1/2 - bought Delta tickets so I could use eGift cards from last year but still had charges of $173.30 and $33.30 after using the cards.
1/3 - bought a test $50 eGift card to make sure it was reimbursed
1/4 - I show airline fee reimbursement for the $173.30 ticket and $26.70 out of the other ticket
1/4 - I now have a non-reimbursed gift card.
Last year I also had this happen but in a smaller amount. I was reimbursed for a guest SkyClub entrance ($27) and $150 in eGift cards. The remaining $23 was reimbursed out of a ticket on Delta i purchased.
I will post an update if the airline fee reimbursement for an actual ticket changes before the statement closes.
