Theoretically airline miles should hold value better than the dollar because they are tracking physical distance. I'm doubtful that has been the case.
I wonder if anyone has done a study on this.

I've heard airlines consistently rug their shitcoins. Huge inflation in airline miles. Someone talked about it on TFTC once.
I have stopped playing the credit card and miles game. Too fiat for me even though I could probably game it pretty well.
Air miles schemes change every few years, including the scheme rules, redemptions, earning etc.
Perhaps they were the inspiration for Ethereum.
Might depend on the airline, and the route, etc, but you can still get good deals using miles at price levels from 10+ years ago.
They can be debased at will. Airline miles are shitcoins. If you farm an airdrop the best move is to spend them ASAP because they always trend to 0.
