The Second-Busiest Secret
Hillsboro Airport Transfer Service One Town, Two Airports, One Gap.
Hillsboro is the rare suburb that owns Oregon's second-busiest airport and still drives 15 miles east to catch a flight. KHIO launches corporate jets, air ambulances, and flight-school traffic all day; it has never once boarded you for Denver. This guide takes the town's two-airport reality seriously: what the field on Cornell Road actually does, why the airline daydream keeps getting told no, the train station named after the wrong airport, and the ground craft that stitches both fields into one working travel system.

TL;DR
KHIO is Oregon's second-busiest airport, Port-owned, three runways, no airlines, and its FAA-approved master plan expects none for 20 years. Commercial flying means PDX: 83 scheduled minutes on the now-direct MAX Red Line for $2.80, or 45 to 52 free-flow driving minutes by our computed routing. We serve both fields, FBO curbs included, with flat quotes at $110 per hour in the S90.
The international-arrival sequence lives on the customs guide, standing corporate shuttle contracts on the contracts guide, and the westside dispatch craft on the dispatch board guide.
01The Field On Cornell
Oregon's Second-Busiest Airport
Has Never Sold You A Ticket.
The facts read like a riddle. By the Port of Portland's own description, Hillsboro Airport is the second-busiest in Oregon: established 1928, Port-owned since 1966, roughly 950 acres, three runways, an FAA control tower, and more than 25 on-field businesses spanning corporate and charter services, air ambulance transport, and flight schools. The FAA's pilot-facing page adds the punchline coordinates: 15 miles west of the larger Portland International. Busier than every Oregon field but one, and not a single boarding pass, because busy, in aviation, counts operations, and KHIO's operations are training circuits, corporate departures, and medevac launches, the whole industry except the part with a gate agent.
The recurring civic daydream
Every year the town's forums re-ask it, one thread titled "Will Hillsboro Airport Ever Serve Passenger Flights??" even naming its dream carriers. The longing is rational, the airport is right there, and the answer keeps arriving from the planning documents rather than the comment sections.
The 20-year no, in writing
The airport's FAA-approved master plan, finalized in May 2020, chose its future in one sentence: continue as a general aviation airport, with commercial service not expected over the next 20 years. The dream has an official expiration date, and it is decades out.
The one historical exception
Local aviation lore, recorded in the airport's Wikipedia history, holds that scheduled commuter service briefly existed in the late 1970s, small carriers hopping to Seattle's Boeing Field and the south coast. It did not last, which is itself the lesson: the market for boarding in Hillsboro has been tested, once, decades ago.
What two airports mean for a household
Practically: your commercial travel runs east on a 15-mile gap that belongs to no airline, no airport, and no schedule but yours, while the field in your own zip code occasionally matters enormously, the charter, the medical flight, the visiting jet. A town with two airports needs ground craft that knows both.
02The KHIO Side
Corporate Curbs, Customs Rights,
And A 6,600-Foot Main Runway.
The half of Hillsboro's aviation life most residents never see runs through two named front doors. Aero Air, on the field since 1956 and staffed around the clock, and Global Aviation, a full-service FBO with tens of thousands of square feet of heated hangar, are where KHIO's corporate traffic actually lands, refuels, and meets its ground transportation. The field's spec sheet explains the clientele: a 6,600-by-150-foot main runway that handles serious business jets, a tower attended 6 a.m. to 10 p.m., customs landing-rights status for international arrivals, and a landing fee for anything over 10,000 pounds. This is a working executive airport in every respect except the one the forums keep wishing for.
We stage at those FBO curbs on client instructions, timed to wheels-down: (503) 706-8662.
The FBO pickup, done properly
General aviation arrivals skip every terminal ritual, no carousel, no arrivals board, so the craft moves to coordination: the tail number's ETA, the FBO's visitor parking, the lounge-side greeting. A charter that lands at 2:40 wants wheels rolling by 2:50, and that margin is built the day before, not at the curb.
The two-airport day
The itinerary neither airport publishes: land at KHIO by charter, continue commercial from PDX, or the reverse. Fifteen unscheduled miles connect them, and a booked car that meets the jet and delivers you to the airline curb is the only instrument that makes the connection feel designed rather than improvised.
Medevac and the serious cases
Air ambulance transport is on the Port's own list of KHIO's businesses, and families orbiting a medical flight need ground logistics with zero improvisation in them: the right FBO, the right hour, a vehicle that can wait. It is quiet work, and it is exactly what a dispatch-run operation is built for.
The airshow weekend, annually
Once a year since 1988 the field goes public for the Oregon International Air Show's Hillsboro edition, and Cornell Road briefly meets festival traffic. For that weekend the two-airport town becomes a one-spectacle town, and transfers routed near KHIO get their buffers widened accordingly.
03The Rail Irony
The Station Named 'Hillsboro Airport'
Sends You To The Other One.
Transit handed the two-airport town a perfect irony: the MAX station at KHIO is named Hillsboro Airport/Fairgrounds, and the train that leaves it goes to PDX. Since the Red Line's westside extension opened, TriMet's own schedule runs it as a one-seat ride, every 15 minutes most of the day, $2.80, first train reaching PDX at 4:43 a.m. weekdays, and the timetable prices the trip in the only currency that matters: 83 scheduled minutes end to end. The forums noticed immediately, one local reporting the direct ride saves eight to ten minutes over the old transfer, and the cheapest option in town got meaningfully better, a fact an honest transfer guide states before making its own case.
Where the train genuinely wins
A solo traveler with a carry-on, near a Red Line station, with 83 minutes to spare and a midday flight: take the train, keep the $2.80 story. Frugality with that much time attached is a perfectly good travel decision, and we would rather say so here than pretend otherwise.
The 10:57 p.m. cliff
The last weekday train back to Hillsboro Airport/Fairgrounds leaves PDX at 10:57 p.m., which every delayed evening arrival should read as a deadline: land at 11:15 and the $2.80 option has gone home. The late-arrival gap is structural, and it is where pre-booked ground service stops being a luxury.
Downtown's asterisk
The one-seat ride starts at the Fairgrounds station; from downtown Hillsboro and Hatfield Government Center it is still Blue Line plus a transfer, the geometry one forum thread grumbled about by name. The further west you live, the more the train's arithmetic leans on patience.
The predawn availability question
The town's other recurring thread: will any rideshare actually accept a 4:30 a.m. Hillsboro request for a 6 a.m. flight? The first train reaches PDX at 4:43 a.m., often too late for the first departure bank, and the algorithmic cars are thinnest exactly then. Predawn is where booked-the-night-before earns its keep.
04The Ground Craft
The Transfer Math
For A Town With Two Fields.
The driving numbers, computed with the OSRM routing engine on OpenStreetMap data in July 2026 and labeled as the free-flow floor they are: KHIO's Cornell Road side to the PDX terminal runs 26.7 to 28.8 miles in 45 to 47 minutes via US-26 and I-205; downtown Hillsboro to PDX is 31.4 miles and about 52 minutes on the same corridor. Against the train's 83 scheduled minutes, the car buys back half an hour and adds what no timetable sells: a departure time that is yours, a cabin that holds a family and its luggage, and a driver whose westside routing adjusts live when the Sunset Highway does what the Sunset Highway does. The quote is flat, locked at booking, and identical at 4 a.m. and 4 p.m.
The corridor, known cold
Every Hillsboro-to-PDX run is one long corridor decision, US-26 over the hills, then the I-405/I-84 thread or the I-205 swing, and the right answer rotates with the hour. Driving it daily is the qualification; the computed table above is just the part of that knowledge that fits in print.
Rates, both airports
One rate card serves the whole two-airport system: Volvo S90 at $110 per hour, Escalade ESV at $135, Sprinter at $165, quoted flat per trip whether the destination is an airline curb at PDX or an FBO lounge on Cornell Road. FlightAware tracking and the 60-minute grace window ride along on every commercial leg.
Who books this route
The predawn tech traveler beating the availability gap, the family aimed at a 9 a.m. departure with four checked bags, the charter passenger connecting KHIO to PDX, the delayed arrival landing after the 10:57 train. Different problems, one solution shape: a vehicle that was always going to be there.
The standing westside file
Frequent flyers on this corridor keep a standing file through Hillsboro town car service: preferred pickup point, both airports on record, the FBO names spelled right. The two-airport town deserves a car service that never asks which airport twice.
Frequently Asked
Questions, Answered.
Can I fly out of Hillsboro airport?
Not on an airline: Hillsboro Airport is Oregon's second-busiest field, but it hosts corporate aviation, charters, air ambulances, and flight schools rather than scheduled passenger service. Private and charter aircraft use it constantly, which is exactly what it is designed for. Commercial travelers fly from PDX, about 15 miles east, and the transfer between the two is this guide's specialty.
What airlines fly out of Hillsboro Airport?
None today, and none are coming soon: the airport's FAA-approved master plan states plainly that commercial service is not expected over the next 20 years, keeping KHIO focused on general aviation. The wistful Reddit threads asking for an Alaska or Delta Connection counter get the same answer every year. A brief late-1970s commuter experiment is the exception history offers.
Is Hillsboro Airport public?
Yes, a public general-aviation airport owned and operated by the Port of Portland, which acquired the 1928-vintage field in 1966. It spans roughly 950 acres with three runways, an FAA control tower, and more than 25 on-field businesses. Public ownership does not mean passenger terminals; it means the field serves any properly certificated aircraft, from student trainers to corporate jets.
Is there a train from Hillsboro to PDX airport?
Yes, and since 2024 it is a one-seat ride: the MAX Red Line now runs directly from Hillsboro Airport/Fairgrounds station to Portland International, no transfer, every 15 minutes most of the day, $2.80. The scheduled end-to-end run is 83 minutes, with the last train back leaving PDX at 10:57 p.m. on weekdays, which is the number midnight arrivals should read twice.
How much is an Uber from Hillsboro to PDX?
Riders report fares that swing widely with demand, and the town's own forums document the deeper westside problem: predawn availability, with travelers unsure any car will accept a 4:30 a.m. Hillsboro request for a 6 a.m. flight. Our transfer answers both variables at once, a flat quote locked at booking and a vehicle assigned the night before, at $110 per hour in the Volvo S90.
