Experience getting upgrades reimbursed?
I know the terms of the AMEX reimbursement benefit exclude upgrades, but what have people's experiences been getting those 500 mile upgrade coupons at $40 each reimbursed? Does it matter how many are purchased at a time?
I'm not sure what my chances are at getting a buy up offer at online check-in 24 hours before departure if I don't request an upgrade using coupons, but I'd be interested in people's experiences getting those reimbursed by AMEX as well.
