The flight is actually a redeye from Dallas to Miami...though your right...not long enough to warrant a redeye. Oh well. Maybe it leaves DFW
at 2AM? (I know in the storyline the plane is delayed because of weather).
Most of the filming for the movie was done in Los Angeles, except for the finale, which was filmed in Miami and MIA
And looking at the trailer, the name seems to spoof on jetBlue by being all "modern" and lower-cased.
