Frequently asked questions
Is customs clearance available at KPWM?
Yes, Portland International Jetport provides CBP inspection services onsite, along with a USDA compliance agreement for agricultural inspections. Crews do not need to divert to a nearby customs airport, since KPWM handles clearance directly. This makes it a practical port of entry for flights arriving from Canada or other international departure points. Coordination ahead of arrival with CBP remains standard practice regardless of onsite availability. The airport is towered, and airport attendance runs from 0600 to 2200 daily.
What runways does KPWM offer for arriving business jets?
Portland International Jetport has two paved asphalt runways available to arriving traffic. Runway 11/29 is the longer of the two at 7,200 feet, with a width of 150 feet. Runway 18/36 measures 6,100 feet long and is also 150 feet wide. Both runways carry high pavement classification numbers, reported as PCR values of 1468/F / C/X / T and 1439/F / C/X / T, indicating capacity for heavy aircraft. Noise abatement procedures apply for landings on runway 11 and departures on runway 29.
Is fuel available after hours at KPWM?
Portland International Jetport stocks both 100LL and Jet A fuel, and the field remains attended from 0600 to 2200 daily. Fuel service outside standard attendance hours requires prior arrangement, per airport remarks covering after-hours fuel requests. Dispatchers planning arrivals near or after the 2200 attendance cutoff should factor in this coordination step. The tower itself operates on its own schedule separate from general airport attendance. Crews should confirm fuel logistics directly with airport operations when planning late arrivals.
How does business aviation traffic vary by season at KPWM?
Business aviation traffic at Portland International Jetport, known by its ICAO code KPWM, is concentrated in the summer and early fall months. July recorded the highest monthly total in 2025 at 1,660 operations, followed by August at 1,322 and September at 1,070. Winter months show noticeably lower volumes, with January at 499 operations and February at 622. This seasonal pattern reflects the broader annual bizav total of 10,982 operations against 42,198 total annual operations, per FAA TFMSC data. Dispatchers should anticipate higher ramp and parking demand during the summer peak.
What ground movement procedures apply at KPWM terminal gates?
Portland International Jetport requires specific pushback routing from its terminal gates. Aircraft at gates 1 through 8 must push back onto taxiway A, while aircraft at gate 1A must push back onto taxiway C. Aircraft may not stop short of these taxiways during pushback from the respective gates. Pushback operators are advised to confirm clearance onto taxiway A or C before initiating the push. Ground control on frequency 121.9 handles this coordination at KPWM.
