most other airlines are very good to excellent
Verified travelerFlew with British AirwaysJan 2024
Leave plenty of time if connecting in London as most connecting flights are in a different terminal which requires a bus or tram ride. Also if you’re not at the gate 30 minutes ahead they will not let you on the plane. Apparently this is a Heathrow not airline rule.
Verified travelerFlew with British AirwaysFeb 2024
Virgin Atlantic are still the best overall for this route.

I am so shocked at the service in first class. We were not greeted or offered a beverage for 45 minutes into the flight. She did however have time to write a long note. I just wanted a snack and something to drink. We were never offered coffee and the snacks came after dinner? It was the oddest flight I have ever been on. The gentleman next to me got up and gave our dinner box’s to the flight attendant and asked for a second glass of wine for each of us. Our dinner boxes sat on our tray for 20 minutes. She was rather distracted. He then asked another flight attendant for wine… finally we had a second glass. I was trying to give her some grace, she also told the man next me we couldn’t have any more wine because we drank it all… after landing the seasoned traveler next me ask for her employee number. Then it was a mutiny! She was refusing and it got tense. The captain came and asked what was happening, the flight attendants totally gave a biased account of the fact. The captain told the police the man I was seated next to was intoxicated! That was completely inaccurate and it really escalated things. I policeman found me at the luggage carousel to verify the facts. The flight attendants made false accusations that he touched them! That never happened. It was a very poorly trained crew. I am so anngry and shock by the entire experience! It was terrible service! I would like a refund for what I paid to be in first class and the most uncomfortable flight ever. I always fly Delta, it has been wonderful. I was so flustered by the entire experience! Please give me an update on this matter! Thank you, Kelle Myers

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

Food was not the best. Too many items had sauce pm them with a lot of spices The seat was not comfortable especially when you lay down

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.

The airplanes were so old and out-dated it was terrifying to fly on them.

It’s was good. There’s so much room for improvement though. Since the plane was small, there was no entertainment but for years now, the most jarring aspect of travel is the lack of tasty snacks.

The important things including boarding and the flight being on time and safe were excellent. The disappointment comes from the comfort and amenities. Was misled by the "availability" of inflight internet- there is an extra cost. The tray table was broken, the bathroom door stuck and flight attendants were competent but not very friendly.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

The Gate Attendant @ Gate B36 was rude The flight was good but the entertainment system was not functioning as expected. The snacks were ok but could be better The flight crew was excellent.

Flight was delayed, missed connectingnflight to DC. Put me on flight to Baltimore, had to rent a car for $200. Plane was old, wall peeling around window. Flight was packed, every seat full on small plane. I spent 14 hrs on Friday in airports and missed my planned weekend event.

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 think Virgin is one of the best flying experiences, especially from/to the UK. The staff are so helpful and fun, the food is good, seats comfortable, goof entertainment and great value. Check in and boarding is pretty pain free. I also find that the other passengers are generally so kind and considerate than when I've flown other airlines.

Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

The delay was an issue. Other than that. Every thing good

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

Staff didn’t check cabin well for landing seemed more interested in chatting to each other. Food was poor and differed from pre order.

3 hour delay on run way, not even a drink offered, staff seemed rude and rushed, felt unwell so asked twice for paracetamol and was told to wait, never got it

Gate agents for boarding not trained. I am disabled have eyesight problems and was told “do it on line.”. Wheelchair unavailable in Dallas even though it was in my record

I like the speed of boarding and deplaning and the fact that everything was on time. The crew (attendants) were probably quite new and did not begin the in cabin service until 30 min before landing even though there was little to no air turbulence for the last 1.5 hours of the flight. It made for a mad scramble at the end to get trash collected and carts stowed before touch down.

not enough crew for business class and not great service as a result. underwhelmed overall

The crew was very helpful and the aircraft was clean. More attentiveness to us in business class.

Everything went on schedule so I have not much to say. I was a bit disappoint with the breakfast choice - I did not have a choice as there was only one option left by the time the trolly came to my end and I could not enjoy it.

Crew never smiled, never helped , told me to make my own bed ( in Upper class), never offered a drink

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Missed this flight due to the first AA flight delay

Missed connection from Philadelphia to London because flight from DC was seriously delayed. Was re-routed the next day (had to pay for hotel) to Zurich and was given a main cabin middle seat while I had paid for premium. Great job AA!!!

The crew on this flight was probably the worst I have ever come across. This applies particularly to Karen and Lee (possibly Jason) - the short, overweight pompous guy - arrogant and rude are possibly too kind a description. This Lee/Jason obviously failed his exams at Charm School, and frankly, in my view, needs to be dismissed immediately. Karen was similar to the guy in attitude, but not quite as rude.

Problems at check in with prepaid luggage causing delays with both flights, noticeably old and dated planes, onboard luggage bags (BA small luggage size) too big for centre overhead luggage boxes (dangerous if opened) no Wi-Fi available on outward flight, food on inbound flight atrocious, food/drink service on inbound below par.

Always an excellent experience. Staff are professional without being overly fussy.

Boarding passes should be checked upon boarding to avoid a situation we got into, delays due to wrong boarding

Horrible. Flight was canceled and customer service was way below par

The food was horrible. The crew skipped over me for drinks(only got food?). I had to wait until everyone else was served drinks in order to receive mine(meal was done). No earphones were given. No free WiFi.

The economy seats had space unlike Iberia Airlines from NY to Barcelona.

A friendlier and more helpful crew would have been much better.

WILL NEVER FLY AMERICAN AIRLINES EVER AGAIN A TRUE DISGRACE

I bought the ticket through Iberian, but I was unable to check in using my code. American wouldn’t let me check in and Iberian counter was closed.

On this flight I was in BA business class. I am used to flying United Airlines Polaris class and I was underwhelmed by BA’s business suite class. A few things: - the lounge at LAS was very basic and crowded and the LHR/T3 lounge a bit better, but still not like the Polaris lounges - boarding was chaotic, no one knew what group was supposed to board - the suites were nice, but the padding was not really made for sleeping on - crew were friendly, but only really one tray/serving for the dinner service. None of “drink first, then dinner with 1-2 pourings of wine, then dessert”. UA might not be known for the best service in the industry, but compared to BA they are super attentive. During the BA flight there was no one checking in on you after you got your one tray. - arrival at LHR was busses taking us back to the terminal, surprising for a long flight. Once again chaotic. The bus for First/Business was completely packed with anyone who could get on and the driver was screaming at passengers to get every inch packed before he drove to the terminal. By the time I arrived I felt like BA had sold me a superior flight experience and delivered a mediocre economy class experience just because they can and do not really care about their customers. Very disappointing.

Flight left late and we missed our connection in London requiring an 8 hour wait in Heathrow for the next available flight. One of flight attendants was not helpful with my husband’s necessary crutches.

Pretty good flight in general. Connection in London was extremely slow. The security was slow and understaffed. It took 35 minutes to get through and it was not even crowded.

These 777 planes really shouldn’t have 3-4-3 seats in economy. Very little leg room and the aisles were tiny. It was very uncomfortable for a 7 hour flight. (These same planes used to be 3-3-3 for seats until 2018).

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.

They canceleld the flight and i found out only hours before the flight

Flight crowded - no leg room. Made me put tote bag under seat in front of me so no room for feet. Attendant helped me and put it up. Crew fine. Also British Airways changed our flights without notifying us resulting in a lot of confusion getting through Heathrow - our boarding passes wouldn't scan and we had no idea why. Ended up missing our flight and having to reschedule hours later after a flight from San Francisco. I have the app from BA and never received any notification. Very confusing and staff at Heathrow had no idea what problem was and only one person could resolve and huge line as several canceled flights. What a pain!

One of the worse flights. Departure was delayed by an hour. Boarding was disorganized. It was freezing on the plane. The crew was not very helpful. One of the flight attendants was literally marinated in some awful perfume,. And the food was uneatable, both dinner and breakfast.

Horrible experience. They lost my luggage and still can’t find it. The plane ride was below average. Food also terrible compared to other airlines.

Wheel chair assistance was requested but found very poor status at London.
