As a former EAL A-scaler, the senior mainline guys, since 1983, have been subsidized by first the B-scale, then the low fuel prices and B-scales, finally, this last decade by the regional guys. The RJ guys are B-scalers in disguise.
Will the mainlines "recapture" the scope clauses by allowing a C-scale to fly planes under 130 seats? The 50-seaters are doomed by economics, followed closely by the 70-seaters; so there must be a C-scale for the C-series/EMB-195 class planes soon to arrive. DL certainly wants them to replace the old DC-9s, uneconomic 50-seaters, just at RJ pay rates. They don't care what company flies them, just as long as the compensation is low enough.
Does ALPO cave on the pay or the scope? Coming to a LEC meeting near you.
