I'm no wiser as to your employer based on what you said, not that it matters; I was just curious as to what major airline would have guys close to command leave for RYR, or most other carriers for that matter.
Only you can decide what's best for you, but I would say this -
Leaving a decent job with decent seniority and everything that comes with it, and jumping ship (to one airline with a less than stellar reputation) based on not wanting to miss out on a time window, is a perilous idea. There are plenty of airlines which will consider your present experience. Add in the fact that RYR has so many intricacies and unknowns, and I really can't see why you're considering it, but that's just me.
