Depends on the individual contracts and the extent to which major pilot unions can be bribed into scope relief. Prior to COVID, UA pilots were holding the line pretty well. But other things play into the equation as well. The lack of new 50 seaters was being countered by airlines derating the larger RJs into 2 class less than 70 seaters, but will that be economically feasible if business flying doesn’t promptly return? Right now the ULCCs and SWA seem to be leading the comeback, with both F9 and NK already hiring for the new aircraft they have coming in, and SWA has a rumored order of dozens of new Max’s. The legacies probably cannot survive a CASM fight with aircraft that started out as 80 seaters now de rated to 60 seaters against MAX 7s and A319 NEOs.
