PAUL LEWIS / PHOENIX Mesa Air says it can make 15 50-seat regional jets available to its US Airways Express operation, following the latter's scope clause deal with the Air Line Pilots Association (ALPA) allowing it to operate a further 70 regional jets. Mesa intends to continue introducing larger Bombardier CRJ700/900s with its other major partner America West despite ALPA's objections. "If they decide to put all 70 aircraft into [wholly owned] US Airways [regionals], it will take them years. We could probably make 15 aircraft available almost immediately, and from a logistical standpoint, there are benefits in getting it done sooner not later," says Mesa chief executive Jonathan Ornstein. Mesa operates 32 50-seat aircraft for US Airways Express, and is due to add four Embraer ERJ-145s.
