Chasing airline status (esp. in the US3 programs) has been a mostly sucker move for much of the past decade, and definitely during the 2020s. Delta's move confirms SkyMiles elite status cards are like the VIP cards doled out by casinos, a badge of idiocy versus some kind of positive outcome.
Smart travelers have spent the 2020s focused on personal income growth and/or increasing flexibility in travel spend. FFP changes don't really mean too much to us. 🤷♂️
