Nathan, I hope you're right! The airlines (esp. USA-based ones) are doing so well these days that they're going to have to go into a "lull" period - like the early '90s. Probably not so bad, but it would be good for travellers. Anyway, if there is going to be a change, it will have to be gradual. And besides, why would they want to change ff programs - they don't cost them that much - based on how few seats they seem to allocate to free travel!!
Thanks for the responses.
