My Son is having trouble to find flights home on commercial flights. Is Space A a possibility? How would he look into it? What would be a good starting point for him to find out options if any? Thanks for any help! Another Coast Guard Dad !

If he is an eligible uniformed service member then, yes, it is possible. A good place to start is the FAQ www.spacea.net and also the location listings will provide the phone numbers he needs. More than likely he'll have to leave from Elmendorf or Eielson AFB. If he is stationed at some remote location then it may be more difficult. If he is active duty then he'll need to be on leave before he signs up.
