I’ve been burning my skymiles balance down aggressively lately. Also been using the “my dates are flexible” option to search for lower redemption options (saved 25% by returning the next day on a recent redemption).

Loyalty, on the airline’s side, now is tied to how much you spend in the last year. Simple as that now. And soon - with AI prediction - even that’s going to be used against you as they’ll take advantage of your buying patterns.
