How early should I arrive at Centennial Airport?

Centennial Airport (APA) in Denver primarily serves general aviation, corporate, and charter operations rather than large commercial airlines, so passenger facilities differ from a typical commercial terminal layout. The airport is a busy reliever for Denver International Airport and hosts flight schools, private jets and several fixed-base operators; popular destinations reflect business and recreational travel throughout the Rocky Mountain region and nationwide charter routes. Travelers can check the airport’s online flight board (online flight board) for up-to-date arrivals (arrivals) and departures (departures) information, ground transportation options, and FBO services before arriving.
