At most bases, there are four ways to sign up for Space A travel:

  • A completed AMC Form 140
  • On-line registration (e-mail)
  • Fax
  • In person

If you are on active duty, you MUST be on leave or pass status at the time you register for Space A travel. You must also be in such status while you're waiting to be accepted.

The following information is generally required for a successful sign up:

  • Name
  • Rank/Grade
  • Social Security Number
  • Branch of service
  • Start and stop dates of leave (for active duty only)
  • Category (I - VI)
  • Number of passengers traveling with you
  • Destination (up to five may be chosen)
  • Name and Social Security Numbers of any dependents who will be traveling with you

Sponsors who register in person for family members traveling with them should present all required documents:

  • Identification cards (DD Form 2, Armed Forces Identification Card)
  • Passports
  • Immunization records
  • Visas when required by the DoD Foreign Clearance Guide

Travel documents must be presented when selected for travel. Travelers may select up to five countries. We recommend the "all" choice for the 5th destination so that the traveler may take advantage of unscheduled unique travel opportunities.

After you register, an email will be sent to the selected departure location and to your e-mail address. You will compete for seats within a travel category based on the date and time of your registration. This determines your selection on all flights to your selected destination. When you get to your final destination, be sure to sign-up immediately for your return travel. This will give you the "best" date and time for competing for seats on those flights.

You can sign up at multiple gateways where you think you will originate your travel. Once registered, your names remain on the Space A flights register for whichever occurs first:

  • 60 days, or
  • the duration of the travel orders/leave authorization, or
  • until you are selected for travel

Active duty military may travel on a pass in the CONUS and selected overseas areas but may only remain on the Space Available register for 72 hours.

Passengers authorized (in writing) for a special 96-hour pass will remain on the list for 96 hours. If a passenger subsequently presents a leave order valid for the (pass) day of sign up, during or after the 72-hour period, they must sign up again with a new date and time.

Passengers who possess expired leave authorizations will not be able to register unless a leave extension has been approved. A verbal confirmation will be acceptable. Passengers already on the space available register requesting a leave extension are required to notify passenger service personnel prior to their leave expiration date. Your name will remain on the space available register as long as you are pursuing a leave extension. Passengers will not be selected or moved until an extension has been approved.

There are four types of sign-up:

  • Country - Under this program, you may sign up for five different countries rather than five different destinations. You are also eligible for the "ALL" sign-up which makes you eligible for all other destinations served. This gives you a greater selection of destinations from which to choose.
  • Remote - Remote sign-up allows passengers to enter the backlog by telefaxing copies of proper service documentation along with desired country destinations and family members' first names to the aerial port of departure. The telefax data header will establish date/time of sign-up; therefore, active duty personnel must ensure the telefax is sent no earlier than the effective date of leave. AMC terminals are not responsible for faxes not received. Mail entries will also be permitted. Some of our AMC terminals now accept e-mail sign-up (see paragraph 11 for those terminals so equipped). The original date and time of sign-up shall be documented and stay with the passenger until his or her destination is reached. On reaching destination, the passenger may again sign-up for space available travel to return to home station. NOTE: If applicable, a statement that all required border clearance documents are current, is required.
  • Self - Self sign-up is a program that allows passengers to sign-up at a terminal without waiting in line. Most locations now provide self sign-up counters with easy to follow instructions for registration. Active duty personnel must ensure sign-up takes place no earlier than the effective date of leave. If your travel will take you to a foreign country, ensure border clearance documentation is up to date. If you are unsure, verify it with a passenger service representative on duty.
  • All - Eligible to sign up for all other destinations served and gives the traveler a greater selection of destinations from which to choose.
