I have an American Express Platinum Card with the credit limit. I pay my bill every month in full. I had an unexpected expense pop up. But I am up to my limit on my American Express. This is closing date the 14th. When will I be able to charge again?
To answer your question: When will I be able to charge again?
After you pay your bill, then you'll be able to charge again. But as the comments have pointed out, if you call American Express, assuming you have had a good relationship with them, they should be able to approve a transaction if you let them know ahead of time (even if it's 10 minutes) and the amount.
