How are we defining mainline?
My definition of mainline has always been narrow body or wide body aircraft operated by the "named" airline, vs turbo prop and regional jet aircraft operated by regional carriers in the name of the main airline.
Even though in this case some of the CRJ aircraft probably need more runway to take off than a 737-700. Small wings, small engines.
The planes that are borderline are the short small tube (2+3) narrow bodies like the 717 and the short DC-9s.
