Thanks for the response. Maybe I don't understand mileage accrual. On any OW flight, will I be able to put my AA number and accrue at the AA Plat rate?

After three years it will either be back to the states or Germany (FRA).

Yeah, it sucks about no soft-landing. That's how they keep us coming back!

As for expiry, the miles will be gone this summer anyway so the only holding power to AA is the current Plat.
