There was a loud squeaky sound the whole time we were flying.

6.0 GoodEliza, Apr 2024SAN - LAX

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

I was sitting at comfort +. One of the Asian male crew was so loud when he delivered service. When he asked questions or what food you need, he was shouting. He must be a prison guard before going Delta.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Space and comfort was good. Staff could have been more helpful and friendly.

Crew was not friendly when I went to request a seat change.

I cannot say this enough, I NEVER BOARDED OR HAVE HAD ANY TRAVEL IN THE PAST YEAR. However your app says ive been traveling a lot lately. GET REAL HUMANS TO GIVE CUSTOMER SUPPORT.

late lack information taney changed my sit even after i had checked i. a day prior and had been at airport checked in for 5 hrs. i have medical condition that i need to sit in aisle but changes to window. only apparent at boarding and they had no explanation why they changed my boarding pass and had no other seats. very bizarre, uncaring and disrespectful. Made my trip very challenging I should sue you. will NEVEr fly JB again. Ever. Would have blasted in social media but did not want to disclose my medical disability.

The plane smelled bad, the temperature in the plane was over 75 with times over 80. Jet blue tried to mask the smell of armpits married with butt. Overall mediocre. Crew was nice

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.

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

Our actual Flight was great & smooth but it was delayed for 4 hours and Jetblue weren't able to accommodate us in the earlier flight. That was Awful. I lost work/clients because of this delay

My experience with Eva sir was good except the long walk in LA Lex, that was inconvenient for my age,

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

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.

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.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Quit making seats narrower and narrower. The guy beside me spilled over in to my seat.

The service was non existent . Crew did very little didn’t even answer call button . Premium economy in this long haul was the worst I have ever experienced . Never again flying with them .

The crews are great.. Easy boarding. Inflight entertainment ok. Food is a disappointment.

The real big issue with this flight was that it was 3 hours delayed. Other than that, no big praises or complaints.

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

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!

Seats in coach aren't padded enough for a 6 hour flight

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.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….

See my previous comment which is mostly about our flight from Phoenix to SFO

Pro: The stuff was great. Friendly, patient and caring. Our seat row was clean. The bath room was clean. Our flights were close to on time. Con: The leg room is too small. No blankets or pillows. No entertainment devices at all. I can’t remember to have a food choice. I would fly again with frontier for short distances.

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!

4 hour delay because they used our aircraft to fly a different segment (per the captain)

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people

absolutely horrific. delayed flights, overbooking. over charging. nightmare service beyond words. stay away.
