How to Sign Up for Space-A Flights Online in 2026

Signing Up for Space-A: The Basics

Before you can fly Space-A, you need to register (sign up) at an AMC passenger terminal. The good news is that you don't have to be physically present — most terminals accept email sign-ups, and the process has become increasingly digital over the years.

Online and Email Sign-Up

Each AMC terminal accepts sign-ups via email. You'll need to send your sign-up request to the specific terminal(s) you want to fly from. Include your name, rank/status, ID number, number of dependents, desired destination(s), and contact information. Some terminals have online forms, while others use a standard email format.

What Happens After You Sign Up

Once registered, your sign-up date and time are recorded. This timestamp determines your position within your eligibility category. When a flight becomes available, the terminal calls roll based on category first (Cat I before Cat II, etc.) and then by sign-up date/time within each category.

Important Sign-Up Rules

• You can only be signed up at one terminal at a time.
• Sign-ups are valid for 60 days at CONUS terminals and 30 days at overseas terminals.
• You can update your destination preferences without losing your sign-up date.
• If you no-show for roll call, your sign-up may be moved to the bottom or removed.

Tips for the Sign-Up Process

• Sign up as early as possible — even weeks before you plan to travel.
• List multiple destinations to maximize your chances.
• Keep your contact information current so the terminal can reach you for roll call.
• Monitor flight schedules on Space-A Central to know when to show up for roll call.

Bottom Line

Signing up is simple — the hard part is the waiting. Get registered early, monitor schedules, and be ready to move when your terminal calls.
