I don't know anything about it but Southwest's current advertisements bashes heavily on regionals. Never really thought about asking anyone there before but do the pilots have scope clause? Also why in the world would they push for 190s from a regional when they can operate 737s cheaper on their own? I was just looking at what it costs Southwest, and other airlines, to operate per pax they were almost half of the legacy guys. Don't see how that same pay would work in a 190.
