The Air Force launched a new website in March to simplify Space-Available flight registration, but five months later, some military travelers still don’t know it exists.
Air Mobility Command’s online tool — gatesea.mtmc.gov/amctravel — gives eligible travelers a centralized way to register for Space-A flights rather than emailing individual passenger terminals or submitting a paper AMC Form 140, Tech. Sgt. Dalton Williams, an AMC spokesman, said by email Tuesday.
Space-A travel allows eligible service members, Defense Department civilians, retirees and their dependents to fill unused seats aboard military flights after passengers traveling on official orders are accommodated.
The typically free flights operate from military passenger terminals around the world, including major hubs at Yokota Air Base, Japan; Osan Air Base, South Korea; Joint Base Pearl Harbor-Hickam, Hawaii; Ramstein Air Base, Germany; and installations across the continental United States.
Seats are never guaranteed. Availability depends on military missions, aircraft capacity and the traveler’s eligibility category, and passengers may be turned away at roll call.
AMC introduced the new website in March after a 60-day test at Ramstein and rolled it out simultaneously at its passenger terminals worldwide, Williams said.
However, the old registration methods remain available, and word of the new option has not reached everyone who might use it.
“It definitely feels like unless it’s someone who already frequently uses Space-A or someone who is actively planning to use it in the near future, the assumption is that nothing has changed,” Amy Beard said Thursday in a Facebook comment in the Yokosuka SOFA Members group.
The new system provides what Williams described as a “standardized digital interface” integrated with the Global Air Transportation System, or GATES.
GATES is a Defense Department logistic system used to track cargo and manifest passengers, including those traveling Space-A.
The website requires users to establish a Defense Self-Service, or DS Logon, account, or sign in using a Common Access Card, or CAC.
AMC encountered some problems after the website debuted, including form-validation glitches, delayed confirmation receipts and users unfamiliar with the new interface, Williams said.
Despite those issues, AMC says the new system is showing benefits over the old process, he said.
Initial data indicates more accurate registration timestamps, better visibility for travelers and terminal personnel and a significant reduction in administrative work at passenger terminals, Williams said.
“We continue to refine the tool based on user feedback and are committed to making Space-A travel more accessible and transparent for the military community,” he added.
