So the quicker upgrade window lasts for the next 2-3(4?) years of hiring.

Another factor is the increase in additional G4 a/c. Line holding FO pays the same as 76 hrs of G2 CA rsv pay. The decision to give up 75% relative seniority, in a great gig, to upgrade to junior n/b domestic CA on reserve, makes G4 FO's pause. It's a constant topic of discussion since 1538 of 1541 G4 FO's are senior to the junior CA in the system.
