Does anybody with an amex card know what happens if/when the card is overpaid? Or if it is overpaid and it is used to purchase something, is the overpaid balance applied to the available balance immediately or does this take some time?
For context: I recently signed up for an amex airpoints card to make use of the travel insurance. For the insurance to be valid the flights must be paid in full with the card. When I signed up I was assigned a limit by default. The flights I need to by are more than the limit, making it very tricky (or near impossible) to access the insurance.
Any suggestions on ways to make this work much appreciated, I feel like I've tried most options, but am reluctant to pay for separate insurance if I can help it…
Whilst I don't have an Amex any more, from what I recall, if you paid, say, $10,000 onto the account (and assuming no other transactions around the same time), it just means that whatever credit you had available the day before, you now have that plus $10,000 available.
If your credit limit (overall) is $50,000 and you had nothing owing, then the $10,000 payment would put you $10,000 in credit, and you would be able to spend $60,000 on one (or multiple) transactions at that point.
I can't recall how long it took to show up, but I'd be surprised if it was more than a day.
If you want to be sure, call them and ask?
