Airline reviews

The wine was low quality Finnair label stuff in small bottles and only one small bottle each. Embarassinng. A competing airline served me two generous glasses of a nice South African Shiraz from regular wine bottles, a Beck's beer, and a generous Dewar's White Label on the rocks. Cabin service was good and polite, plane interior was beautiful, but cramped.

All good- I love BA and the professionalism of the crew and pilots.

Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

Sorting on line would have been appreciated Onward information on flights missed No ability to get seating arranged before we got to gate Very unfriendly at gate

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

I booked the flight with Finnair, which made the arrangements for downloading a boarding pass unnecessarily complicated. I wouldn't do that again. Instead I'd book direct with AA.

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

Had a nice flight to London on BA will fly with them again in the future

Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

I was pleasantly surprised. I booked the "club class" which was basically like Domestic First Class. The service was superior. Food was pretty good. Seats and cabin were comfortable. For the price I paid, I was very pleased.

Super unproffesional flight . Flight attendants were unproffesional. I could hear them gossiping about theor boyfriends the whole trip

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

The ticket price was reasonable, food was okay, not the best. I would use the service again.

Actually the flight was on time. New plane, food was okay but not great.

Old plane, hard seats, 1.30 hours delay, while seating on the plane waiting for departure.

Great boarding. Everything was on time. Plane was a bit old and the crew could have provided better drink service.

Crew was pleasant. Aircraft was very dated and uncomfortable for our nearly 4 hour flight. We were in row 17 and they ran out of purchasable food by the time they got to us.

We were lucky enough to arrive at the right time. The staff at YYZ did our complete check in and luggage tags for us. Even made sure we knew where we were to head next and how to get there. It truly was one of the best and easiest check inside. Thanks team.

Compagnie efficace et bons prix. Les sièges en classe club pourraient être plus confortables.

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Horrific, we bought our tickets 6 months in advance and paid extra for specific seats close to the front. There was an equipment change to a larger plane ( more seats), identical configuration, you would believe they could honor the seats we purchased. Unfortunately not, and they sent multiple alerts from 11pm to 2am, keeping us up all night. Eventually my husband was moved to the back of the plane with 40 rows, 10seats wide, 🟰 400 people ahead of him to deplane. ( we had a time constraint we had to catch on landing) I don’t mind a middle seat if it is my husband or travel partner, but if I thought there would ever be a chance we would be separated. I would choose an isle. There was no one we could contact as we were at sea, with no cell service. Once docked, We went to the airport an extra hour early, no help at all Air Canada check in counter told us we don’t work for air Canada, call Toronto. Horrible service all around. When you pay for seat selection, don’t count on it with Air Canada. ☹️

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

Didn't like that we couldn't be seated together or seated away from the stinking toilets or check in on line. All rather poor.

Flight attendants were great. The food I ordered was actually pretty good, and I appreciate the non-tuna snack. That long of a flight in those chairs is just brutal.

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

They changed my flight twice. The 2nd time they changed it they did so the day before the scheduled departure and replaced the lie flat seat in a 777 to a 737. I paid extra to be in the 777 only for them to change it. Then the departure was delayed twice. The connecting flight was also delayed.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Flight was on time early arrival better entertainment good staff.everything was excellent

I don’t think there was entertainment? No mention of it. It was a good flight. Only complaint was my seat cushion was not attached and kept slipping.

Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.

boarding needs to be streamlined load the back of the plane first

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

Overall great flight experience- on time, lots of food and movies.

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

We were helped whenever needed and had a pleasant flight.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.

Really quick check in and security at Heathrow Terminal 5. Staff on board were lovely and very friendly. Could have provided a few more drinks on the flight but they were available at the back of the plane.

Flight boarded and took off late for unknown reasons. Crew insisted we check our hand luggage due to full flight, which it was not even close to full. Then had to wait almost an hour a and a half for the hand luggage to come onto the luggage belt since it was loaded last. This came after many hours of traveling pregnant with my 6 year old daughter. Really didn’t appreciate the unnecessary delays. What the hell?

Left late. Crowded like cattle. Standing and waiting. Food on board getting worse.

Terrible- the flight time was delayed and then I was denied boarding because I arrived at the new time of departure

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

Our flight was delayed by over 6 hours. We then had to deplane, stay overnight in a hotel then fly out the next day, 23 hours late.

I would have preferred something lighter for the second meal. Maybe a small sandwich .
