There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

40 minute delay before take off after boarding flight. Bright lights throughout night flight due Issues with light panels. In flight Entertainment nonfunctional

Another horrible Jet Blue experience. This airline has suffered the biggest decline of all from best to worst. TVs didn’t work (again). internet was temperamental. Boarded late and couldn’t get organized to serve snacks.

I hate their constant delays! It’s as if I cannot confidently make plans for timing when I'm traveling with them. I slept through it, so all I can say is it was good.

There was no wheelchair or wheelchair escort at the gate..unacceptable

From bag drop to boarding, it was great. In-flight is a little different. The seats were a little uncomfortable for that long of a flight. The rest of the cabin crew except for Eva was wonderful. Eva was not friendly at all. I've had to personally encounter her twice in-flight. First time was when I had to go to the lavatory in the back of the plane, and since it was the first for me to board such tiny plane, I didn't know we were using the crew toilet. She was giving me an attitude while telling me where and how to open it since it's not the regular push to open type of door. The second one was when I had to throw trash then use the lavatory again. I asked where to throw them, and unfortunately she was the only crew in the back doodling on her phone, she had to point it out to me with an attitude then told me to wait on the carpet, which I understand because I didn't realize that, but she could have been nicer. After all, I'm a paying customer, and assisting a passenger who isn't knowledgeable about the aircraft is one of the things she's there for. The rest of the experience and crew from bag drop to in-flight were excellent except for her.

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

Boarding process on JetBlue is an absolute disgrace. I can’t believe they can’t figure out a better way to board everyone. They called people with disabilities, mosaic and group A all at once and it was a disaster

We flew halfway to our destination (NYC to Burlington) and turned around due to a mechanical issue (landing gear wouldn’t retract automatically). We turned back to JFK for JetBlue’s benefit as we landed safely at JFK and could've just as easily landed safely in Burlington on our Christmas Day flight. Instead the company directed the crew to return the plane to more easily service the aircraft. The passengers landed 3 1/2 hours later and JetBlue gave each passenger $50 for the trouble. Hardly fair compensation to be separated from family on Christmas Day.

There were weather issues and coding problems whatever those refer to, but JetBlue, for two days in a row was unbelievably late. Several hours late, resulting in almost no sleep for passengers like me.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Nice flight, nice crew but no cookie or napkin with my seltzer.

The flight was canceled. Got rebooked to Chicago and when we arrived our luggage where to there. They were going to our original destination the day after. They would not deliver them to our house. We had to go pick them up.

737 Max was leaking water into the cabin through the windows. Overhead bins opened on landing. Bad bad plane.

Other than the two hour delay, it was fine. Of course they were very professional and kept us informed throughout the whole delay..

Easy boarding in group 2. Landed 1/2 hr early. Delicious cookie snack.

Good. The wife was not working but then it got resolved.

Missed this flight due to delays from my previous flight

Easy peasy. Crew was great. Take-off and landing nice anc chill (good job by the pilot). Thank you UA!

The plane was delayed coming in and on the tarmac. I was coming from another flight so it made for a very long day. The stewardess kept trying to slam the overhead bins closed and I was worried that she had damaged my new luggage. They ran out of snacks and lccdsddd me a hummus box which was nice. It took them a very long time to pick up the garbage so I could not go to the washroom and had little time. To prepare for disbarment. The TV system was hard to control from the armrest and picture wasn’t clear. The crew did apologize several times for the lateness. It took the Denver airport an unusually long time to de-ice the plane.

WiFi connected but only let you go to the AA website, not even text messaging worked.

The flight was excellent, provided that we had inclement weather. We departed earlier than scheduled and arrived early. There was a little turbulence, but nothing to be worried about.

pleased with overall experienced, but seats in coach are tight.

Don't often sit in 1st class. Our experience was great.

The 2 hour delay was frustrating but our crew did a great job getting us out quickly and keeping communication especially with the people who had connecting flights

It was right on time and crew were very courteous

American always delays flight so it stressful getting the next connection

Flight was 2 1/2 hours late and information at the gate was inaccurate and inconsistent with online data.

Nothing really nondescript, the flight attendants were friendly and helpful.

I rarely vote ‘Excellent’ but this AA flight out of LGA was amazing. On time departure, early arrival, amazing crew, smooth flight, baggage came out quickly. It was the best airport/ flight experience that anyone could ask for/dream of. Highly recommend. I usually fly Delta but American Airlines really stepped up their game.

Pretty good. Would’ve been excellent if we would have left on time and the crew wasn’t late.

Spirit airline tries to screw you at every opportunity. Spirit wanted 65$ for an extra pound in the suitcase Made me open the suitcase at the counter to remove 1 pound. Staff very cold and rude Will never fly spirit again and will recommend same to family and friends

Overall it was a good experience. Stewards were very kind and professional. The departure and arrival times were as promised. Plane was clean.

No frills, limited comfort, no food, no entertainment, but fine

The airplane was extremely hot the air conditioner wasn’t working I

Seats horrible. No way of getting comfortable . But flight ran smoothly

Every thing was fine ,low price,easy on time ,clean, good staff, really no issues

Unfortunately not great, my flight was canceled with no notice given. I attempted to reach out to spirit airlines and have yet to receive any correspondence. I then had to book a new flight at two times the cost of the original.

The price is good but I feel that carry-on bag could be a little low and snacks prices

Pack light and enjoy the quick boarding and early departure and arrivals.

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

Our flight was delayed an hour, then when we got to board our flight finally, we were waiting in our seats for take off for 45 minutes before it was communicated that there was a maintenance issue therefore we waited on the plane for over an hour while that was resolved. We did not get to Phoenix until almost 3 hours after we were originally supposed to. This was the first and last time I will be flying Frontier.

Flight was canceled with little warning. Flight was rebooked through Ontario, California and connecting flight was delayed by over three hours. Frontier is living up to their Greyhound of the skies reputation for sure.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight was OK. Seats were good no cell phone charges on the plane no TVs or entertainment.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

Flight cancelled and was told by a rude gate agent that they don’t accommodate on other airlines. Had to wait 5 hours for a connecting flight that had a 7 hour layover. Would not allow bags to be checked early so we couldn’t go through security .Had to rent a car for the afternoon to store bags and get a meal. Also incurred a hotel fee. No apology or reason given for the cancellation- just rudeness.

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

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.

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
