Say you decide you finally dislike (for various reasons you may have of your own) a certain Airline now.

BUT you have a few thou--or maybe a lot of miles with their FF program.

I have a few thoughts of my own on this one, but am curious as to what people would do here? Remember, they ALL have done some nasty things to us... or will, and they switch their OWN partners and loyalties a lot like lovers get deceived in a soap opera.

An example is that you have 15,000+/- miles with the airline but that's about what you have with all the others too. Should you let 'em eventually go away by expiry or use em somehow and be done? How and what to do?

Thoughts (based on this OR your own experiences)?

If speed is not your thing, distance may as well be. Enjoy and embrace it all!
