With the freedom of summer, families might be heading out for impromptu travel for some rest and relaxation. An option here at Joint Base Lewis-McChord is the ability of Space Availability (Space-A) travel. Here are some guidelines to know before hopping on an aircraft.

• First and foremost, register. Travelers have two options - in person at the passenger terminal on McChord Field or by fax/e-mail/postal mail.

• Determine if you are eligible. The full list of regulations can be found at www.amc.af.mil/amctravel/spaceatravelcategories.asp. Eligible travelers will fall into a category, which will then give them priority based on that category.

• Have flexible travel plans. From changes in the mission to broken aircraft, things can delay a flight - so keep a "Plan B" in mind. With possible mission cancellations, it might not be a bad idea to actually purchase a ticket with an airline, especially if you have a pressing deadline. Airlines usually have a refundable ticket option, but it comes with a price.

• Have your documents ready. Obviously, having your I.D. is a must. Some flights require passports and immunization records, so be sure to check with the passenger terminal ahead of time to see what's required.  

• Know the rules. Did you know that open-toe or open-heel shoes are not allowed? As for bags, passengers are allowed two bags per individual, limited to 70 pounds. You can have one carry-on bag, but it must be able to fit under any aircraft's seat.

• Have ground transportation contact numbers.

• Traveling to Japan or Korea? Air Mobility Command (AMC) flights have an additional set of rules and regulations. For starters, the flight departs from Seattle-Tacoma International Airport (SeaTac). Check-in time begins six hours prior to departure, and duty passengers must be in line no later than three hours prior to scheduled departure. Roll calls are conducted for Space-A travelers four hours prior to departure. Be advised that the flights out of SeaTac are not free.

• Know your lodging options. Be it on base or near an airport, always scout out your options while travelling. Again, with possible changes, you never know if you might have to unexpectedly stay the night at a departing station.

• Know where the local United Service Organizations (USOs) are located. Providing everything from a free phone call to a hot shower, the USO can come in handy if you find yourself in need of anything.

• Have a list of contacts readily available. Lodging, USO locations, taxis, destination/en route passenger terminals - if you can think it, have a number for it.
