It's a bad time to be at the bottom of anybody's seniority list at a new airline, which is where you'll be if you leave now. if they offer redundancy that would be a slightly different situation, but if do leave be very sure of what you're going to get when you get there. Grass generally looks greener until you get up close. I speak as one who was made redundant, and has found how hard it can be to resurrect a career from the right hand seat. Wait for the command plus 1000 hours of you possibly can!
