Great. Loved that there was WiFi on flight to keep in touch and excellent service of beverages and snacks.

Flew business class. Everything was excellent. No issues at all. Not very many “good” movies to choose from. But lots of mediocre ones

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

Terrible. Flight was cancelled due to the weather in the east and sout east(florida). Did not get any compesation of any kind. According to them, it was not under their control so I lost all the money paid for the 2 fairs from Raleigh, NC to Orlando, Fl.

great flight. Pilot was communicative, flight attendants were excellent. Really nice experience except my tv didn’t work.

The best experience that I have had traveling with JetBlue!

Overall, the flight was better than the flight I took to go to Florida, which had a bunch of problems. The crew is really nice and the plane was new so it had a small problem when we were on the runway, but the flight itself was great. They even made some time back up, which is always a good thing.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

It took an hour to get my bag after landing. Not exaggerating

I had a horrible experience with TSA at the airport. I had to go through TSA several times as there was some issue each time with a piece if clothing I had on. It was so busy & chaotic that I ended up forgetting my Apple laptop at TSA. It’s been days & I can’t get through to anyone to get useful info on how to get it back. I’m very angry because contacting lost & found shouldn’t be this difficult. Employees should know what is going on at their place of work. It seems no one knows as everyone’s answers are contradictory, or you can’t speak directly to anyone as the calls are automated. Very upsetting.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

So so. Terrible aircraft choice for that leg of the flight.

Our seat tv didn’t work All the rest was perfect

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

Meals were adequate but could be better. Lots of movies, podcasts, tv shows. We really enjoyed using our personal headsets highly recommended. 15 hrs flight great to travel at night.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

amazing! they were so kind and allowed us to sit on empty seats so we could stretch our legs and sleep good. Food is amazing as well plus dessert in the middle of the flight!

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

American Airlines canceled the flight twice and was unable to facilitate a change of city for us after our travel plans became affected. We lost alot of money due to this and it seems like the airline was trying their best not to facilitate this. Mind you, I am a very loyal member.

My luggage never arrived in Miami; still waiting a day later.

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Service and food are good. However, main cabin with the extra cost one pays could be better. I don't see any difference with the rest of the seats in the regular category. The seats are too close to the ones in front. For short flights it is Ok, but for long ones there should be more space.

As with every airline the seats are not built for tall people.

Flight was delayed by well over an hour. Communication was terrible.

Fast check in, easy to navigate, crew were very good, the plane was delayed due to a previous flight and I found the cleanliness a little lacking but overall it was fine

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

My wife and I paid for seat selection to be together. My wife and I were on separate rows and the excuse they gave was they changed the plane. Also, I have celiac and asked for a gluten free meal in the ticket profile which they did not have.

Seats, comfort level ugh. Crew was not attentive, only to coach

Pros: they tried to accommodate bc they forgot my gluten free meal Negatives: The flight was freeeeeezing Iberia didn’t communicate my gluten free meal

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.
