Now here's a new idea from the Indonesian government following the AirAsia crash:
AirAsia QZ8501 Crash: Indonesia Vows New Curbs on Budget-Airline Fares
So how does an airline that charges $200 for a seat automatically become safer than one that offers seats for $20?? Well, at least much easier to implement than fixing the true underlying issues, such as government oversight of the industry, corruption, etc.
May be the assumption that $200 seat airlines can afford to service their aircraft better?
