Common problemAmerican Express
Amex large purchase declined
Spending power depends on your history
Cards with No Preset Spending Limit still have a flexible limit that changes with your purchase, payment and credit history. Amex may or may not approve spending over a credit card's limit based on your profile.
Fix it
How to fix it
Use the Check Spending Power tool in your online account or the Amex app before a big purchase.
For a Corporate Card, ask your company's Program Administrator about over-limit approvals.
