DAF Form 140: Space-A Travel Request (Download PDF) – Space-A travel (Space Available) lets eligible U.S. military members, retirees, veterans, and their families fly on Department of Defense (DoD) aircraft when seats remain after mission-essential passengers. It offers a budget-friendly way to travel domestically or internationally with minimal or no airfare—often just head taxes or inspection fees.
The key document for signing up is the DAF Form 140, officially titled Space-Available Travel Request. (It is frequently referred to as AMC Form 140 on the Air Mobility Command site.) This form registers you for Space-A flights at AMC passenger terminals.
What Is DAF Form 140 (AMC Form 140)?
DAF Form 140 is the official request form used to register for Space-A travel on military aircraft managed by Air Mobility Command (AMC). It collects essential traveler information so passenger terminals can add you to the Space-A register.

Who Can Use Space-A Travel? Eligibility Overview
Eligibility follows DoDI 4515.13 (Air Transportation Eligibility). Travelers are placed into one of six priority categories (Cat I highest, Cat VI lowest). Priority within a category is based on sign-up date and time.
Main categories include:
- Category I: Emergency leave unfunded travel (highest priority).
- Category II: Accompanied Environmental and Morale Leave (EML).
- Category III: Ordinary leave (active duty), house-hunting permissive TDY, Medal of Honor holders, etc.
- Category IV: Unaccompanied EML.
- Category V: Certain permissive TDY, students, dependents, post-deployment respite, etc.
- Category VI (lowest): Retirees (with blue ID card) and their accompanied dependents, certain Reservists/Guard, 100% permanently disabled veterans (with VA documentation), and surviving spouses of service members who died in duty status.
Key rules:
- Active duty members must be in valid leave or pass status when signing up and while traveling.
- Retirees and Category VI travelers can generally fly CONUS-to-CONUS, CONUS-to-OCONUS, and OCONUS-to-CONUS (subject to restrictions at specific locations).
- Dependents usually need to travel with their sponsor (exceptions exist for certain EML or deployment-related travel).
- All travelers need proper ID (CAC, dependent ID, retiree ID, etc.), passports for international flights, visas if required, and any country clearances per the Foreign Clearance Guide.
Geographic restrictions apply—some categories have limits on where they can travel (e.g., certain OCONUS segments). Check the full details in DoDI 4515.13 and with the specific passenger terminal.

Step-by-Step Space-A Travel Process
- Confirm eligibility and gather documents.

Tips for Success with Space-A Travel
- Flexibility wins — Category VI (retirees, disabled vets) travelers often succeed by having multiple destination options and patience.
- Sign up early within your category for better position on the register.
- Check multiple terminals—popular routes from hubs like Travis AFB, Ramstein AB, or Joint Base McGuire-Dix-Lakehurst fill quickly.
- Have a backup commercial travel plan.
- For families: Ensure all dependents have proper ID cards (children under 14 may need birth certificates in some cases).
- Stay informed: Policies on EML, deployment-related travel, or disabled veteran eligibility can have nuances.
Current as of 2026: Always verify the latest rules on the official AMC website, as flight availability, fees, and procedures can change.
