I tried to book a flight with Jet Blue. Your third party company hijacked my attempt with a website that looked like I was booking with Jet Blue. I realized it when I paid. I tried to cancel and was told by a man in India that there were no refunds. $735 stolen, Thanks Kayak!

I tried to book a flight with Jet Blue. Your third party company hijacked my attempt with a website that looked like I was booking with Jet Blue. I realized it when I paid. I tried to cancel and was told by a man in India that there were no refunds. $735 stolen, Thanks Kayak!

It was inexplicably canceled and we are stuck in LA, haven't gotten home and it has been an inconvenience having lost work (on unpaid leave for my husband).

I like everything. Blythe at DCA is the absolute best!

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!

They lost my luggage and refuse to help. Terrible airline. I've never experienced worse customer service in my life. Pretty much just told me too bad that I lost all my luggage, not caring that I am stuck in Europe for 2 weeks with absolutely nothing.

You should have had Wifi to make it much enjoyable.

The flight out was delayed from 3:40pm to 5pm and again to 8pm. We boarded after 5pm, had to disembark because they could not get the Engine started, then we switched gates and got a new plane and did not board until after 8pm.

The flight was delayed after already taxiing from the gate due to a malfunction. After 3 hours we were told the flight was canceled. The next flight available was Sunday. My daughter and I stayed overnight in the airport due to this issue. I was given a $12 meal voucher. Unacceptable

Whole experience was poor. Delayed 2 hours. Lied about the delays. Was all jet blues fault and tried to blame on air traffic control. Sent out other let trips and wouldn't allow people to switch aircraft.

My bag was not loaded on my flight. it was not communicated to me until i was waiting for my bag at my destination. there was no confirmation of when my bag was arriving and no way to track it.

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

Lady next to me was coughing profusely the entire flight, other lady moved seats because of it, 8 hours of that during an overnight flight is a bit much.

3.5 hr delay leaving Pittsburgh, notifications for which were incomplete and untimely. Connecting flight was automatically switched to one requiring more than a 30 hour layover! After waiting in a long queue, customer service reduced layover to 11 hours and also set up an earlier standby. The standby had empty seats, but the gate agent couldn't change our tickets! On top of all that my luggage was lost and has yet to even be located, much less returned 5 (FIVE!) days later. Too bad there's no rating below poor.

Canceled flight late London to Florence. Help at airport very poor. Treated poorly. Had to sleep in the airport. Lost bags- still do not have them. Horrible. I should be reimbursed!

The seats are extra cramped if you are taller than 5’8! Spring for the extra legroom seats for sure if you have a long flight!

Very disappointed with British Airways. It has been over 24 hours and I still have not received my checked baggage or any proper update. Customer support has been unresponsive, making the situation even more frustrating. Poor baggage handling and lack of communication seriously impacted my travel experience.

Flight was good but temp in the cabin was cold.

I like American Airlines and their safety record. They provide quality service and a feel safe enough to prefer American Airlines over other carriers even if I have to pay a little more.

Cancelled flight and re booked seats were a downgrade. British Airways said the upgrade was t available but when I checked it was but then they wouldn’t make it right

Boarding was orderly, pilot and flight attendants were nice, entertainment options were good, and low sodium meals were quite tasty.
