In other words, 10k is worthless, but just sit on it for a while and keep your eyes open for other promos. Watch for a particularly-juicy DL Amex teaser.
If it's been almost 3 years since last activity, goose the account with an iDine.
Ja_user could transfer the 10K into Mrs. Pinniped's account to = 30K for a ticket to Mexico or Caribbean, or 5K into each account for 2 free domestic tickets--if Pinniped pays the outrageously nasty
$125 transfer fee, which may be tolerable in this case.
