Well if the wife wants Denver you’re probably going to Denver.
Based on the December seniority list at GoJet(G7) the junior FOs in DEN are 8/17, 6/17, 6/17, 4/17 so yes in theory with 6 months “banked” seniority plus training time you should be able to hold a DEN base after IOE (initial operating experience)
If living in Denver and not commuting are your highest priorities then GoJet may be a good fit for you.
If you want to PM I’ll give you my number and we can discuss the other pros and cons.
