According to the other site and what I’ve heard separately, he doesn’t want to commute to terrible schedules anymore, doesn’t have a great feeling about the direction jetblue is headed having been one of two airlines that lost money last quarter (merging with the other), questions management’s ability to pull this off, and lives near a base at UAL in which he can upgrade in a year and can conceivably have about the same pay and a better QOL cutting out his commute than he’d have even at his seniority at jetblue for the next 15 years. Big pay cut first year, by his math he will catch up in 8-9 years, maybe sooner depending on contract cycles, then be above where he’d be at B6 after that for his last 5 years.
