The Camp Humphreys Commercial Travel Office assists Soldiers and civilians with booking their Official Travel, for the purpose of PCS, Emergency Leave, TDY, retirement, etc.
All official travel arrangements must be made through the Commercial Travel Office (CTO). Your assignment orders tell you when and where to fly. Travel can start as of Availability Date, from the Port of Debarkation (departure airport) to the Port of Embarkation (arrival airport).
When to Book Flights
Check your PCS orders for when and where to fly:
- Travel can start as of the Availability Date
- From Port of Debarkation (departure airport)
- To Port of Embarkation (arrival airport)
Paying for Flights
For the Government to pay for travel, flights must be booked via the CTO on a U.S. Flag Carrier, as required by the Fly America Act, ⚠ and orders must indicate either Individually Billed Account (IBA) or Centrally Billed Account (CBA).
Individually Billed Account (IBA)
With an IBA, your Sponsor (Service Member, DAC, Invited Contractor) will use a government travel credit card (GTCC) to pay for flights made at the CTO. Your Sponsor will then claim reimbursement by filling out a travel voucher during in-processing at the gaining installation.
Centrally Billed Account (CBA)
With a CBA, the CTO is responsible for paying for the airfare. The CTO charges the cost of airfare to a CBA and the CTO is reimbursed after submitting a claim.
NOTE: The CTO can book flights to and from alternate ports ONLY if the cost is less than your government travel entitlement.
Government Travel Entitlement
Use GSA City Pairs Search Tool ⚠ to find your government travel entitlement which is the YCA Fare (government negotiated, fully refundable, one-way fare) on a contracted U.S. Flag Carrier based on your departure or arrival ports on orders.
