The Amex GBT US charge on your credit card statement is almost always a service fee from American Express Global Business Travel, a corporate travel management company that handles bookings for large employers. If your company books work trips through a centralized travel platform, the line item is the booking or management fee for that service, billed separately from the airfare or hotel itself. That separation is why the charge can look unfamiliar even when the rest of your travel expenses look normal.
Amex GBT Is Not American Express the Card Issuer
Despite the name, American Express Global Business Travel (often shortened to Amex GBT or GBT) is not the same company that issues American Express cards. American Express holds a minority stake in the travel company, which trades independently on the New York Stock Exchange under the ticker GBTG. GBT licenses the American Express name but operates as its own corporation with separate contracts, fee schedules, and customer service channels.1American Express Global Business Travel.

GBT’s business is managing travel logistics. Companies contract with GBT so employees can book flights, hotels, and rental cars through a single platform while staying within corporate travel policy. Its Neo1 platform handles trip booking, virtual payment cards, expense tracking, and budget dashboards.2Neo1. Neo1 – American Express GBT The practical takeaway: the charge came from a travel agency, not from American Express’s banking side.
Why the Fee Is Separate From Your Flight or Hotel
When you book a flight through your employer’s travel portal, the airline charges the ticket price and GBT charges separately for the logistical work of managing the reservation. Transaction fees for standard domestic bookings generally run between $5 and $50. Complex international itineraries and after-hours support can push the cost higher.
A few specific situations trigger the fee:
- Booking fees, applied each time you complete a reservation through the corporate portal.
- Change and cancellation fees, charged on top of whatever the airline or hotel charges to modify the reservation.
- After-hours support fees for calling GBT’s 24/7 line outside normal business hours.
- Offline booking fees, when an employee calls an agent instead of self-booking online.
Your employer’s contract with GBT determines which of these apply and at what amount, so the exact number on your statement varies by company.
How the Charge Reads on Your Statement
Card statements display the transaction under descriptors like “AMEX GBT US,” “AMEX GBT TRAVEL,” or “GBT TRAVEL SERV,” followed by a string of digits. Those digits often correspond to the 13-digit airline ticket number (the first three identify the airline, the remaining ten identify the specific ticket) or an internal reference code from GBT’s booking system.
The transaction date reflects when the booking was processed, not when you actually traveled. A June trip booked in March lands on your March statement. That timing gap is the most common reason the charge doesn’t ring a bell at first.
What If You Don’t Travel for Work?
If you don’t travel for work and your employer doesn’t use a corporate travel service, an Amex GBT charge on your personal card is a red flag. Before assuming fraud, check whether anyone with access to the account booked travel through a workplace portal, and whether a recent hotel or car rental might have run through a GBT-affiliated agency.
If none of that explains it, treat the charge as unauthorized. American Express cardholders can dispute a transaction by logging in, selecting the transaction, and using the dispute option.3American Express.

How to Verify a Legitimate Charge
If you do travel for work and the amount looks roughly plausible, match it against your booking records. Your employer’s travel portal keeps a history of reservations and associated fees. On the Neo1 platform, travel invoices for air and rail bookings become available about 48 hours after the reservation. Individual travelers find them under the expense receipts section; administrators can view invoices for the whole organization under the travel receipts menu.4AMEX GBT One Knowledge Base. Access Travel Invoices
Three data points speed the check:
- The six-character alphanumeric confirmation code (sometimes called a record locator or PNR), which ties the fee to a specific reservation.
- The confirmation email sent when the booking was completed, which shows the reservation and any fees.
- Your expense report, where airfare and agency service fees are broken out separately. A discrepancy usually means the fee posted separately from the ticket, not that something went wrong.
Disputing a Charge You Cannot Verify
Start with your company’s travel department or accounting office. They hold the master service agreement with GBT and can usually explain a charge within a day or two. Most questions get resolved here, because the internal team can see fee breakdowns that don’t appear on your statement.
If they can’t account for it, contact GBT customer service directly through the booking portal. Give them the reference number from your statement so support can trace the transaction to a specific booking.
When neither your employer nor GBT can explain the charge, you have the right to file a formal billing dispute under the Fair Credit Billing Act. Federal law requires you to send a written dispute notice to your card issuer within 60 days of the statement date. The notice needs your name, account number, the amount you believe is wrong, and why you think it’s an error. Your issuer must acknowledge the dispute within 30 days and resolve it within two complete billing cycles, with an outer limit of 90 days.5Office of the Law Revision Counsel. United States Code Title 15 – Section 1666 During the investigation, the issuer cannot try to collect the disputed amount or report it as delinquent.
Whether the Fee Is Refundable
Even when a flight or hotel is fully refundable, the GBT service fee usually is not. Corporate travel contracts treat transaction fees as payment for the booking service itself, which was performed the moment the reservation was processed. Canceling the underlying trip doesn’t undo that work. Changing or canceling a reservation may actually add another service fee on top of whatever the airline or hotel charges.
Your employer’s specific contract with GBT controls the details. Some agreements waive change fees for modifications made through the online portal but charge them for phone-based changes. Others include a set number of free changes per quarter. If you’re not sure what applies, your company’s travel coordinator can pull the terms from the service agreement. The refund policy on the underlying flight or hotel is separate and governed by that provider.
