Multiple delays due to weather in Chicago, but the crew did their best to get flights rescheduled and on to their destination. I felt like the crews handled a frustrating situation very well, kudos to them! I was very glad to not have a cancelled flight.

Multiple delays due to weather in Chicago, but the crew did their best to get flights rescheduled and on to their destination. I felt like the crews handled a frustrating situation very well, kudos to them! I was very glad to not have a cancelled flight.

Southwest’s point to point system caused a 2 hour delay due to the crew being late from their inbound flight. Also, the WiFi and entertainment didn’t work on the plane.

A) Checked my luggage at the gate but never got to pre board B) if we are helping with checking our carryon and waiting 40 minutes for it we should have some privileges c) luggage took 40-45 minutes to come.. d) I asked for another snack and was told the plane is full.. seriously a small snack

I like the staff members they were super nice and helpful very sweet people :)

Boarding process of asking for volunteers to check bags goes against the system you had before with 2 bags checked free. This process is more of a guilt trip than a caring attitude toward the customer. In addition bag-size scrutiny has increased which also slows down the process of boarding. My wife said she will not fly on your airline again unless there is no other option.

Overall good, just screaming kids in the area the whole flight.

OKay. I sat in the back of the plane and it was really loud between babies and little kids, and adults who.like to talk a lot and loudly most of the flight.

The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

One of the crew performed a hilarious skit to accompany the standard instructions. Passengers enjoyed it so much they applauded at the end!

Long delay due to mechanical issues. They should have just swapped the plane and not make us wait while they figure it out. Disappointed

Takeoff delayed 2 hrs. Boarded on time to find we were missing part of the flight crew. Then informed that they had loaded too much fuel. Spent 1 1/2 hrs sitting there burning off the excess, which included a couple of laps around the runway until we were light enough to fly! Ridiculous!

I especially enjoyed having a lightly packed flight which enabled me and my wife to occupy a three seat area with nobody in the middle seat.

The seats are very small, that is all the staff did a good job.

It was great. The staff is always helpful and polite. The app is great and makes the whole trip and process so easy. They even offer a step to step guide to your correct terminal. And they keep all the information you'll need updated. Anything you can think of! Great experience.

Price was crazy watch it if you Chan he your flight

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

Plane was so old it had cigarette butt trays in the seat

I am always very pleased with the service u receive from JetBlue employees

Your Jet Blue representative at the check in desk in Boston on Sunday morning, October 13, was unkind and unhelpful. For that reason alone I will avoid JetBlue airlines in the future. No food or beverage on the flight due to turbulence (not your fault). However I paid extra to sit in the upgraded section in the front and did not benefit from most amenities.

we used to fly with a different airline but it shut down. We had to find an alternative airline that we like in order to make domestic trips and this fits the bill. Not only is it a similar price but the customer service and the experience overall is much much better. We will be using JetBlue again.

Uncomfortable seat. No help for my disability. Staff refused to help me put my carry-on in the overhead bin. So I had to check the bag.

Terrible. Quality has gone down significantly. Plane was delayed. No instructions from the staff. Will try to avoid in the future!

The flight left unexpectedly early. Although I checked in at the gate, the crew made no attempt to contact me to inform me that what had been a delayed flight was now departing before the scheduled departure time. No announcement on the PA, no phone call. When I checked back at the gate for the delay status just before the scheduled departure time, I was told the doors were already locked and the flight had left.

Late boarding, had to check the bag even though there was space on the flight and I was I row 7

Fabulous! This was the first time we've flown with JetBlue and the entire experience was flawless!

Horrible. Flight was cancelled, jet blue app not working to rebook, no phone number available to call Jet Blue, 400 ish people in line for the help desk, stuck in Boston for 2 more days had to book new flight with a different airline and still not sure if I will be able to get any refund.

The pilots were awesome and got us there early. Great landing too. No complaints on the flight. Service - a young cabin crew woman was terrible as she seemed to hate her job and never smiled. Why do they hire people like that? Terrible. The cabin crew lead woman was wonderful - very professional (and more mature go figure)

Crew were helpful, pilot kept us informed about turbulence, snack choice was awesome!

It was one of the worst I have ever had. The plane was over booked, and I did not have a seat. When I questioned why because I had booked this weeks in advance. I was brushed off to be advised they are trying to find someone to give up their seat. Only to be advised I would be boarding last. I had priority boarding in group 1-4. When I asked why I had to be last because that is not what I paid for I was advised it doesn't matter you will get a seat. The ticket person was very rude and unprofessional. The gate changed several times and it was going from one area to another area far away from where we were at. I feel like I should have been compensated in some kind of way because of the way I was treated. The ticket agent acted like it was my fault that the plane was over booked. Not one time was I apologized to for this inconvenience.

I have posted the comments in the first flight leg.

First class snacks - stewardess gave out multiples to everyone until there was almost no selection left when she got back to me last in first class cabin. Nothing left that I would eat.

My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.

The WiFi was out gr entire flight. Had to Diane for almost 1 hour to wait for a gate to open up for plane to dock. Very bad experience.

DELAYED AGAIN and AGAIN and AGAIN - not only that, you delay in 20 minute increments for hours and hours instead of having an accurate delay understanding.

AA was fine....the overall experience was subpar, but not due to the airline due to broader issues

No ground air conditioner for the plane. Very hot and humid prior to take off which was an uncomfortable period of time.

Because I can’t stand very long in one place, I was allowed to reword.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

Better than expected. Staff were friendly and nice on both flights.

Just know that everything, and I mean everything is “ala cart”. 60$ just to put something in the overhead bin. I will never fly Frontier again nor do I recommend them to anyone else.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.

I didn’t have enough time to catch my connecting flight and had to use a different Airline. I will be requesting a refund.

I brought a ticket and car rental through Travelocity. There was no where to add a KTN. So I thought i’d add it by looking up ticket on frontier website. I tried 3 times with the frontier chat bot to add my KTN it never updated my boarding pass. So then I tried showing up early to do it in person at the airport. The first employee update my ktn in the system and gave me a new boarding pass. I was sent back by tsa to join regular line. Then I was told to add my Ktn. It would cost me $25 extra. Given the length of the cue I did pay. Congratulations! BUT I will NEVER fly frontier again. Plus the plane was very old. It had actual ashtrays and old looking tray backs. Worst travel experience ever. Im warning my friends and family not to use frontier ever.

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.

Was just ok with over selling I guess. A lot of people in a short space and when we finally arrive i20 minutes, waiting to get out from the plain because we were waiting authorization for out boarding? Something like that.

They changed my flight and did not want to accommodate me or try to help me in any way. They do not care about their customers.
