The other thing: FF programs are like casinos; it's entirely up to the airline/casino how much value to return to the customer. I don't think Harrah's is going to shut down their casino just because someone was able to count cards and come away with a few thousand in winnings. They just make it tougher to count cards and change the rules (blackjack payouts going from 3/2 to 6/5).
They have become huge profit centers...many airlines have spun them out as separate entities. They are not going away...changing yes....
