Amex airline incidental fee credits usually post within a few days after the charge posts , though it can sometimes take up to about a week or more. Public reports and guides describe typical timing as around 2–3 business days after the transaction posts, and one recent guide notes reimbursements often appear about 10 days from posting rather than from the purchase date.

What to expect

  • The credit is tied to the posted transaction , not the purchase date.
  • Many cardholders see it in 2–3 business days.
  • If it hasn’t shown up after about a week , that’s still not unusual, especially around weekends or holidays.

Important detail

Amex airline fee credits are generally calendar-year benefits and must be used on your selected airline. They’re meant for incidental charges like baggage or similar fees, not regular airfare.

Simple example

If a fee posts on Tuesday, the reimbursement may show up by Thursday or Friday, but sometimes not until the following week.

When to worry

If the charge clearly qualifies but the credit still hasn’t appeared after roughly 10–14 days , it may be worth checking the transaction coding or contacting Amex.
