If the FAA is increasing the requirements for new pilots at the regionals, which is causing a shortage of candidates, which is (as it should in a free market economy) pushing up the pay rates for new rj pilots, then does it not reach a point where the cost advantage/raison d'etre of regional jets goes away? For instance we have recently started (could be, resumed, but that would be before my time...9/2000) mainline flights to Lubbock and Corpus Christi. Is this cost increase in rj flying involved?
