This was my first flight on Aer Lingus and it was great. The plane wasn't full so I could move to a seat with extra room. The food was pretty good for airline food and the staff was nice and attentive. I enjoyed the media provided during my 10 hour flight. We arrived home early and it's always good to be home!

The food was pretty good for airline food and the staff was nice and attentive. I enjoyed the media provided during my 10 hour flight. We arrived home early and it's always good to be home!

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

It was what i expected. I like the movies you can access from your phone. It would be nice if there was a gluten free snack offered. But I did bring my own snack knowing there would not be a gluten free option

Flight was fine, but not having WiFi was a major negative

It was the most un-special flight experience in my life.

Not good. One of my luggage is missing. And until now they can’t find it

Where do I start!! I was delayed with my flight from Dallas to Tampa. On the way back from Tampa to Dallas the flight was delayed over 4 hours+. I was put on another flight that was also delayed but not as long. Traveling on American Airlines is becoming exhausing.

Dloght delayed by 2.5 hrs . Common theme in my last four american floghts

The flight was fine. It's the satellite terminal that supports American eagle flights is what sucks. There is only one food option and everything there is way overpriced. I mean I know it's airport pricing, but it's even crazier than that. I bought a sandwich in a plastic container for $18.

This was a horrible experience. I’ve experienced several delays at this point and still not home. I was supposed to be home by 8:30 last night and here I sit at 7 am on a plane STILL unable to go home because of American Airlines.

JetBlue worker, Blythe, was so amazing at the DCA counter. If it wasn’t for her, I’m not sure we would’ve made it through. Please thank her!

You should have had Wifi to make it much enjoyable.

It was fine for what it was. It’s not luxury travel but it was efficient, for the most part. Having my carry-on transferred into luggage however, was unwelcome.

Boarding process was terrible. No assigned seat until the gate, then a long line to get seat assignment.

The space between seat rows seemed to be larger than other airlines. I didn’t check their food or entertainment since I slept most of the way. They do seem to have a lot of options for purchase though.

Kayak sucked. You gave me a confirmation number that was not useable by the jet blue system. Nor did you send any check in emails. I’ll not be using your site again. Nice work.

Given us a free miles or free flight for waiting for 9 hours I didn’t get home till 5am in the morning and I was supposed to be home at 9:30 touch down.

Jet blue was great But the Jayak system Wasa pure nightmare and wasted so much of my time and energy by not giving me a way to access jet blue to check in the flight back I didn’t even get the number confirmation code 24 hours before. Because I didn’t receive the email with the confirmation code I could NoT CHECk IN. I spoke to a kayak third party and they informed me I could not carry a carry on, on the flight which caused me so much extra stress it was just too much. You can be sure I will not be using it recommending your site. Again.

My experience with JetBlue was fine BUT I am very upset with Kayak! JetBlue had delayed our scheduled departure by an hour and you NEVER notified me of the change. I did not hear directly from JetBlue because the trip was booked through Kayak, a mistake I will not repeat. Your reminder of the our trip last week still had the WRONG departure time. Our return trip has also changed, and again no notice from you.

Boarding was quick and efficient. The flight crew were friendly. There were limited food options available on the flight. The pocket guide said there would be salad and sandwich sections available on flights over 3.5 hours. The only food available were snack boxes. And those were limited as well. My flight was over 5 hours. The entertainment system worked well. I had both extra legroom seats and regular coach seats. The seats were not very comfortable. The entertainment controls in the armrest made it difficult to rest my arm without changing the channel on my neighbors TV. Overall, my experience was mediocre.
