We flew we Jet Blue last January. We were able to select our seat at no extra cost, check bagage at no extra cost
They did change the flight times, no very dramatic... We also experienced a 3hr + delay on the day we were leaving, mechanical problems

Once we boarded the gaves us a free movie

and we all received a 50$ vouchers for our next flight.
The flight attends were very friendly and the plane was amazing, brand new, lots +++ of leg room & the seats seemed even wider
Also when you flight with Jet Blue you can benefit from the airline check in from the Disney resort. You check in at the resort, check your baggage, hop on the ME and off to the airport. No need to fuss with the suitecases until you are home!! Big bonus when you travel with 3 kids.
Overall I would fly with them again and would recomand them to anyone!!
I'm looking forward to make use of the vouchers 250$ off our next family vacation to Disney
