My 2¢ (while we are still minting pennies)- at 32 & unattached I’d make the move. To paraphrase the old investment axiom, “Time [at your retirement airline] is more important than timing”. The last decade (COVID aside) has conditioned many of us to think boom times are the norm. (They aren’t.) Economic uncertainty is usually dangling out there, & signing on to the bottom of a seniority list is usually scary. Luckily your life circumstances seem to provide you decent flexibility in a worst case scenario.
