I would be strongly opposed to eliminating the title Regional from these forums. The forum structure is designed to be user friendly and easy to navigate (we hope), not to make a political statement.
Newcomers would be very confused.
I don't really have an issue with adding the word "Contract"..ie "Regional/Contract Airlines" but this could cause confusion too..we would get people interested in contract flying jobs for foreign airlines.
The industry term is "Regional"...how it evolved is not too important but we are not going to be able change it unilaterally. You guys think RAA is going to change their name to "CAA"?
"Fee-For-Departure" airlines might be a little clearer, but even that term is becoming less relevant as contract terms evolve into more risk-sharing.
