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.

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.

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

Brutal delay of 24 hours on first floight the 3 hours in Chicago . Tiny seats , screaming child behind me kicking the seat … couldn’t be worse

Horrible! I paid for a straight flight from Chicago to London. A week before trip it changed and now I had a connecting flight. Our flight was delayed an hour and a half because our flight crew was still flying in from CA. Forty passengers ran from one plane to the next. The next United Airlines flight was delayed two to three hours because of mechanical difficulties. They had to ready another plane which took time. I missed my scheduled excursion in London. 😢

Lufthansa placed a 300 lb passenger in the aisle seat and I was stuck in the middle leaning sideways with no arm rest or ability to sit up straight and fully use my seat (due to encroachment-the seats are very narrow) the entire flight.

Everything could’ve been better. The boarding process was a little tedious, and then they put me in a seat with the window did not open, which gave me a very uncomfortable feeling considering I had told them that. The entertainment system didn’t work for quite some time and because I had to heavily medicate myself to not have a panic attack I missed dinner and barely ate anything on the flight. Not to mention the religious man next to me, praying mostly and humming the whole flight.

It got us to our destinations pretty well but the flight from Dulles to Newark was the size of a school bus or less and the flight to Israel was better but premium seats are way tooo expensive and necessary. The seat cushions in economy plus are virtually nonexistent. The service was minimal. There was a noticeable absence of beverage service, including nonalcoholic beverages. The flight to Israel was my mos on time flight to Israel ever. The pilot talked too much, though, especially yelling instructions at everyone.

UK Based crew was great. Very friendly and quick. The seats are just too tight and not comfortable. The plane appeared quite old. Food is better on other non-USA based airlines.

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

delayed multiple times. no resolution on anything from AA customer service. was put on hold in chat to talk to manager. was 6th in line to talk to manager for more than TWELVE HOURS - from sometime around 9AM until well after I had gone to bed that evening. no explanation, no attempt to make it right. just a five hour delay because of repeated maintenance claims

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.

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!!!

Original flight delayed several times and finally canceled at 2:30 in the morning. Staff at the gate was not very helpful in resolving problems or communicating why there were delays. I spent 34 hours at the airport before I could leave, they couldn't book me on another early flight even after canceling my original flight. Next flight available after my original flight was canceled was 22 hours later. I will never fly American Airlines again.

very very tight seats unfriendly crew who do not seem to care about the comfort of their passengers and do not know how to smile poor ground staff support at LHR and PHX

So uncomfortable to sit in the tiny space on a long, international. Food was rough. Please, less white flour and processed food.

Very bad flights I lost my luggage for both sides

This time it was not good. The plane was not clean. It had a bad smell as if the cabin was not cleaned properly. The small sit pillows were dirty and blankets (even though they were packaged) did mot smell clean. Decaf coffee was disgusting and tasted like instant coffee.

Staff was helpful. we left on time and arrived early to destination.

It was disappointing that I could not sit next to my wife but I was not allowed to pick my seat

Missed our flight to London and we were put on coach seats to Munich.

Seats were terribly uncomfortable! Couldn’t sleep! I paid for good seats when scheduled with Lufthansa, got crappy mid-section seats on Air Canada!

No refreshments apart from a bottle of water. No pillows. No entertainment. Flight delayed by 52 minutes.

The seats are much too narrow and the arm rests are hard and awkwardly high, resulting in shoulder cramps. I am an average sized person ( definitely not overweight). The seats are a similar size to car seats with the added discomfort of incorporating hard plastic arm rests, that force average height individuals (I'm 5 ft 7 (f)) to hold their arms uncomfortably for several hours. The seats are much too close to the ones in front and behind making it extremely difficult to allow fellow passengers to get out, especially when the seat in front is declined. The leg room also necessitates knees banging into passengers backs for the entire flight. This used to be a quality airline who now offer mediocre service for premium cost, coupled with charging exorbitant prices for basic needs, like a seat, or luggage. Blatant and unabashed gouging of clients.

There was a screaming child behind our seats. This prevented us from getting any sleep during the night.

Not your fault…..didn’t get my drink until just before landing….bumpy flight.

It took an hour and a half for luggage to be dlivered in London

We were seated in the rear of the plane. Buses arrived to take us to the terminal but there weren’t enough so we waited an hour to leave the plane.

Chicago to London flight was delayed an hour . Boarding process was slow . I missed my connection to New Delhi and My connection from New Delhi to Ranchi. Now come the really outrageous part! There was a flight from London to Bangalore that would have allowed me to reach Ranchi on time. I was about to but ticket from Bangalore to Ranchi when BA agent came back after talking to someone in back office and informed me that she cannot rebook me to London Bangalore flight as Bangalore was TOO FAR fro. Delhi. I waited 8 hr in London airport. I was flying business. Hope this review helps the airline. I was not asking for any money back for my missed flight. Anand Mohan

The only issue I had with the flight is that dinner took a long time to come even regardless of the turbulence we experienced. The flight attendants kept disappearing while serving people and kept some people waiting. Which caused them to forget to serve me some tea. It was resolved eventually. Just a small complaint. Maybe there's other reasons but overall the flight wasn't bad.

The check in lady was the best I have seen at JFK she was very nice

The perfect jet stream back saved over 1 hour in the air.

They cancelled the flight from Dallas to London and rebooked following day causing a lot of pain

Baggage handling was very poor, I didn't get my luggage for 4 day's on way back. Neither a responsible person to answer my call. Kindly see my call log on lost luggage reference no BOMBA41916. all details are recorded. Difficult to convince me to fly once again. Sorry for harsh words.

Every flight was late in arrival, last was late in departure and late in arrival, then lost our luggage!

The flight, food and entertainment we all decent, except for a mishap when an attendant accidentally dropped a hot breakfast plate on my son who was fast asleep two hours before landing in London. She was very apologetic, and offered to help pay for any dry cleaning, but we have not received anything from BA. What could have been better, however, was the lack of any support upon landing to make a connection. The original flight from LAX to London had been delayed, so our time between flights had been cut to only an hour. There was no staff helping direct us where to go to get through security. When we approached anyone to ask for help, they acted bothered. I was traveling with four children that needed to use the restroom and get cleaned up after the spill, so we had to stop briefly for that, but again the gate notices directing us where to go only said to get to concourse A, there was no gate assignment. It was a busy time at security, and the process was slow, but we still arrived at the gate 10 minutes before the scheduled departure only to be told the gate had closed. We came to find out that our connection to Paris had actually taken off 5 minutes early, but without us, and six of its passengers. British Airways had to be aware of our delay and known that we had made it to security, but did not make any effort to ensure their passengers could make a tight connection through a crowded airport. Rebooking a flight for 8 hours later was not a pleasant experience and when we finally arrived in Paris at 1:00am, we arrived with only two of our six bags. Again the original flight was okay, but the support on the ground was greatly lacking.
