United really looked after me, just make sure you arrive good and early to ensure an unpressurised check in
Verified travelerFlew with British Airways-May 2025
Heathrow has good signage. There are lots of people going to the same terminal waiting for the train. Be patient and when you have connecting flights choose a 2-hour layover.
JamesFlew with American Airlines-Apr 2025
Try to avoid Heathrow! Not the most convenient to get into London unless you have a driver. Also, Heathrow needs better signs on where to go to exit and better wifi for foreign travelers.

Food was okay. Seats were a bit cramped. In flight entertainment headphone socket didn't work on my seat. Wifi was great, so I was able to stream on my iPad

Food was okay. Seats were a bit cramped. In flight entertainment headphone socket didn't work on my seat. Wifi was great, so I was able to stream on my iPad

Selection of movies didn't include recent box office hits. Food was average not great. English sparkling wine is not drinkable. Otherwise, everything was great.

Check in at the desk was very slow pus Security, although not Virgin issue at JFK was a nightmare. 50 minuet wait no time to explore airport and get last minuet gifts. total wait 1.5hours

Great staff great experience, made a 2 hour delay very bearable

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

It was great. I really love the app. User friendly and very comprehensive when it comes to having information at my fingertips tips related my travel.

Seat would not recline, and charger did not work. Person in front of me reclined before we took off and left it reclined when they got off the plane. Nobody ever told them to put their seat in upright position....which meant I was somewhat trapped in my window seat when deplaning. Another passenger had to go to their seat and un-recline so I could get out.

- delayed because video screens not working - delayed getting a gate at DCA Just continued bad experience IAH to DCA.

I couldn’t give an honest evaluation, because the Houston airport has a problem and I was stand up for several hours and after a long trip from Munich I feel really very tired

The experience was good overall; however, my United Airlines Mileage Plus Account didn't reflect my flights to Houston from Newark. In essence, my mileage rewards points do not reflect my actual travel. This should be corrected.

Good flight, even though there was a delay, still got back on time

First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.

Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

The Polaris experience is top notch. From departure lounge to arrival lounge. Everything was top notch. One of the best first class experience

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average,

I tried to check in beforehand from Ireland. The Jet Blue website sent me to the Aer Lingus website and vice versa. I tried to get a boarding pass at Dublin Airport as well, but they said they couldn't help me either. I had to wait until I arrived at the gate in Boston to secure a boarding pass...it was a bit nerve wracking.

Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

I was asked to pony up an additional $239 (over the $735 paid originally) for a one way middle seat, which was very uncomfortable. Where did you expect me to sit?

Jet Blue sevice was good. Just don't understand why they charge for earphones to listen to flight entertainment. Other than that, everything was excellent.

Mostly good, flight take off in time and land earlier I can’t ask for more..

The flight left unexpectedly early. Although I checked in at the gate, the crew made no attempt to contact me to inform me that what had been a delayed flight was now departing before the scheduled departure time. No announcement on the PA, no phone call. When I checked back at the gate for the delay status just before the scheduled departure time, I was told the doors were already locked and the flight had left.

The wifi didn't work and I needed to do some work. This was a business trip.

The food took two hours to be delivered to my seat, when I'm on an overnight flight I want to sleep asap after take off

Jet blue just had great service overall! Only a little turbulence heading out of Austin, otherwise the jet stream helped the speed of the trip!

Flight was fine, price was good but food onboard was abysmal. I was on there for breakfast and lunch and dinner 845am EST to 845pm GMT and all I got was a yoghurt parfait, fruit and a piece of cake. Later snacks included an ice-cream brownie and a pizza twist. I was hungry by the time I landed and the airport amenities were closed. Not happy.

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.

Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

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.

The team/crew were excellent. The USB ports were not working/broken, I tried multiple ports and also asked a staff member to check other ports on the flight, she confirmed they were not working!

It was good but my seat was terrible for a long trip, too small

Seat layout, flight/club attendant service, food variety and quality could have been better. Business class Standard is visibly low compared with 6 other airlines that we have traveled for the past two years.

The flight itself was great… the only problem for me was the flight delayed both departure & connection.. instead of the 26 hrs (long enough) was an additional 4 hours more that took an aim to my body..other than that I’m pleased.

Had to cancel flight due to war in the Middle East, no refund, and insurance wouldn’t cover it!
