Everything went very smoothly I loved having the earphones and the blanket and the staff was just super friendly

On time departure and arrival at LAX - good inflight entertainment - all basic seats on every airline right now begin to feel small after 10 hours!!

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

On time, only a little turbulence, very competent and caring attendants. Clear information.

My issue is with the SkyWest terminal. The flight was not listed on the main airport flight screen list, and I had to do a Google search to locate the terminal and gate. We had to ask several airport employees where to locate the phantom gate. The airport did not provide adequate signage and was confusing. When we arrived, there was one vendor providing services that quickly closed, leaving zero options for food and drink while we waited hours for our delayed flight. The crew that assisted with check-in and boarding was VERY friendly.

No complimentary drinks or snacks offered on a 2 hour flight was disappointing but everything else went well

I love the direct flights. It saves a lot of hassle and allows immigration and customs in Ireland, making arrival much easier.

So, the trip from Dublin to LA did not really happen because the flight took off before we could finish the transfer.

The seats needs to be comfortables, at least please add more padding to the seats.

Not JetBlue's fault but Aer Lingus never explained how to transfer to JetBlue.

Thought the economy premium experience would match that of the Amsterdam to Boston flight. Aircraft was older: chair didn’t lean back. I had to buy a blanket, which on the flight over was complimentary. Flight crew seemed disinterested all around.

The plane was filthy and worn - the seat pockets were stuffed with tattered food and torn pamphlets. The cleaning crew that came on as we were deboarding were grabbing handfulls of trash and perfunctorily wiping down tables with dishrags. It's been a while since I flew Jetblue and it used to be a great experience. After this flight I will avoid flying Jetblue again if there is any alternative.

JFK is the worst airport and JetBlue is the worst airline

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.

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.

Great price, easy check in, love the free drinks and snacks, and nice crew. The only negative part was waiting for your seat assignment 5 minutes before boarding, and the seats are a bit uncomfortable.

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

Everything was good instead change the gates! I missed my first flight because it was changed the gate and I didn’t know!

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

The guy sitting in front of me kept pushing hard his sit against my legs… very uncomfortable

Awful! We boarded and then sat on the plane for 50 mins before having to deplane due to a maintenance issue which should have been addressed before boarding. Then we had to change terminals as there was no other plane for us at the current terminal. Then we waited another 2 and a half hours to board again only to wait for 50 mins on the plane again for the snacks to be brought from the broken plane. And once we were on the flight we still only got the complimentary cookie and soda or water. No food vouchers provided even though we had waited over 3 hours for our flight.

The seat when "flat" was not flat and pad was too thin to cover it.

Delayed for mechanical and no updates on what was happening and how long the delay might be.

We are too tired and frustrated to comment politely at this point

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

The service and food needs to improve to catch up with other international flights

The flight crew was fantastic! Which the seats had a small TV.

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q
