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

The seats were roomier than other airplanes I’ve been on.

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

No included food for a 5 hour flight and the entertainment was only accessible if you had wired headphones (not provided). Otherwise though, great and smooth flying and customer service.

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.

They have the most inexperienced / rude flight staff I’ve encountered

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.

They gave away my business class seat. No explanation and no apology. Told me I had to take the downgrade if I wanted to get to India. Then no WiFi for 10 hours. Just ridiculous. We should not work with this company at Deloitte. They don’t know how to run a business.

Work being done at DIA made it difficult to find BA desk.

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.

So very uncomfortable! The seats were dreadful and the space in a middle seat was too small. I don’t know what I would have done if I were 6 ft. Tall. I feel like the airline deliberately made the seats so close together for the purpose of selling the more expensive seats. Economy is on thing, but there should be a minimum standard of care. The meals were taste free and soggy. I can choose not to eat the meal, but I was trapped in the seat- so overall the lack of seat comfort is the biggest issue on such a long flight. I have flown overseas British airways, although about 10 years ago, and it was a fine experience quite unlike this flight.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

Baggage took two hours to arrive in hall after landing.

Do not book through Kayak with connecting flights. You have to deal directly with airlines if there’s a problem. Our business class BA Flight was delayed 2.5 hours. This delay would have caused missing flight to Aman airport. We had booked business class and BA scheduled us on cattle class in last row on American. Even thou there were comfort seats available. Beware

I like the way they are friendly and helpful . More food options.

Flight delayed at the phoenix location itself. Missed connection flight and the alternate route given was 1 more extra day. It was a horrible experience
