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

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

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

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

accomodating check in staff, friendly flight crew ( a crew member was speaking tactlessly and was overfamiliar with passengers

Seats need to be updated. Allowance needs to be made for dinner service at an alternative time

If I could fly Virgin Atlantic airlines to every place, I need to go, I would. Leaving Heathrow through the special virgin air entrance, security is completely white glove service. I love this airline. From ticketing agents to flight staff everyone tries to make it a wonderful & happy flight experience. I wish other airlines copied the positive culture of Virgin Airlines.

Premium was very comfortable. Food was delicious. I had specific diet requirement and Virgin Atlantic ensured it was provided. Onboard crew was very friendly and caring. Extremely smooth journey. I wonder how upper class experience would be. Perhaps one day, I will try upper class.

On arrival to JFK it to 3.5hrs to clear immigration, as only 3 booths open. Almost missed connection

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

Have travelled business class with other airlines who profess to be the best in the world. They can however not beat the service and comfort that BA provide.

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

Why does a reputable airline like BA allow a miserable domestic airline like AA to operate its flights? There is no comparison between the two

Delayed flight due to lack of crew caused me to miss my connection

Lost my luggage in London Was double charged for luggage

The plane was clean. The crew were lovely. Food was good - but seat 1D is a poor location. - the crews cupboard is right near your feet and they visited them frequently swishing the curtain from the galley onto my feet everytime also creating a swish of cold air each time & then slamming the door.

Horrible. I bought a flight with British airlines from Amsterdam to Orlando via London. Less than a day they changed my flight to London so I had to fly to London city airport and then find my way to Gatwick for my connecting flight. It was very costly
