Civil aviation authorities in some countries, such as the FAA in the US, keep and publish statistics of on-time performance for various airlines on various routes or at various airports. That information is useful to the consumer to form an informed choice as to which carrier to use or even which flight.
Award availability is a critical aspect of an FF scheme. Yet, it is shrouded in secrecy and we have nothing else than anecdotal evidence to compare FF schemes on this.
Shouldn't airlines be required to disclose and publish award availability statistics? There can, of course, be discussion as to which kind of statistics would be most useful to consumers. However, any kind of statistics would make a start at helping us comparing the value of different FF schemes.
