Assuming you don't actually incur any fees, what is the consensus on best way to redeem the $200 Amex credit now that gift card no longer works. And don't say switch to xxx airlines... that's too easy

Stockpile 500 mile upgrades (which never clears)?
Buy day pass to AAdmiral Club for strangers you meet on the DFW air train?
Buy AA miles (which you cannot redeem because there is never award inventory when and where you want to go)?
Change your ticket just for fun (mess with AA revenue yield management for free)?
Buy drinks on board for the poor guy/gal stuck in the last row middle seat of 738 MAX?
