The questions about the arrival of the 'low cost airline model' are interesting. From having watched the arrival of the low cost long haul airlines (Braniff & People Express) in the days when the long haul market was far more restrictive, I can't say I ever understood why they failed. Seemingly excellent staff relations, happy and very flexible staff, good customer reputation, it seemed the future was in their hands, and they sadly failed. Maybe their time wasn't ready. Can we say for sure that it is the low cost short haul time now? They've had an excellent FEW years- will it last? I hope so- aviation is healthier with them here.
