Changed airline on 1/30, purchased 2x $100 in separate transactions about an hour later (this worked fine earlier in the month for spouse w/ two different plats). Charges posted two days later with 1/30 charge date. Today 1/4 still no credit. Notes say taxes/fees/misc, which is different that spouse's charges earlier this month though I can't remember what those said.
All my attempts in the past have been successful and credited automatically within 2-3 days. I'm thinking this time it didn't, though I did nothing differently. I'll wait 8 weeks then inquire.
