed connection so it took so I was in airports 13 hours instead of 6"
Pros: "Hi. I actually am glad that the company is following up because I was having a hard time finding an email to contact. I actually came to kayak to book my ticket for Friday to go to London however when I got to the airport it says it was for Monday. Because I had to be at London the next day for a wedding i had to buy another ticket for almost 1000. I also couldn’t contact u so I’m emailing now. I didn’t get on the plane for west jet because I am already in London. I also have a screen shot that shows me that my flight details were for Friday however another email shows me that it’s for Monday. Even the workers at th airport were confused and felt strongly bad for me. I would like a full refund as well. Thank you. Please contact back. 416806-6530 or email me at sarapascual@hotmail.ca"
Pros: "It was a clean plane and a pleasant enough flight."
Cons: "I was in the window seat. The guy in the middle seat spread out so much he was pushing me against the side fo the plane. Really uncomfortable."
Cons: "Our original flight was cancelled due to WestJet reasons (plane was not safe to fly) the following evening the flight was supposed to depart at 7pm we didn’t take off until 10:37 pm causing an arrival of 940AM into London instead of 7:23AM primarily because the crew they chose for this new flight was coming from Montreal so we had to wait for them to arrive."
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."
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: "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: "comfortable seats friendly crew"
Cons: "no entertainment system, fee for renting tablet not enough room in overhead no complimentary food or drink service"
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: "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: "When they fixed the aircraft it was overcrowded but okay"
Cons: "Their dishonesty. We were delayed 25hours. I am out of pocket by several hundreds of pounds. Two months later they have still not compensated me. yet the Canadians that were on the fight have been reimbursed. The message is loud and clear if you are British do not fly West Jet"
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: "The service was okay and departed on time."
Cons: "I didnt like not having entretainment (no TV or free wifi). Meals not included on economy class."
Pros: "Crew were really nice and good entertainment."
Cons: "Paying for food and alcohol was a bit of a downer."
Pros: "The crew were very friendly and the meal I pre-ordered was very nice. Snacks and beverages were complimentary."
Cons: ""Engine trouble" so off the plane and back to the gate. Not much information conveyed to us. Just sitting and waiting. Took off about 2 hours late. No entertainment. $6.99 for a tablet."

Kayak was terrible, I was told that I got 1 free checked bag, but when I got to the check-in counter I was told otherwise and had to pay for my checked bag!!!!

Pros: "Nothing"
Cons: "Kids running up and down isle stewards just walking past. Never made announcement for boarding. Worst flight ever."
Pros: "A350, smooth and quiet. Nice plane"
Cons: "Seats in business are a little crowded and close together. opening to get in and out of seat is minimal"
Pros: "Crew was pleasant."
Cons: "Very old plane with seatback screens or USB ports for charging."
Pros: "Everything! I never knew Finnair was such a great airline."
Cons: "Other than maybe the lengthy layover time, which probably can't be helped, nothing could have been better."
Pros: "Speed boarding process."
Cons: "No entertainment system on a 3 hour flight..."
Pros: "Friendly crew. On time. Clean. Comfortable."
Cons: "All was fine."
Pros: "The staff was professional and friendly. The waits were short on boarding."
Cons: "The flight was over an hour late. The baggage reclaim belt broke down, which delayed our arrival at the target even more."
Pros: "Loved it"
Cons: "N/a"
Cons: "The food was poor, uninspired, ungenerous, inadequate. Perfunctory service. Poor movie choices."
Cons: "long waiting time in the bus before the flight"
Pros: "The plane was good, the flight time was nice, just 9.5 hours."
Cons: "The boarding was kind of chaotic, but the crew was kind. The plane seemed comfortable but the seats sit too far back, so when the person in front of me sat his seat back, his head was almost in my lap. It made it hard for me to move or read or do anything. The food was super bland and the drink options were pretty limited. The entertainment selection was much more limited than most flights."
Pros: "many choices of films to watch was great too! Like that you served Finnish food!"
Pros: "My flight was very pleasant and comfortable. It was one of the few times I was actually able to fall asleep on a plane. I also like that this is the first airline that served me blueberry juice which I thought was good."
Cons: "My only dislike was that we left 45 minutes late. Maybe it was not a good situation for some passengers who had to connect immediately, but I still made it in time for my connecting flight."
Cons: "You have canceled my flight and you have just sent me an email."
Cons: "Seats were too closely spaced. Like a coffin. Will probably not fly Finnair unless the price is next to nothing."
Pros: "Arrived ahead of time Crue"
Cons: "Sales on board"
Pros: "This was a very good and on time flight from London to Helsinki. The exit row had lots of legroom."
Pros: "Nice crew"
Cons: "old plane, not clean, flight delayed not airlines fault"
Pros: "Schedule is on time."
Cons: "Food was not much excting and seat distance was rather short, making uncomfortable."
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."
Cons: "very little leg room for anyone over 6 feet"
Cons: "It was n't their fault but My wife's passport expired in 91 days from beginning travel so they wouldn't let us on the plane to Italy."
Pros: "I liked everything about my experience on four Iberia flights. The boarding was fair by groups and they didn't allow people cutting the lines. The planes were new. The food served was very good and had a great variety of tastes to please different cultures. The entertainment system on my seat was awesome!! Customizable music playlist that was All genres of music. The navigational pages were fun and interesting and the movies were current."
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.."
Pros: "The crew was very much professionals, worked fast."
Pros: "Flight left late but reached early. Plane we comfortable and had clean toilets"
Cons: "None"
Pros: "This is not my first experience with Finnair flight and I'm very pleased with a consistency of a good service, high professionalism and I will recommend this airline to all my friends."
Cons: "Seats given away that we selected six months ago even though we checked in days early. Four family members all over plane."
Pros: "Everything good except getting bag after flight."
Cons: "Took over an hour at baggage claim."
Pros: "Flight was operated by American and they really absolutely need to update their planes on the JFK-CDG route. It is the only airline that does not provide individual screens, the seats barely recline and the air quality on board on board lives a lot to be desired as the plane odor is just not good."
Pros: "customer service was attentive smart yet caring."
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: "Once we got on the flight it was all good!"
Cons: "We had the worst experience getting to our flight this airport is so badly managed it is laughable."
Pros: "Nice one"
Cons: "Nice one"
Cons: "When I arrived at CMI no ticket was issued for my second leg, so I could not use the internal transit bus to at Terminal 5 at ORD ("for ticketed passengers only). I had to exit use the external train (which was delayed) and go through the very slow Terminal 5 security. Almost missed my ORD-LHR flight (arrived at the gate after the official closing time)"
Pros: "The crew was just fantastic. ...."
Cons: "I request special meal. ..unfortunately was not provided to me."
Pros: "On time arrival."
Cons: "FinnAir Entertainment selection was not as good as British Airways."
Cons: "Finnair "outsourced" the flight to a Portuguese HiFly. Boarding: flight delayed for more than 1 hour, with passengers sitting all this time in the plane and waiting for all connection flights to arrive. As a result we arrived late for our connection flight. The Finnair people that met the passengers on exit form the plain did not provide any information how we should proceed next. We were left to figure it out by ourselves. Crew: The impression was that all the flight attendants from HiFly were untrained. The did not know what to do an how to do. They seemed lost on the plane. Comfort: Plane seemed to be re-purchased from some Arab airline. Food: bad Entertainment: v system was broken. Information system was showing wrong current time."
Pros: "Boarding was smooth and the flight crew and attendants were friendly and helpful."
Cons: "The seats were so close that we felt like cordwood stacked vertically. There wasn't elbow roon to butter my roll without elbowing the person in the next seat. The food was boring. It was very cold, despite my dressing warmly. It was a relief to board our next flight, which was JetBlue."
Pros: "On time service, very simple and fast boarding, nice crew, nobody complicated with luggage"
Cons: "Cost for additional luggage was high"
Pros: "The staff was very kind."
Cons: "If I'm paying for a trans-atlantic flight (at a fee of $1,000), I shouldn't be stuck on a plane that is used for domestic flights,and thus does not have the space nor the comfort of a larger plane. And, if this flight is not going to offer the amenities accustomed to a typical trans-atlantic flight (such as in-seat TV), then the price should be substantially cheaper. I will be complaining to the airline itself for this, and may not fly this airline again."
Pros: "Flight attendants were grumpy, food was horrible (even for airplane standards), entertainment selection subpar and boarding was confusing (i.e. they was a group "b" and a group "2"- both different? ) received no nice comforts such as eye mask, etc"
Pros: "B.787 flight operated by BA; free wine, great food and IFE."
Cons: "Seating now so cramped it's becoming dangerous."
Pros: "Nothing"
Cons: "Old plane, noscreen on seats,, can't choose movie, no charger and USB. Terrible food Very expensive for the price"
Pros: "I was running late getting through check-in because there was an abandoned backpack that caused a huge mob scene and delay. The American Airlines/(Finnair) check-in staff were WONDERFUL and made it all OK, pulling us out of the mob to get us through check-in. Then I went through security, which the check-in staff had tried to expedite, and got stopped for a random inspection. Then, after boarding passes were scanned, I was again stopped for a random search that took apart every zippered corner of my purse and my carry-on bag. But again, everyone was lovely to deal with. By the time I got on the plane I was grateful for having caught the flight, and for the kindness of the Paris staff, and marveling at what an obstacle course it had been. And I had enough leg room."
Cons: "1. The sound on my in-flight screen did not transmit the movie sounds, so I read a book all the way back. 2. The red wine was great to have. The food was like school cafeteria food, so I ate what I had brought with me. 3. The seats on airplanes never fit my body right. I sit very straight and upright, and I'm fairly tall. The airplane seats keep forcing my head forward and my back into a hunch."
Pros: "Good crew-excellent service."
Cons: "Cramped seats-I'm 6 feet tall and I need space. Emirates & Lufthansa are sooo much better!"
Pros: "Friendly staff did what they could to make you comfortable. Blueberry Juice!"
Cons: "Duty free sales trip down the aisle. No snack with drinks even during mealtime. All too typical cramped seats."
