Airports in Benewah County, Idaho: Private, Municipal, Regional(All)

Airports Serving Benewah County, Idaho

Benewah County occupies the southern portion of Idaho's panhandle, home to roughly 9,500 residents in a landscape defined by dense forests, rolling Palouse prairie, and the southern reaches of Lake Coeur d'Alene. The county seat of St. Maries sits at the confluence of the St. Maries and St. Joe Rivers at 2,165 feet elevation, historically known as the "White Pine Capital of the World" for its once-dominant timber industry. Benewah County has no commercial airport, placing residents between two regional commercial options: Pullman-Moscow Regional Airport (PUW) approximately 70 miles to the south and Spokane International Airport (GEG) roughly 95 miles to the north. The county maintains a municipal airport for general aviation that supports the timber economy, recreational flying, and emergency services.

St. Maries Municipal Airport (S72) — Local General Aviation

St. Maries Municipal Airport serves as Benewah County's primary aviation facility, located adjacent to the St. Maries River on the west side of town. The airport features a 2,980-foot asphalt runway oriented 14/32 at an elevation of 2,175 feet. The relatively short runway limits operations to smaller general aviation aircraft—single-engine planes and very light twins comprise the bulk of traffic. The airport plays a critical role during wildfire season, when it supports Forest Service and Bureau of Land Management aerial operations in the surrounding Coeur d'Alene and St. Joe National Forests. Pilots approaching S72 should exercise caution regarding rising terrain to the east and north, river fog that can develop quickly in the St. Maries River valley during fall and spring, and bird activity associated with the nearby Heyburn State Park wetlands.

Spokane International Airport (GEG) — Primary Commercial Hub

Spokane International Airport provides Benewah County residents with the broadest range of commercial flight options. Located approximately 95 miles north via US-95 and I-90, GEG is reachable in about 1 hour and 45 minutes by car. The airport handles over 4 million passengers annually and is served by Alaska Airlines, Delta Air Lines, Southwest Airlines, United Airlines, American Airlines, Allegiant Air, Sun Country, and Frontier Airlines. Nonstop destinations from GEG include Seattle, Portland, Denver, Phoenix, Las Vegas, Los Angeles, Minneapolis, San Francisco, Salt Lake City, and Boise, among others. Alaska Airlines maintains the largest market share with extensive Pacific Northwest connectivity. The drive from St. Maries to Spokane follows US-95 north to I-90 west, a route that is generally well-maintained year-round though winter conditions on the US-95 corridor through the Benewah County hills can require snow tires or chains.

Pullman-Moscow Regional Airport (PUW) — Regional Alternative

Pullman-Moscow Regional Airport sits on the Washington-Idaho border approximately 70 miles south of St. Maries, serving the University of Idaho and Washington State University communities. Alaska Airlines operates daily service to Seattle (SEA) and Boise (BOI), providing convenient two-hop connectivity to the broader national network. The drive south from St. Maries follows US-95 through the rolling Palouse hills, taking roughly 1 hour and 20 minutes. PUW's smaller size means shorter security lines and an easier boarding process, though the limited route network restricts its usefulness to destinations reachable through Seattle or Boise connections. Fares from PUW tend to be higher than from Spokane due to reduced competition.

Coeur d'Alene Airport (COE) — General Aviation Gateway

Coeur d'Alene Airport, also known as Pappy Boyington Field, lies approximately 55 miles north of St. Maries via Highway 3. While COE has no scheduled commercial service, its 5,400-foot runway, fuel services, and rental car availability make it a useful landing point for private pilots visiting the northern portion of Benewah County or the greater Coeur d'Alene resort area. The airport is named for Medal of Honor recipient Colonel Gregory "Pappy" Boyington, the famed World War II Marine aviator who grew up in the region. Transient pilots landing at COE can rent vehicles for the scenic drive south into Benewah County along the eastern shore of Lake Coeur d'Alene.

Coeur d'Alene Reservation and Tribal Aviation Needs

The Coeur d'Alene Indian Reservation encompasses a significant portion of Benewah County, and the Coeur d'Alene Tribe is a major employer and economic driver in the region. Tribal government operations, healthcare facilities, and the tribe's gaming and hospitality enterprises generate business travel demand that contributes to regional aviation utilization. The tribe operates the Coeur d'Alene Casino Resort Hotel near Worley, which attracts visitors from across the Pacific Northwest and creates additional demand for airport access. Tribal health services coordinate with air ambulance providers for emergency medical evacuations, and tribal natural resources management programs utilize aerial surveys for fish habitat monitoring in Lake Coeur d'Alene and the St. Joe River system. The intersection of tribal sovereignty, federal land management, and state transportation planning creates a complex but collaborative framework for addressing Benewah County's aviation and transportation needs.

St. Joe River and Recreational Tourism Access

The St. Joe River, one of the highest navigable rivers in North America, flows through Benewah County and draws recreationists from across the Pacific Northwest for fishing, boating, and scenic enjoyment. The river's designation as a National Wild and Scenic River from its headwaters to the Benewah County community of Avery protects its outstanding natural character. Anglers pursuing native westslope cutthroat trout and steelhead travel from distant cities, most arriving through Spokane International Airport before driving south into the St. Joe drainage. The river corridor also attracts whitewater enthusiasts to the upper reaches and flatwater paddlers to the lower sections near St. Maries. This recreation tourism, while not generating massive passenger volumes, provides a steady economic contribution that benefits from reliable airline service at Spokane.

Benewah County's aviation picture reflects the broader pattern of Idaho's panhandle region: strong general aviation traditions rooted in forest management and rural connectivity, paired with dependence on Spokane's commercial airport for scheduled airline service. The county's position between two states' aviation infrastructure—Washington's Pullman-Moscow and Spokane airports to the south and north—provides more options than many similarly sized Idaho counties enjoy. Seasonal considerations matter: summer brings the best flying weather and road conditions, while winter demands preparation for snow-covered mountain roads on US-95 and Highway 3 when heading to commercial airports.

For outdoor recreation visitors—anglers, hunters, boaters on Lake Coeur d'Alene, and hikers in the St. Joe National Forest—reaching Benewah County by air requires planning but rewards the effort with access to some of the Pacific Northwest's most unspoiled landscapes. The Heyburn State Park, one of Idaho's oldest state parks, occupies the southern shore of Lake Coeur d'Alene within Benewah County and draws visitors from across the region. The St. Joe River, designated a National Wild and Scenic River, offers world-class cutthroat trout fishing accessible from both road and water. These natural attractions generate a modest but steady flow of out-of-state visitors who typically arrive through Spokane International Airport and drive south into Benewah County, contributing to the regional tourism economy that benefits from the panhandle's improving transportation connections.
