The food was delicious. There has been a major improvement here in the last few years. Excellent, friendly service. An enjoyable experience.

Awful. Delayed for unknown reason. Boarded late, part of a Tight connection ands had to go through customs and immigration. And they lost my bags.

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

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.

This has been the worst experiencia I have had traveling overall. More than 3 delays, no one answering questions, no one at the AA counter. No one at customer service and after having to change transportation to airport and spend the night at a hotel paid by me, we were delayed inside of aircraft for more than 2 hours!!! Bad experience!!!

Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

The flight was surprisingly good, especially given initial experience. BA app is horrible as is their customer service. Online check in was a horrendous experience and when I phoned their customer service number, the live agent with whom I spoke was rude and dismissive. She did helpfully inform me that their IT people were working on a known problem related to online checkin. However, once she delivered that information, she curtly ended the call before I could suggest that since BA was aware of this, it should be posted on the app and online. I grudgingly flew BA this time - have avoided them for years because of past similar serial bad experiences. While this flight was fine, I’ll return to avoiding them in the future given the hassle experienced and rude personnel.

Boarding was a shambles, with no proper line or queue and multiple groups joining at the same time. Overhead space was limited. Seat spacing (width) is not generous. My neighbour was invading my space, before he even spilt his drinks over me (twice!) as he struggled to contain his meal on the table. The main meal was very poor. Choice was simply chicken / turkey - the crew didn't know exactly which - or vegetarian. The chicken meal was really poor quality - uninspiring and tasteless; and very little offering of drinks. Half the crew were friendly, half really need to cheer up.

LHR is always kind of a challenge. British Airlines did a fine job. My tickets were the cheapest so I can’t complain.

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

My screen didn't work for the first 9.5 hours of the flight. The crew could not resolve. I don't watch much media so I had been really excited to relax and watch a BBC special but couldn't. Then I tried to use the online streaming on my devices - that never worked but I do have about 7 charges on my credit card that I now have to dispute with BA. Pretty annoying. Also, they ran out of meals and they served meals that had a serve by date of 1/26. But the staff were all very friendly and helpful when they could help.

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

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

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst
