Wonderful crew, great movie selection and good food. I prefer Airbus to Boeing, much more comfortable

I wish the inflight entertainment system options were broader, but overall this was a fantastic crew and I can’t express how cheerful, welcoming, and attentive they were.

Flight was operated by Virgin Atlantic and it was up to their usual high standard. Minor grips about some issues, but they are really first world issues and as a whole, was an excellent flight.

I paid for a business class ticket on Delta. It was sourced to Virgin Atlantic. They changed out the aircraft which had fewer upper class tickets. Even though I'd checked into the lounge, was receiving alerts via kayak about the delay and changes; no one informed me that the seat would be changed - until I attempted to board and was told that I would have an economy seat or they could search to put me on another airline. Even the flight crew were informed of this change (10 passengers were bumped out of Upper Class) around 2 pm (1400) time. Hours would have helped to consider alternatives instead of making a last minute change. There needs to be compensation from both Delta and Virgin given this change in service/experience.

Movie selection was meh. Food was great. Crew as always great. I paid for premium because that’s the only way not to feel like a sardine. That’s how economy should be imo. Sadly passengers have to pay an extra $1000 to get what they should at base price but that’s all airlines. The airline industry in general treats passengers as cargo.

Wrong numbers on the seats, side rows had different numbers than middle row caused lot of confusion.

Ongoing flight was delayed. Staff at bag recheck was able to get us on an earlier flight. With only 20 minutes till take off we feared our bags would not make the new earlier flight. We were most delighted that they did and were there when we landed. Delta came through

When checking our bags at the Virgin Atlantic counter, the employee told us that we should go to Delta because we needed to verify our passports and our names. Fortunately the employee organizing the line stopped us and asked why we didn't hand over our suitcases. He sent us to another line and told the employee that we already have the passports verified in the reservation. She understood and received our suitcases. In London they have a general waiting room, where you stay until the gate number of your flight is announced. KAYAK informed us the gate number hours before the airlines did. Just like the flight to London, the legroom is too small. abusive for a flight of so many hours.

Bathroom broke, had to rush to board because of late exit of previous flight

Flight delayed for people who “should’nt have gotten thru tsa” had to look for their bags took two hours With no explanation had never happened Poorly handled
