Booked an AA OW flight and went back in a day later to change the "regular" seat to a MCE. Transaction for the $63.57 for the MCE seat posted on 1/22 and the CREDIT of $63.57 posted on 1/25. Still need to use $36.43 of the Amex Gold credit but overall still pretty happy with them allowing MCE as a credit option. Definitely a little more effort than just getting a gift card last year but as long as MCE stays an option I am ok with it.
