The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

Passengers need to check in big baggage instead of bringing on the plane. That cause inconvenience for everyone. Otherwise flight was good.

Great. Very smooth. Plenty of information. However, wish they would give out a menu in advance of making a dinner choice like other international airlines. The flight attendant says chicken or pasta and there are details about ingredients or spices requiring the passenger to ask which requires the flight attendant to answer many times. So easy to solve this problem. P

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

Late flight caused a missed connection, had to be put on a later international flight without my requested vegan meal.

Half the bathrooms assigned to economy were out of action

The crew members were great. The food was good. Entertainment was average - Could use a wider and better selections of movies and series.

Flight was cancelled after 3 1/2 hours. Support for rebooking was overwhelmed. Lost first class tickets and to fly economy.

I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.

Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

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

Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.

Fight was delayed an hour due to operational issues ,then further delayed due to ground control for a total of about 1.30 hours. Salad was completely frozen and flatware was so cold you could barely handle it. Crew was friendly and professional and the flight was smooth. The aircraft was clean and well-serviced.

Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.

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.

Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!

Crew was great! Food sub-bar, tepid & flavorless. No snack options on trans-atlantic flight. Premium Economy seats ok, leg rest wouldn’t stay in place.

Entertainment system did not function. USB ports did not function. Wi-Fi did not function. Terrible trifecta…

Luggage did not make it onto my plane. Business seats were economy with empty row seat. Just horrible experience. Why would the company allow for transfers that don’t give employees enough time to transfer luggages??

Disliked having to wait a little longer to disembark from the plan when we landed in London

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

Pathetic check in experience at JFK. Everything is self check in. Not enough staff present to help with when the check in process or the kiosk gets stuck. Staff present not welcoming or pleasant at all. On the other hand the NY based flight crew was great. Courteous and friendly throughout the flight. Special meals leave a lot to be desired. Kids meals should be made available when kids are flying and same goes for special kids meals too.

There were several issues with this flight. I have flown quite often internationally and I was surprised by the lack of presence of attendants other than meal and drink times. The food was not best but I feel that is the norm. We also had to get off the plane once in London via stairs and bus to the terminal. Anyone who had another flight had to then get another bus to another terminal. This causes me to miss my flight and have to rebook.

Food was very bad, eg noodle dish that could have hardly cost more than $1 plus a dry piece of bread a sad salad and a fig bar. Entertainment was also disappointing, mediocre movies and Tv shows and barely any classical music.

My seat was dirty. No food for baby available. Crew were wonderful. Early boarding helpful with baby.

Everything was good except checking bags . I had paid for two bags but it didn’t show so we had to do it again while people waited and we were struggling to get to our flight

Plane was delayed multiple times. I would like to request a refund. Was due to arrive Thursday evening ended up arriving Friday morning.

The crew and the pilots. The pilots were amazing. The landing in Cancun was excellent.

The security line at JFK was one of the longest I’ve ever experienced - probably 45 minutes. I don’t know if JetBlue has control over it, but it detracted from the overall experience. Entertainment had good options, but the volume control was a bit small to tap on and the screen had a fair amount of interference blips. Clearer picture would have been better.

I liked the entertainment on JetBlue, the service from JFK to JAX was terrible at best

I usually dont fly JeTBlue and I dont think I will ever do it again. The flight was delayed fee time, nobody was giving us any info at at the airport, gate changing, the slowest and poorly organized boarding ever, rude staff.. huh

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

Excellent price. Everything on time. two bad parts. Kayak said I couldn't sign in for the flight online, but I got an email at the same time from Jet Blue and they let me sign in online. Second bad part was that, although I had provided my known traveler number, neither of my boarding passes, for this flight and the previous one, had TSA pre-check showing.

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.

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

Flight was good but temp in the cabin was cold.

The seats in Premier Economy were very comfortable. The food was better than average. The way British Airways handled our seating was atrocious.

The airline was not clear about a new departure time so we got to the airport early anyway. The flight left early which was great because of weather. The check in process was very easy and staff were friendly and helpful. The crew was great and our flight was very good.

Although business class, the seating was really cramped. The food was so so.

Smooth trip no turbulence which is always a bonus for me lol! In cattle class so an element of being a bit squished (but not as bad as other shorter haul airlines) smaller plane than the one we flew out on and entertainment system wasn’t as modern but still definitely passed the time. Lovely crew x

I was sleeping during dinner service, no one bothered to offer meal later, I remained hungry….until I got a morning sandwich!

Very caring crew on board. Didn’t have dinner as I was sleeping. Was seating in the emergency row so I had comfortable leg room

Although the crew were great and the good nice, I might as well have been on Ryanair for the amount of space I had. Not good enough BA. I’d rather pay more and not feel like a human sardine.

Crew were fantastic can’t fault them at all. Couldn’t do enough for us

They’ve lost my bag and I have no way of really getting in touch with anyone and have received no updates.
