Keg,
It took you to bring me out of retirement, you are a lot smarter than that.
ASK's are an irrelevant number with the way yield management is undertaken these days. RPKs ASKs et al are no more useful than or accurate than the old days of saying 60 percent load factor is break even or anything greater than 80 percent and you are spilling.
With unbundling and add ons (read onboard sales) ASK's have little bearing on an airlines ability to generate revenue or at least profit.
IMHO
