A smooth flight; a little cold on the ground and then suddenly heated when in the air; legroom on the 737-800 worse than on the outgoing flight, on 737-900. Much prefer flying Alaska to the northwest than flying American anywhere!

A smooth flight; a little cold on the ground and then suddenly heated when in the air; legroom on the 737-800 worse than on the outgoing flight, on 737-900. Much prefer flying Alaska to the northwest than flying American anywhere!

The flight was canceled and dumped everyone in Albany. I still haven’t received reimbursement for transportation for getting to NYC or appropriate compensation for the cancelled flight.

My experience was significantly impacted by problems in Seattle with luggage check-in. Apparently, Alaska Air was significantly understaffed in this area for the number of passengers for that morning or they had issues with the machinery processing and loading the baggage. Upon tagging my suitcase, I was sent from one drop-off area to another and yet a third on a different floor. The line to do most of this was VERY long and moved quite slowly at first--I just barely made it on time to catch my flight even. though I arrived at the airport an hour and 40 minutes early. Then when I arrived in Charleston, my bag didn't arrive on the carousel with other luggage and I had to spend extra time tracking it down.. The relative who helped me out at SEATAC said he had never seen the airport so backed up and he travels out of that airport frequently. It was a very stressful experience, and very disappointing.

NO ENTERTAINMENT OR WIFI OR FOOD. ONLY WATER TO DRINK AND SPICY PRESTLES TO TAL CHAEOS AT CHECKIN

Boarding was smooth, the crew was kind and friendly, and even though we were in the Saver class, the seats were generous enough for my daughter to nap on me and I had enough room to recline and sleep for our overnight flight. If I had stayed awake I might have quibbled with the lack of a true meal, but the snacks worked for me and when my daughter was hungry (as she did NOT sleep), the crew took care of her. There was room for all of our bags on a very full flight, which was nice. It has been awhile since I haven’t checked a bag, so I had worried.

Customer service of one flight attendant, impersonal to asking questions

Great and comfortable aircraft. Good food and the staff was amazing

Someone rebooked my Alaska flight to a much later Delta flight. Now I am sitting at the Seattle airport after a long international flight and have to wait another 4 hours even though I would have been able to catch my initial flight

Terrible. Flight delayed 7 times. Lost a day of our vacation, loads of money and non-refundable activities. Can’t fly AA again.

Everything was good except for the child that cried most of the time/

The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

Passengers need to check in big baggage instead of bringing on the plane. That cause inconvenience for everyone. Otherwise flight was good.

Great. Very smooth. Plenty of information. However, wish they would give out a menu in advance of making a dinner choice like other international airlines. The flight attendant says chicken or pasta and there are details about ingredients or spices requiring the passenger to ask which requires the flight attendant to answer many times. So easy to solve this problem. P

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

Late flight caused a missed connection, had to be put on a later international flight without my requested vegan meal.

Half the bathrooms assigned to economy were out of action

The crew members were great. The food was good. Entertainment was average - Could use a wider and better selections of movies and series.

Flight was cancelled after 3 1/2 hours. Support for rebooking was overwhelmed. Lost first class tickets and to fly economy.

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

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

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.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

The crew was very good. However, the equipment was a bit dated. Some of the electronics were not working. To top it, three bags didn’t arrive with me. Two of them were delivered a day later. I’m still waiting for the third bag, I was so looking forward to this virgin Atlantic flight, but, I am disappointed.

My only complaint is that the pocket in front of me was ripped and my things, like iPad and airline magazines, kept slipping to the floor.

Flight delayed yet again. Crew apathetic and unhelpful re affect on connecting flight.

i saved my points for more than 10 years in anticipation of treating myself to an upper class fight to and from london on virgin atlantic. i was shocked to find what you consider “upper class” on the dreamliner. it was, at best, a mediocre business class accommodation. it was tight and not that comfortable, with nearly no personal storage. everything was cramped and just generally disappointing. once i lucked into a 1st class upgrade to europe on lufthansa - a magical experience that found me reluctant to sleep, lest i deprive myself the joy of their setup. i expected something similar from virgin atlantic, but i could not have been more wrong. it will be the same arrangement on my flight home, but at least i know what (not) to expect. to be clear, this is only in reaction to the physical accommodations. your people were, and always are fantastic.

Damage May baggage and I report the airport agant and they see it

Crew was very friendly. Need lay flat beds! More snacks

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

Screen didn't work, and neither did the button to tilt the seat even though the seat was comfortable

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

7 hours 15 min flight from SEA to Iceland with no inflight entertainment and no power to charge your own devices, also no meal service, not even any snacks/cookies. You have to buy food and the options are extremely limited (i.e. ham and cheese sandwich and spicy cup noodles). I didn't think Iceland air was a budget airline, maybe I was wrong, the cost of the ticket didn't feel like it though.

Very nice flight, easy connections in Keflavík, and friendly crew.

Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Moved me away from my family and refused to fix it.

Connection at Hethrow was horrible..We couldn't get out of the plane for an hour as they were buying people to the airport and there were not enough busses. We had 2 and half hf between flights so it was very tight. After departing plane we had to go thru security again. People with less time in between connections missed their flights

Captain sick. Unable to get replacement so delayed me 30 hours, many others delayed 54 hours. TOTALLY DESTROYED ALL MY PLANS, including lost my rental car which would now cost over 5 times what I paid so stuck with buses n trains... lost hotel reservations.... HORRIBLE!!!

The BA business class cabin is excellent,very comfortable for sleeping but the service could be improved.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Could have done with a 2nd round of drinks even if it was only to distribute bottled water

The second leg of my flight unexpectedly got canceled. I was stuck at the airport for the whole day and instead of flying out that morning I flew out in the evening. For some of my fellow passengers it was the second cancellation and their original flight was supposed to go out the day before. There was no reason given though getting rebooked was quick even though I would have preferred if I would have been on one of the earlier flights that day. Compensation was a £10 voucher for some food at the airport. I eventually arrived without further incident but but due to the cancellation, it was one of my more frustrating travels of my life.

Due to a cyber attack at the SeaTac airport ALL of the airport computers at the airport were down. This seriously impacted every airline at the airport and the resulted in our flight leaving a hour later than scheduled. This delay caused us to miss our connecting flight from Heathrow to Edinburgh. I was amazed to have British Airways staff meet us at the gate as we left our flight. They quickly provided us with new boarding passes for a flight going to Edinburgh later the same day. Problems sometimes happen but they handled the situation in first class style.
