You want to work for JB? Focus on that which you can control. JFK or BOS is what you can control most of the time. I could give a 0.0% about where they “plan” to go.
I can assure you; most United pilots don’t want anything to do with JetBlue.
It's because most of the mid/junior seniority UA guys would see thousands of JB guys jumping them in seniority. I wouldn't want it if I was them either.
