Passengers will continue to endorse and support AirAsia's low cost model because they will continue to buy tickets. They are the only ones who can ultimately 'regulate' the LCCs by paying proper fares to proper airlines, but they won't. It costs more than USD30 per seat to fly an A320 from SUB - SIN. So if you get a ticket for that you should understand that you get what you pay for and accept the consequences.
