MDT-PHL is a dash 8 so every seat is first class

but any idea why it would show PHL-LAX available and MDT-PHL-LAX not?
Thats why when looking at upgrade space, I look at each individual flight not the trip as a whole. If you are next in line for the upgrade on the PHX/LAX flight, youll get it as long as it remains available. It doesnt matter what MDT/LAX shows, just what PHL/LAX shows.
