Flight was constantly delayed with significant changes in time, it was supposed to get to Colorado Springs at 8:30 PM but it got there after midnight.

I don't know why flying out of Sarasota requires two plane changes.

Plane was late. Zero service for 2+ hour flight and it was not that bumpy.

Great flight. Good snacks and drinks. Grateful it was free. The flight from Nashville to louisville, i think her name was Tracy (not sure that's right) super awesome, nice and cheerful. She really enjoyed being at work today! She was the person who scanned the boarding pass on flight wn941. She should be recommended for a raise !

I elected to pay for the upgrades and found very little difference

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Because of storms in St Louis, plane was diverted to Kansas City. After about 1 hour stay went back to st Louis to finally reach distanation. Made for long day. But southwest took care of us. Can't fight mother nature

Worse experience especially since there were delays and unreasonable accommodations made

Initial flight had an engine overheat - returned to DFW. Had another plane ready, but crew timed out. Had to wait 5h for boarding. Fully boarded and pilot says plane is not flight worthy. Deplane and go to the other end of the terminal. Wait an hour to board third plane because the crew couldn’t leave the second plane because no wheelchairs were brought to remove passengers. Finally take off and there is no catering (in flight service) even in first class. Very much an AA failure.

We were delayed due to a mechanical issue, but the gate staff and then later captain were giving thorough and frequent updates. Ended up being delayed about an hour, but we did get out, so it was overall a good flight!

My flight was delayed twice. The first time because of “plane maintenance” and the second because the previous flight who supposedly “arrived early” took an obnoxiously long time to get off the plane. Total delay was over an hour for no reason. Not to mention your airline repeatedly changed our gate from one end of the terminal to the other. Not very happy about this experience. My previous flights with American haven’t had this many issues.

We’ve had a year of delays with American, and this one was another flight to add to that list. It just reduced our vacation by a day! So frustrating. In-flight entertainment (TVs) weren’t working, There was no drinks service due to delivery issues.

This flight moved Gates several times in a short time period, from B to C, which required a substantial walk or rail ride. Then the flight was delayed more than 2 hours and the food was subpar compared to other flights.

Flight cancelled. Twice. And no communication. No gate agent. Went past boarding time and had to go and see email from AA. Airport communication was bad

Improvements in communication and empathy are absolutely necessary for American Airlines staff (top down). It’s like they are numb to the needs of their customers.

Flight delayed, boarding time kept changing, not good. Nee firm information given each time.

I did like the employee's, they are very friendly and all smiled most of the time, Overall, from checking in bags to getting on plane, not enough employees to be able to get all on the plane, therefore I was not able to get on the plane, due to no one wea there for me to check in my bag, so I decided to go thru the security point and by the time they were done with my bags, I was told that my bag cannot be checked in, and then found out that the lady that does the check in was boarding the customers onto the plane, she said that she was going back and fourth, there for was not able to get on the plane, which changed all my flights by the time I got to Dallas, I was on standby 3 times, and wasn't sure about being able to get on the fourth plane, so ended up buying another plane ticket, so I could make my destination on time.

Not sure about entertainment as I didn't use any, so maybe there should be an NA option on this survey. Otherwise everything was just as it should be. Of course I wish planes were more comfortable and had seats that would tilt back further.

The flight kept getting delayed, but the ground crew did not communicate well to the passengers in the terminal. First, we were told that it was an engine issue. That was understandable. We asked, after the third delay, if it would be canceled; they reassured us that that would not happen because a new plane was on its way from Washington DC. Four hours later, that is exactly what happened. No announcement was made only people who had the JetBlue app learned of the cancellation. They rebooked us on a flight that would get into our destination 36 hours after our original time I had to spend an exorbitant amount of money to book an additional flight with a different airline, the following morning in order to make it to my conference in time. Not to mention the fact that by the time I discovered the cancellation on the departures board, it was too late for me to receive a refund on my lodging in the destination city for that night. Because I had booked with KAYAK, I did not receive any JetBlue email with rebooking information. This is what the information information desk kept telling everyone who inquired about a rebooking. This was my first time flying with JetBlue. Needless to say, after extremely poor communication andover $1000 of additional expense later, I will not be flying with them again.

We were several hours delayed due to confusion during boarding. Evidently the crew could not match the manifest with the boarded customers. After significant time trying to find individuals on board, a crew member walked through the entire plane re-scanning each of our boarding passes. Then we had to wait for a new slot to depart, and when we landed, our gate was not ready. It was a complete goat rodeo from start to finish.

Flight is delayed by more than an hour without any reason, the jet blue gates kept changing every 20 mins and there is no proper communication. No ear phones provided in flight, there is a screen with entertainment but what is the use, I have earphones but the console has outdated audio connections, no usb C or bluetooth, they are living 15 years behind

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.

Flight was cancelled, no support at JFK even though it is their main hub.. wait times on the phone was very long

I liked the punctuality, the crew, and overall the whole flight

Separated a pair of family members(father and teenage daughter) on all legs of the flight that were booked together, just to create an upsell. Food was horrible and only catered to vegetarians and gluten free crowd. I’d rather give more of my money to another straight shooting airline.

When I agreed to give up my two seats because of overbooking by the airline, I should have been offered some sort of reward or credit towards a future flight. I was not. It was not until the next day when I mentioned it to a Jet Blue employee that I was advised to call 1-800-JetBlue. So here I am, having done Jet Blue a favor and I had to do the work to find out if I was going to get a credit. Such service

A nightmare. Scheduled flight delayed 2 hours then cancelled because pilot timed out . Unable to find another pilot. Really?! Weather certainly a factor, but JetBlue seemed totally unprepared for the chaos that ensued when flight routes were cancelled. More cancelled flights, finally many of us who had been bumped from other flights were allowed to board a Boston bound plane around 3:00am, delay after delay, sat on tarmac for another half hour while pilot dealt with weight distribution issues (?), arrived in Boston 4:30. Crew were wonderful- same attendants all day and night and they were exhausted. Fortunately for me and my son that Boston was our final destination, not so lucky for many who missed connecting flights.

Jet blue just had great service overall! Only a little turbulence heading out of Austin, otherwise the jet stream helped the speed of the trip!

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

Would be great if Frontier can Assign Seats together under one PNR

Boarding was organized and flight was on time. Overall very satisfied with my flight.

The boarding gate was in Terminal D, but the Frontier counter was in Terminal E. So I had to move back and forth between terminals to check in my luggage. This was the worst experience that I had in terms of flights.

My departure gate was E10 but no kiosk at E10 for check in & no one to ask. A United attendant helped direct us to E38 for check in. The kiosks at E38 were all malfunctioning. A counter agent had to check us in. We then had to walk back to E10 for boarding. E10 to E38 at DfW is not an easy trek. No where in all the info they sent us indicated there were issues to over come. They can cut only so many corners. Luckily we arrived plenty early to deal with Frontier’s inefficiency.

Horrible, first and last time that we use frontier. Kept us in Las Vegas for 8 hours. We boarded original flight at 2 pm right as we were getting ready to leave we were told that plane had issues. Stayed in gate and then after a couple of hours we were told that we were being assigned a new plane and were moved to a different gate. Then after 3 hours they said that the plane had issues and after a while of just being delayed it was cancelled. Thankfully there is southwest that came to rescue. We purchased ticket and left Vegas at 10 pm
