Bye-bye American Airlines AAdvantage
I think the last time I flew American Airlines was due to great redemptions to South America about 20 years ago. Do I recall flying United? Yes. Delta? Yes.
Well, it kind of hurts a little to give up my progress towards Million Miler, but then again Million Miler only gets you OneWorld Ruby status; priority check-in and no lounge. It's not a great benefit considering I can easily get priority check-in via a credit card.

Priority check-in used to be great about 20 years ago. With good airlines these days the check-in is either not that long, or with great airports the check-in is largely automated now. The time savings and what I value priority check-in is at next to nothing now. It's perhaps 10 mins difference or less. Many airports also offer in-town check-in, which also diminishes the value of priority check-in given it's so quick and easy. As there's no lounge access even with Million Miler I'm happy to let this account go.
Does it really take that much effort for an airline to support Apple/Google logins? I'm tired of having 300+ logins, so I've decided to abandon all services that don't support an Apple/Google login. I don't want to deal with 300+ credentials even if I do have a password manager.
