Another DP for Hilton Aspire:
4/10ish - Requested switch from AA to SW as a courtesy after AA started having issues. Granted due to long relationship (1981) w/ Amex. (Showed up immediately as Southwest.)
4/15 - Purchased $250 eGC
4/15 - Went pending for quite some time and was never emailed (48+ hours -- instead of the "up to 12"). So contacted Southwest on Twitter who said can take 72 hours but "pushed it through."
4/18 - eGC arrived. purchase posted.
4/19 - $250 credit issued & counter set to $0 available.
