Jet Blue Jumpseat (Passenger seat)
I heard that many Jet Blue Captains will allow a CX pilot a free seat in the cabin (not the cabin crew jumpseat). Go to the gate (you must be in uniform) and ask the gate agent who will then direct you to the Captain. It is not against any FAA regulation for the Captain to allow you to board the aircraft for free. However, as we are not on any approved jumpseat list, nor CASS, getting on the plane is far from a definite.
