Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

It was extremely hot in the cabin the entire flight, vent air was worn

It was perfect! United Airlines staff was extremely caring, super friendly and professional

Food is very bad and entertint not too many options ... flight attendet service is not good

For a 17 hour flight, they kept us well feed. The music selection could be better curated. The entertainment selection was about what is expected. The crew was fantastic.

I forgot to pre order gluten free on a 16 hour flight and I am pretty sure the crew raided their own lunches and first class to keep me fed.

JetBlue cancelled the flight along with hundreds of others, for no apparent reason. no recourse, no rebooking options. never booking with them again

Jet Blue cancelled my flight after I had boarded. They attempted to rebook me for a new flight two days later. I was able to rebook with a different airline, but not until the next morning. As such, I was forced to get an expensive hotel and missed important work meetings Monday morning. I am very disappointed with the customer service and will be pursuing full reimbursement for my hotel cost.

You did a great job rescheduling my cancelled flight. However, you made me pay for two seats for $118 even though the seats on the original flight were free. I think that was a very unfair thing to do.

They cancelled the flight after 5 hours at the airport and the only flight they offered was for the next day with a 7.5 layover in fll. This was not going to work for me as this was only a weekend trip and getting into providence at 10 pm a day later caused me to lose Mo ey on hotels money on airport parking a dog sitter etc. they wouldn’t offer any type of a voucher or anything else. All they did was refund the flight which didn’t help me with all the money in time I lost. I was going to see my very sick father

The flight was on time the crew was courteous that makes for a good flight.

A more comfortable seat. Padding would be really helpful but I've read the airlines don't want customers to be satisfied with economy seats.

When I booked, I included my checked luggage and when the bill was sent there was no record of this. Its was costly since I am from Trinidad amd Tobago. Exchange rate over seven dollars to one US dollar.

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

Flight delayed 4 times on a non-stop from BOS to SFO. Then when landed in SFO had to wait for 30 mins for a gate AT 3:30AM.

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