CSeries slots are not hard to attain, currently Bombardier hasn't seen the or seeders they were hopping for this aircraft coupled with the Q400 having a small list and the CRJ, Bombardier's production lines are close to a stand still. The CRJ line is only producing 5ish aircraft a month. Bombardier could easily find early slots for AMR and if the CSeries debuets as planed (2013) RAB will possibly have to either defer or sell slots since they don't have anyone to fly them for exept the "theory" the rev came up with about flying them for One World, star or sky team!!
