AA potentially closing accounts due to credit card churning/churn

How to know if you're locked: (as of 12/22/2019)

- Call in to aadvantage reservations (800-882-8880) If you locked, you'll be forwarded to customer service instead of getting to the automated reservations system
- If you want to stay on the line, ask CSR if your account is locked (you tried to make a reservation but it wouldn't let you). CSR will inform you there's a note on your account and that corporate security will contact you
- Try to make a reservation for a super cheap hotel through useaamiles.com. There are 1000 miles / night hotels in New Delhi, so at worst you'll risk 1K miles. If you're locked, you'll see "Unable to process points. Please call our customer service for assistance."

So far, nobody seems to have gotten unlocked and gotten access to their miles back. Accounts with upcoming travel seem to be the ones that are getting terminated at the highest rate.
