Plan your trip, be flexible, be patient. As a rule of thumb, military ports offer more travel opportunities than commercial gateways (i.e., travel chances are better to Europe from Dover AFB, DE than Philadelphia IAP, PA). Rhein-Main AB, Germany is closed.
If possible, travel at off-peak Space A travel periods (i.e., peak periods are the summer months after school is dismissed and Christmas holiday season). Historically, Feb-Mar and Oct-Nov are low travel periods.
Be as flexible as possible in choosing a destination. If you want to get to Ramstein AB, Germany, consider a flight into Rhein-Main, Germany, or even RAF Mildenhall, United Kingdom, as an alternative. At Mildenhall, try for another flight bound for Germany.
When traveling Space A with young children, prepare for possible delays along the way where baby supplies may not be readily available. A good supply of games and books is also recommended. Be aware that a baby's ears, like an adults, are sensitive to altitude pressure changes.
Space A is just that--space that is available after all mission requirements are fulfilled. Military aircraft are subject at all times, first and foremost, to DoD mission response.
