Without slinging any mud, I would say that giving up what I presume to be a chunk of seniority in a major airline, on a far better contract (again, assumption on my part) to get a 737 command two years earlier (if I've understood you correctly) at RYR would be gutsy, at best.
Throw in all the other 'intricacies' of RYR regarding bases etc., and that may pad out my point.
If you don't mind me asking, which major carrier are you working for?
Good luck!
