Prior to COVID regional block ran 85-90% of mainline block. UAX was scoped out on the big rj’s, and the company really didn’t want that many 50 seaters, but scope left them the choice of more mainline, or more 50 seaters. In the last 4-5 months express has been flying way over 120% because of the history of being under 100%. With mainline greatly reduced, express will have to stay below mainline NB block until the LOA terminates. United will maximize the use of the bigger rj’s, and this could alter the timeline for the reduction of the 50 seaters. Until United is running a full schedule, UAX will be given less flying. If they have to make a decision to reduce 70 seat hours (all 76 seat jets have to be converted to 70 while mainline is on reduced work) or 50 seat flying, my money says that it is the 50 seat fleet that takes the biggest hit. If this LOA is short lived, UAX could go back to what it was, if this drags on, the company will likely permanently alter the fleet mix and retire the 756 and all but a few 50 seaters. Grab a beer and pop some popcorn, it should be an interesting show. The carnage isn’t over yet.
