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.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

From the start everything was perfectly fine. First meal was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast. Staff were fantastic friendly nice they came round and check we need anything else to eat or drink

After 14 hour delaybwith departure time changed 9 times then announcing the flight was canceled. Another later announcement said the cancelation was in error. Also after paying a higher fare to leave in the afternoon then departing at 4am was not right.

I cannot say this enough, I NEVER BOARDED OR HAVE HAD ANY TRAVEL IN THE PAST YEAR. However your app says ive been traveling a lot lately. GET REAL HUMANS TO GIVE CUSTOMER SUPPORT.

late lack information taney changed my sit even after i had checked i. a day prior and had been at airport checked in for 5 hrs. i have medical condition that i need to sit in aisle but changes to window. only apparent at boarding and they had no explanation why they changed my boarding pass and had no other seats. very bizarre, uncaring and disrespectful. Made my trip very challenging I should sue you. will NEVEr fly JB again. Ever. Would have blasted in social media but did not want to disclose my medical disability.

The plane smelled bad, the temperature in the plane was over 75 with times over 80. Jet blue tried to mask the smell of armpits married with butt. Overall mediocre. Crew was nice

Our actual Flight was great & smooth but it was delayed for 4 hours and Jetblue weren't able to accommodate us in the earlier flight. That was Awful. I lost work/clients because of this delay

Safe takeoff and landing Better snacks and coffee. Headphones for the TV monitors.

Theres several thing i will like to mention and please share this feedback with JetBlue. I was concerned that the food options were limited. Theres no vegetarian options on the sandwiches that they offer on board. Vegetarian options are limited to only cheese and crackers,. Specially on mid day flights there should be more options offered to people. Second comment is that during the flight I watched TWO movies without audio, I tried a few ear sets to listen and none of them worked. Its a shame that they were good movies however no audio. Maybe updating the auxiliary cable and making Bluetooth connections on media will be great. Finally, the bathroom on the plane looked like they needed an update, being remodeled or changed. They look dirty however they are not. Maybe changing, replacing some pieces and updating the air filters will be great. This is not an aesthetic recommendation however a necessary one.

No wifi, not even while close to the continental US or Puerto Rico, no entertainment whatsoever (TVs not working). Totally disappointing.

No entertainment, no WiFi, not great seats. Crew was good.

Cons: "JetTV only had 3 movies and they ran on their schedule. Was not on demand"

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

EWR terminal C United Club is great. Flight and everything else mediocre

Flight delayed for 2 hours due to a part. The plane sat waiting for boarding for a long time and during final preflight inspection the issue was found. Why not do the preflight inspection sooner if you know the plane is being used?

Very bad , airplain had problem with engines , had to evacuate, had a delay on my trip for almost 4 hours , lost my rental car in london..

There was a delay that was unexpected. The seats were uncomfortable for the length of the flight.

All good, useful to have the united app from check in to boarding

It was a great flight, great crew, excellent service, fantastic brand new place, overall 10+ on the experience! Thank you.

Everything was good, hard to really comfortable on a flight that long.

Worst and most inattentive in-flight service I've ever had.

Horrible. Delayed on both planes several times. No attempt to fix it
