Checked my American Express online account today. Interesting reimbursement experience. I had previously used $126.49 of my $200 credit earlier in the year, leaving me with $73.51 reimbursement balance on my Amex Platinum for the rest of the year.
April 30: Purchased a ticket that was priced at a little over $180. After applying all of my existing Alaska Air discount codes, the total came to $100.40. I fully expected to NOT have any of this reimbursed by Amex. By the morning of May 2, the full $100.40 posted as normal.
May 2: Purchased a ticket in the amount of $53.33. I DID expect to have this charge reimbursed, which would leave me with a reimbursement balance of $20.18 for the rest of the year.
May 4: Received an Amex Airline Fee Reimbursement in the amount of $73.51. I have now used my full $200 for the year. This was unexpected, but it is appreciated.
