A 5 month notice of schedule change is likely to occur on almost any airline. AR's biggest problem is that one is likely to have an unanticipated day-of-travel schedule change, which might have you wandering around an airport aimlessly for hours, or be stranded in a city without a hotel reservation, or missing your reservation in the next city, and so on and so on. This is what a subsidy of approximately US$2M a day buys. I sense that if they threw another $1M a day at the company, it would even be worse.
