Who you are contracting with, and why it matters
American Express Global Business Travel (Amex GBT) is a publicly listed company (NYSE: GBTG) that operates under a license of the American Express brand. It acquired Egencia from Expedia Group in 2021 and completed its acquisition of CWT in 2025. One corporate family therefore now sells three historically separate service models: the Amex GBT managed program, the Egencia technology-led offering, and the CWT book of business being integrated into both.
Two companies of the same size can therefore sit on very different fee structures under one parent. Before benchmarking any line, confirm from the signed agreement the contracting entity, the named fee schedule and its version date, and the booking platform it assumes.
- Egencia-led contract
- Typically priced around online self-service, with agent contact billed as an exception. Watch adoption assumptions and the cost of each human touch.
- Amex GBT managed contract
- Typically priced for complex, multi-country programs with account management, consulting options and a fuller offline service. Watch tiered offline bands and optional service bundles.
- Legacy CWT contract
- Signed before the acquisition and now subject to integration. Watch any clause that lets the provider move you to a different platform or schedule.
Amex GBT and Egencia fee lines to audit
Map every line on the last 12 months of invoices to one row of this table. Any invoice code you cannot map is itself an audit finding. Compare the ranges with our cross-vendor 2026 TMC fee benchmarks before deciding which rows to renegotiate.
| Fee line | Typical contracted range we see | What to verify in your contract | Red flag on the invoice |
|---|---|---|---|
| Online self-service transaction | $5–$12 | Whether air, hotel and car in one trip bill as one transaction or three | Per-segment billing on a single itinerary |
| Agent-assisted, domestic | $25–$45 | Which channels count as assisted: phone, chat, email, or only agent-completed bookings | Online bookings re-coded as offline after a chat message |
| Agent-assisted, complex international | $40–$65 | The segment or country count that moves a trip into the complex band | Simple round trips billed at the complex rate |
| Exchange, refund, void | $20–$45 per touch | Free void window and whether the exchange replaces or adds to a booking fee | Exchange fee plus a fresh booking fee on the same ticket |
| NDC servicing (agent-handled change) | $10–$25 extra | Whether it applies only to agent-handled NDC changes or to every NDC ticket | NDC fee on EDIFACT-issued tickets |
| After-hours and emergency calls | $15–$40 | Time-zone basis and duty-of-care exclusions | Surcharges on disruption calls during weather events |
| Hotel commission | 7%–10% of commissionable spend | Pass-through percentage and property-level reporting | No commission line in quarterly reviews |
| Unused ticket management | Included to $10 per reuse | Automatic reuse in the OBT versus manual agent reapplication | Reapplication billed as a full exchange |
| Reporting and account management | Included or fixed annual fee | Which reports are standard and whether raw booking data is included | Custom-report fees for the data your audit needs |
GDS incentives, overrides and channel-shift clauses
Large TMCs earn segment incentives from GDS operators and, on some routes, airline overrides. Those payments are lawful and normal, and some contracts use them to subsidize lower transaction fees. The audit question is what your contract says will happen when the volume that earns them moves. If your air program shifts toward NDC or direct airline connections to avoid the $12–$24 per-segment surcharges described in our NDC surcharge guide, GDS segment counts fall.
Read the agreement for any fee review, volume assumption or “commercial rebalancing” clause tied to segment volume, booking channel or supplier remuneration. A clause like that is not unusual, but it should be visible to you, it should require data and notice, and it should never operate retroactively. Ask in writing for the segment and channel assumptions behind your schedule, whether any minimum-segment commitment exists, and confirm that NDC bookings made in the OBT bill at the same online fee as EDIFACT bookings.
CWT migration clauses after the 2025 acquisition
If you signed with CWT before the acquisition closed, your agreement still governs until it expires or is amended, but integration usually means a platform, servicing location or fee schedule change at some point. Treat any migration letter as a contract event, not an operational notice. The three things to protect are price, service levels and data.
On price, confirm that the migrated schedule maps every legacy fee code to an equal or lower new code; mismatches usually appear in exchange, after-hours and complex-trip bands. On service, require the existing SLAs to carry over with the same measurement method. On data, require a complete export of profiles, unused ticket credits and loaded hotel rates before cut-over so your negotiated LRA rates do not disappear between systems. Our CWT merger playbook covers when to run a market test instead.
Hotel commission retention and offline NDC exchanges
Two lines are easy to miss on an Amex GBT or Egencia invoice because they do not appear as fees at all. The first is hotel commission. When a traveler books a non-negotiated property, the hotel may pay the agency 7%–10% of the room revenue. Unless the contract states a pass-through or fee offset, that revenue is the provider’s. On a program with $1.3M of hotel spend and 40% commissionable, an 85% pass-through is worth roughly $31,000–$44,000 a year.
The second is the cost of changing NDC tickets. Many NDC offers can be booked online but still need an agent to exchange or refund them. Add the exchange fee ($20–$45) and an NDC servicing fee ($10–$25) and a single change can cost $30–$70 in fees before any fare difference. Count your NDC exchanges for the last two quarters, multiply by the combined fee, and ask whether online NDC servicing is on the provider’s roadmap for your market.
Contract clauses to demand from Amex GBT or Egencia
Paste these into your redline. They are neutral, standard procurement language; the bracketed figures are the ones to negotiate.
Clause 3.4 · Channel-neutral pricing
Supplier shall not increase transaction fees, reduce credits or invoice any shortfall in GDS segment incentives, airline overrides or other supplier remuneration because Client directs bookings to NDC, direct-connect or other non-GDS channels. Any fee change linked to channel mix requires [90] days’ written notice, supporting segment data and Client’s written approval, and shall not apply retroactively.
Clause 5.2 · Platform and schedule migration
If Supplier migrates Client to a different booking platform, servicing entity or fee schedule, including any migration resulting from a merger or acquisition, the fees in Schedule B, the service levels in Schedule C and all loaded negotiated rates shall carry over unchanged for not less than [12] months after cut-over. Client may terminate without penalty on [60] days’ notice if any service level is missed in two consecutive months after migration.
Clause 7.1 · Hotel commission pass-through
Supplier shall remit to Client not less than [85]% of commissions, overrides and marketing payments received on Client’s hotel bookings, reported quarterly by property and booking reference, or credit the same against transaction fees in the following invoice period.
