Heathrow is too gigantic to have less than 2 hours of layover time.

My trip was delayed by more than two hours and missed my connecting flight to Fiji due to delayed they have to change my flight to United Airlines and stranded in San Francisco for 24 hours waiting for United next flight after almost 3 days I finally arrived in Brisbane airport but my luggage wasn’t here and now I still don’t have my luggage and still without my clothes and my needs. The first full day of my vacation is horrible because I don’t have any clothes and still trying to contact airline for luggage update and hopefully they will tell me the truth instead of misleading me and I end up waiting around without enjoying my vacation time here in Brisbane.

My trip was delayed by more than two hours and missed my connecting flight to Fiji due to delayed they have to change my flight to United Airlines and stranded in San Francisco for 24 hours waiting for United next flight after almost 3 days I finally arrived in Brisbane airport but my luggage wasn’t here and now I still don’t have my luggage and still without my clothes and my needs. The first full day of my vacation is horrible because I don’t have any clothes and still trying to contact airline for luggage update and hopefully they will tell me the truth instead of misleading me and I end up waiting around without enjoying my vacation time here in Brisbane.

I was offered a selection of drinks and given a free snack. The flight was only a couple of hours, but we were trreated better than the transatlantic flight.

I was much more comfortable on this flight since it was not completely full. Again the complimentary food was inadequate for such a long flight. A tiny bag of mustard flavored pretzels and small drink . I'm glad I brought a few granola bars with me this time.

Plane was clean and modern and spacious, usb ports all worked. No TVs

Baggage pickup in Seattle took over an hour. We were told one, then moved to another, and then back to the original. What should have taken 15 minutes took over an hour. When waiting to board our flight in Seattle to return to DC, we were sent to 4 different gates before finding the right gate. I have walked every inch of Sea-Tac Airport. The actual flights were great. The rest, not so good. "Ain't no way to run a railroad."

Room is great! Excellent value. Boarding & service extremely good. Food was the worst I’ve ever had on a plane.

Multi gate changes and flight delay were irritating. Food on board was terrible and expensive for what was offered.

Overall the experience was good. Check in at the bag drop was challenging as the system was having issues and there was only one attendant helping the passengers. My personal experience was okay as it was straight forward but there were many who were having issues. The flight was good. I did not use the in flight entertainment very much as I had brought my own but it seemed to work well.

Technically this was the flight where they lost my bags, but I already explained that on the review for my connecting flight, so I'm not gonna do it again.

Hate the way they nickel and dime you on pricing. Extra for baggage, extra for a pre assigned seat. Make it one price and be done with it.

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

The flight was excellent, the crew was super friendly. The only complaint I have is, 3 of my zipper handles were broken and there were 2 massive scratches on the back of my bag

Had to cancel and rebook, KLM connection was cancelled prior to departure, ended up flying to Munich on non-Delta carrier.

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Empty seats next to me - wish it had been for a longer flight!!

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

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.

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.
