Late, dirty cabin, charging ports broken, uncomfortable, no tomato juice, barely edible food

Finnair was not able to get our luggage on a connecting flight and there was a substantial delay of two days to obtain our lugguage. They did not communicate well, and we had to travel a significant distance to finally get our luggage. It has been a very negative experience.

Flight on time, landed well ahead of schedule. Attendants were excellent and responsive

The crew was friendly, and the flight landed on time

Rude Iberia security crew at the Madrid terminal. No Iberia officials to be found to redress complaints at the gate. No supervisors. Nothing for processing upgrades at the gate Iberia app did not work to let me upgrade my options to higher classes. No water was offered on a hot day in Madrid. Madrid airport air conditioning was so weak that people were sweating. Never book on any airlines that codeshare with Iberia.

Great if not for the boarding by bus at Heathrow terminal 3. Medieval disappointing time-consuming and very hard on handicapped flyers. It was awful

Positive: It was refreshingly easy and polite check-in and boarding staff. Flight was on time and Helsinki is a very well-signposted airport. Shopping was nice as well. Flight was not full and I had lots of space in economy. Flight was perfectly on time. Negative: Food and drink not very good, but that it is normal on any airline. Didn't expect anything else.

Business seating is soooo uncomfortable. You can sit straight up or lay down. You need pillows behind you because the back doesn’t lay down. Those are need to “prop” you up. The chair has no padding whatsoever. Food was gross. I’ve eaten on Finnair before and the food was exceptional. This time it gave 2 people in our party diarrhea. It was the chicken dish. I took 2 bites and didn’t eat anything more. The flight attendants were nice. You needed an additional lounge in Terminal D at DFW Airport. After waiting 40 minutes to enter, we finally gave up and went to a bar across from the club doors. I’m unsure if I’ll ever book a Finnair flight again.

Very good seat, very comfortable, good food, and good service.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

Seating and zone. The minor I went with didn’t even seat close to me

My seat 3G did not go down fully and the buttons were not working properly

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

Crew was nice, aircraft dated, entertainment same. Internet is expensive and terribly slow. Food pretty bad

Horrible experience. Food was ridiculous, insufficient, and not appetizing at all. They served sugary granola bar for breakfast. Furthermore, my bags were delayed and delivered damaged and American made it impossible to file for damages. Furthermore, the flights were delayed causing unnecessary stress given the connecting flights. It was awful experience, would never want to fly American.

My table was broken so it made it difficult to eat the food during the service. I was also informed that my luggage did not make it with me to Phoenix. I live two hours away so this makes it even more stressful to try and arrange a time for pick up

Part of my stress and frustration was 50% with the TSA security. However. It is nearly impossible, if you are flying long-range and carrying luggage, to get through security and to the Gate before it closes. I was scheduled to fly out at approximately 12 and got hung up at TSA from 11:00-11:20. When I looked at the screen, the gate was already closing. I have to run to gate 24. Barely made it - all that to say you might consider lengthening the connection time by at least 30 mins.

Very hard to beat a British Airways international flight…the crews are always so amazing! One flight attendant that really stood out was Emma…she was very personable and accommodating with any request we had!!

The passport line was so long that many of us were concerned about missing our flight and some did. It would've helped if a AA representative had gone to the passport check-in sooner to advise that boarding was closing and those flying that were stuck back in the line, needed to come forward with apologies to others. An AA representative did do that but only after boarding had already closed. (They delayed take-off so that more who were running with carry-ons could get to the gate - especially stressful for older people!) Then to be crammed into a seat with barely enough leg room for a thin woman, 5'7", like me, much less for a taller, bigger person was not comfortable, especially if the person in front decided to lean back. Crew was fine, food and entertainment also.

The seat when "flat" was not flat and pad was too thin to cover it.

Awful customer service, horrible experience. We travel a lot domestic & international- worst flights to/from ever. Brief bkgd as Inhate to relive this experience: booked and chose 2 seats 4 months prior in Premium Economy - last row end seats close to bathroom, no one behind us, plenty of legroom;, underwear storage — flown this was on other airlines, love it. We receive notice 4 days before scheduled overseas flight - plane has changed, new seats assigned. Seats are split into single seats, opposites of the plane, FRONT Row so no reachable storage. Called BOTH British Air & America. American “switched planes and the seats you want are taken;” British Air “Yes, we’ll be glad to accommodate you (type type type). Just ask at the Gate and someone will give you new boarding passes with seats together in middle, OK?” — OK. —At Gate the attendant looks us up saying “No, it is an overbooked flight and yours are the only seats available.” But but but wait, “We were TOLD our seats had been switched and seated together?” Gate attendant “Well they were wrong and don’t change your seats. Your original seats are where you’ll sit.”. Right. No help WHATSOEVER. We sit opposite on way there, wife VERY disgruntled, a Tol 5 worst ways to start a 3-week bus tour of UK. We promise to NEVER FLY AMERICAN OR BROTISH AIR EVER, and we have 3 more extensive trips planned..

They lost my bag. ... And I asked them 3 times to 3 different people if my checked bag will maKe it all the way - they all confirmed and at the end it was left at the connection... Bravo

British Airways is an excellent airline. Comfort, food and airline personnel.

Crew at gate and onboard were just very OK, not very friendly and honestly seemed bothered to be there. I will give a shout out to still selling headphones for those who forgot.

We travelled from London to Halifax. Customer service was excellent.fron the day we booked until arriving. The gate was only a short frombthe waiting area and walk Boarding was efficiently handled and plane took off on time. The service on the plane was very good. Fool an acceptable drandard Only downside was that the legroom was tight for anybody just over 6ft tall and am usually able to travel without difficulty. I will definitely fly with Air Canada again but next time pay for extr space.

Was disappointed when landing in Canada was made to wait for over 1 hour with several other parents and babies for our strollers . The expectation was that the gate checked strollers would be there when exiting aircraft. This was not the case we were told to walk to a point and wait for them . After being left there and not being updated we were met with very hostile and rude air canada staff . There where no apologies or understanding even though all the children where very uncomfortable and the parents very frustrated as you can imagine . Instead the air canada staff at the airport where very rude and made an already frustrating situation much worse instead of trying to assure the parents that that were making effort to fix the situation. One gentleman in particular was very rude to some parents telling them to move when they were simply seeking information. He made the other parents including myself feel very uncomfortable. He also told a gentleman he was capturing images of everyones boarding pass when this was untrue as he was only taking a photo of the gentleman pass which was strange.

Our original flight was cancelled due to mechanical reasons. This cancellation caused us to miss our connection and we were not able to get another flight for 3 days and then needed to make an extra connection to get there. Air Canada did not rebook our flight for us, it took several hours of talking with staff in the airport and making phone calls to get the flights rebooked. We never received a voucher for our hotel and meals while we were waiting for our next flight and it was only after talking to several staff that we were provided some general information about how we could be reimbursed. We tried entering our ticket information in the website provided, but it did not recognize our flight information. When we asked someone on the phone about this they said we'd need to contact the customer relations department, but that it's not possible to reach them on the phone. I don't understand what company would have a customer relations department that you can't talk to. We spent about $1,000 for hotels and meals for our family while waiting for a flight home and I'm not confident we will ever get reimbursed for this. I understand that mechanical issues can happen to any airline, but this is the 4th time that this has happened to my wife and I on Air Canada and we have only flown Air Canada about 8 times, so this is not a good track record. Also, when we did finally get a flight home (which was also delayed due to mechanical problems), we were told we couldn't bring a standard carry on even though the information on our ticket clearly indicated that we could bring a carry on bag. The staff at the gate were not understanding about this situation.

It was good, seating was a little tight apart from that all was well.

I liked the flight but the check in was horrendous. I have booked with you before but not ever had to pay extra for luggage, it was not clear on booking, I didn't know there was different categories of economy that meant different allowances. So was alarmed when we had to pay a further £120 at the check-in at a point of not changing.

I wish they gave the earphones earlier rather than when we are already in flight.

Very nice staff members are very nice and friendly helpful

We were a little late pushing back ,but arrived a head of time.

W ended up getting stuck in Edinburgh Scotland during the air strike. They cancelled our flight and No help to get us rebooked. All said down that cost us over $2,000 extra at least to get home. Hopefully we will be reimbursed somehow! Won’t be flying Air Canada again

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

The plane was a long way from departure lounge. The plane looked tired but got us there.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.
