Also, JetBlue was created by David Neeleman with 1) no unions and 2) under the old duty and rest rules.
That allowed the airline to keep costs low by extracting more labor for less pay from everyone, pilots and inflight. (Everyone except the ELT, haha).
Then came 1) Part 117 and 2) the Union, and pay scales to match.
Those two things negate the Neeleman model, however JB has been in deep denial about this until, maybe, now.
