It is suggested that, before departure, pilots call facilities that do not publish FBO hours of operation to verify that someone will be there to stamp the passport.
For unattended airports, check the Locating a Stamp page for information on where the stamp may be located and/or call the airport contact number for additional information.
Pilots may wish to call airports, especially commercial service airports, to inquire about landing fees and other charges they may incur by flying into those airports.
Stamps may be obtained by participants who drive into airports as well as those who fly-in.
If in doubt about the safety of a flight due to weather, field conditions, runway length, etc., participants are urged to use sound judgment in deciding whether or not to make the flight.
