My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Half the bathrooms assigned to economy were out of action

There was a loud squeaky sound the whole time we were flying.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith 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.

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.

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

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.

Everyone on board was great. It was just super late and we missed our connection in Frankfurt, and had to power through jet lag while we waited 4 hours in the terminal. My family missed a big welcome dinner in Berlin.

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.

United is today and old, the planes, the staff, the business processes. Yet they expect premium prices for a less than average flight experience. I should have remembered to stay away from them and will remember to stay away from them in the future since I'm traveling a lot again. In a nutshell, they suck eggs.

Two staff were rude, loud and burnt out I think. Two were friendly kind and helpful.

Frankfurt airport is the worst. Passengers are forced to use stairs to get to the terminal or catch a shuttle. Very inconvenient for passengers who are ambulatory challenged or have physical handicaps.

The entertainment wasn’t playing in the app or online.

It wasn't clear that there will be additional charge for checked in baggage. Very, very disappointed making me pay extra $75. Food was not tasty and not healthy. Lufthansa used to be good, not any more. Unfortunately has gone down big time and continues to go down.

This was not a UA flight. This was Lufthansa. Good experience overall

Food was tasteless, service pretty bad (no water offered after dinner throughout the night); seats were narrow and tight, with very little legroom.

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.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.

Overall, the flight was comfortable without any serious issues. Transit through Frankfurt airport was a little confusing, but not too difficult if you follow the signs

Staff disappeared after dinner service until breakfast, no help with beds, no help running to our gate to catch connection cause flight was late, our luggage didn’t make it, took over 24 hours to get luggage to hotel, no compensation!!

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

We got our seats and was surprised at the half empty plane, so had a very good hostess and we enjoyed the whole flight back home, so the only thing we had to wait for was the passenger assistance that was not there and had to wait about 20 mins on the jetway.

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!
