Employee lot at GUM is staff-only, not public parking
The Employee Parking area at Antonio B. Won Pat International Airport (GUM) is a restricted long-term lot reserved for airport and airline staff, not for Main Terminal passengers. It sits on the airport grounds behind security-controlled access points and does not appear on the public parking map published by the Guam International Airport Authority.
This facility is set up for long-term use by employees with badges or issued permits, not for travelers leaving a car for a 3–14 day trip. Public information from guamairport.com only lists the main public parking adjacent to the Main Terminal, which charges hourly and daily rates, confirming that Employee Parking is outside the standard customer options.
There are no posted consumer rates, online booking links, or daily maximums for Employee Parking, unlike the public lot where fees increase after the first few hours. Access is controlled through staff credentials and internal airport procedures, so turning up at the gate with a boarding pass and asking to park here is almost guaranteed to fail.
No traveler reviews, FlyerTalk posts, or Reddit threads mention using the Employee Parking area at GUM as a workaround for public parking, which strongly implies enforcement is strict. Every public-facing guide instead points drivers to the main paid lot directly in front of the Main Terminal check-in area.
Tip: If you’re flying out of GUM, plan on using the main terminal parking or off-airport drop-off options; treat “Employee Parking” as off-limits unless you actually work at the airport and have the proper permit.
