Kayak booked this flight with only 1h 20min layover in Chicago. This made it impossible for me and several other passengers to reach this flight. Moreover, the gate closed boarding in spite of several passengers still on their way without waiting even one more minute. However, the plane departed with 20min (!) delay, i.e., there would have been at least 15 min time to let the delayed passengers board without causing any delays. I complained and as a "thank you" the attendent booked us on the last (!) flight to Indianapolis ~7h later! Thankfully, I caught the spitefulness and the United customer line rebooked the flight to an earlier flight. Although I can't grade this particular flight since I never had a chance to take it, Kayak made the mistake of a too short layover and the crew at the gate was awful.

Flight did not have wifi service. It was experiencing technical difficulties. Definitely and old plane that needs updating.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

Very thoughtful flight attendant offered me water immediately since I had run to make my connection.

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Food choice was poor and we had to buy on board snacks.

The flight was delayed by about an hour due to a maintenance issue which later then required a change of planes. The crew was great and friendly. The in-flight entertainment did not play properly on Apple Vision Pro in a Safari browser. Although the movie trailers would play fine, the actual movies themselves just had a black screen with audio. There must be something with copy protection or something that isn’t compatible with the Safari browser on Apple Vision Pro. The free inflight Wi-Fi for American Airlines Advantage members is a nice bonus. and is great that they aren’t charging extra for things that have become basic utilities in 2026, like internet access.

Good flight, regional jet so old and seats could use an upgrade

Couldn't make the flight because connecting flight was canceled.

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

Maintenance took a very long time and then we were in a holding pattern. While a one-off maintenance issue is standard, there were delays on both of my flights for this trip based on maintenance issues with the planes, which delayed both flights over 45 minutes. Thankfully, I didn't have any connections but it wasn't an experience that would make me pick AA if I have other options.

After we'd boarded , they canceled the flight. The crew didn't even know , we just all received text messages. Then after they deplaned us , AA was just like "too bad, go F your self, we sure ain't gonna help you"

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

I don't like that I have to pay if I want extra leg room. The seats are so expensive; I sit in normal seats and my legs and knees cramp the entire flight. I never feel comfortable on AA flights.

Crew at first tried to SELL snack boxes (for an hour-long flight?!?), and it was the only leg of four on which I was charged for a hard seltzer. 😕 Spent extra to select seats in Row 8 for quicker disembarking only to be seated in Row 25. Someone owes me $38 for that!

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.

My checked in luggage cost was $59, almost ticket price. The first 13 rows were empty, but fly attendant did not alow women with little boy change her middle sit, sweet boy was crying, I am so sorry for mother and passengers. At the end of the flight the cabin became impossible cold. Only good was timing of departure and early landing, but it suppose to be normal.

The gate attendant in Boston had a high raspy voice and spoke much too fast to be understood. Not pleasant.

Flight was quick, less time than expected, and the attendants all friendly and helpful. We had paid extra for more leg room and were very comfortable. Haven't flown JetBlue in quite a while. Glad to be back!

I specifically choose not to check bags to ensure I can proceed directly to ground transportation upon arrival. However, due to a recurring lack of cabin space, I was again forced to gate-check my rolling luggage after going through my luggage to take out electronics and batteries. This practice unilaterally changes the service agreement made at the time of purchase. JetBlue needs to find a better way to manage overhead space that honors the carry-on baggage allowance.

Both flights were significantly delayed. The flight experience itself was great.

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

The free wi-fi was great. But, the flight delay was not sustainable. It definitely impacted people schedules and JetBlue didn’t do anything to compensate clients for it

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

During the flight I suddenly felt very sick, and no one from the crew even tried to help me or check on my condition. They seemed completely indifferent and showed no concern for my well-being. I was very disappointed by the lack of care and compassion. I hope the airline improves its customer service and trains its crew to respond better when passengers need assistance.

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.
