Landing essentials
Whether you can land, whether you can refuel, and how customs works here.
Overview
Houlton International (KHUL) sits near the US-Canada border in northern Maine, serving business aviation traffic with two paved runways and onsite customs processing. The airport reports FAA TFMSC crossing traffic rather than total field activity, reflecting its role as a border-adjacent point of entry. Attendance hours shift seasonally, with longer coverage from May through October and a reduced schedule the rest of the year.

Frequently asked questions
Does KHUL have customs available onsite?
Yes, Houlton International offers onsite CBP inspection services along with a USDA compliance agreement. A USDA recatering facility is also available at the field. This combination supports international arrivals without requiring a diversion to another port of entry. Operators should still confirm current procedures directly with CBP given the airport's unattended weekend schedule.
What are the runway options at Houlton International?
Houlton International offers two paved asphalt runways: 05/23 at 5,015 feet by 100 feet, and 01/19 at 2,700 feet by 60 feet. The longer runway, 05/23, is lit dusk to dawn with REIL on both ends and PAPI on runway 05, activated via CTAF. This gives operators a substantial primary strip alongside a shorter crosswind option.
When is Houlton International attended?
KHUL follows a seasonal schedule: Monday through Friday 0600-1630 from May through October, and 0700-1530 from November through April. The airport is unattended on weekends year-round. After-hours access to the terminal building is available on frequency 122.8. Operators flying into Houlton International outside these windows should plan for self-service conditions.
Is fuel available at Houlton International outside staffed hours?
100LL is available 24 hours at Houlton International with a major credit card, while Jet A fuel requires after-hours arrangement rather than standing self-serve access. Both grades, along with A+ and A1+, are listed among the field's fuel types. Operators planning Jet A uplift outside attended hours should factor this distinction into their fuel planning at KHUL.
