Pressure congress and continue raising awareness of the fact that your not flying on the airline your ticket states even though the paint job is the same and most of the planes even say ___ major airline on the registration.
If enough pressure is brought then maybe the flying will be brought in or cut the regionals loose and let them compete for the markets.
Whats disgusting is this should have never happened yet has been allowed to continue with the blessing of mainline pilot groups.
Very small chance anything will change as long as planes move.
