Travelers cannot sleep overnight in the Portland International Jetport’s concourse, the secured area beyond the Transportation Security Administration checkpoint. The jetport’s terminal building is open 24 hours a day, but TSA screening, airline counters and concessions close after the final flight boards and generally reopen 90 minutes before the next morning’s scheduled departures. If you prefer a bed, the Hilton Garden Inn Portland Airport and Embassy Suites by Hilton Portland Maine are both within walking distance.
