Regional Airports: Their Vital Role in Connecting Communities

When people think of airports, they tend to picture vast terminals, international departures boards, and hundreds of gates. But the reality of aviation infrastructure is far more granular. The United States alone has over 5,000 public-use airports, of which only about 500 have scheduled commercial airline service. The overwhelming majority are small regional and general aviation airports with one or two runways, a modest terminal building, and a handful of daily flights — or none at all. Yet these regional airports are the connective tissue of the aviation system, linking communities that would otherwise be isolated to the major hubs and, through them, to the world.

What Makes an Airport "Regional"?

There is no universal definition, but a regional airport typically handles fewer than 1 million passengers per year, serves primarily domestic routes, and connects to one or a few hub airports rather than offering nonstop service to a wide range of destinations. Some regional airports are remarkably small: the airport at Barra in Scotland uses a beach as its runway, with flight schedules determined by the tides. Others, like Baltimore-Washington (BWI) or Manchester in England, handle tens of millions of passengers and blur the line between regional and major airport.

The common thread is that regional airports exist primarily to connect their communities to the broader aviation network. A traveler in Dubuque, Iowa, or Inverness, Scotland, relies on their regional airport for access to connections at Chicago O'Hare (ORD) or London Heathrow (LHR) that would otherwise require hours of ground travel. This connectivity has economic, social, and medical significance that far exceeds the airport's modest traffic numbers.

Essential Air Service: Subsidized Connectivity

When the United States deregulated its airline industry in 1978, there was immediate concern that airlines would abandon unprofitable routes to small communities in favor of more lucrative hub-to-hub services. To prevent this, Congress created the Essential Air Service (EAS) program, which subsidizes airline service to small communities that would otherwise lose all scheduled air service. The program guarantees a minimum level of service — typically two daily round trips to a hub airport — using federal subsidies to cover the difference between operating costs and fare revenue.

As of 2024, the EAS program supports scheduled air service to approximately 170 communities across the continental United States, Alaska, Hawaii, and the US territories. Annual program costs exceed $350 million. The subsidy per passenger varies enormously: at some EAS airports, the federal subsidy per enplaned passenger exceeds $1,000 — meaning the government spends more to put each passenger on the plane than the fare itself. Critics argue the program is inefficient; defenders note that it provides a lifeline for communities where the nearest alternative airport may be 200 or more kilometers away.

The European equivalent is the Public Service Obligation (PSO) route system, under which EU member states can impose minimum service requirements on routes deemed essential for regional connectivity and subsidize operators to maintain them. France has the most extensive PSO network in Europe, subsidizing air service from Paris to dozens of smaller cities that might otherwise be served only by the TGV rail network or lose direct air connections entirely.

Economic Impact of Regional Airports

The economic impact of a regional airport extends well beyond the jobs directly created at the airport itself. Academic research consistently shows that airports with scheduled commercial service attract business investment, support tourism, and improve property values in their communities. A frequently cited FAA estimate is that every $1 of airport activity generates $3 to $4 in economic activity in the surrounding community.

In resort communities, the regional airport is often the single most important piece of economic infrastructure. Egilsstadir Airport in eastern Iceland connects a remote region to Reykjavik and, through it, to international tourism. The small airports serving ski resorts in Colorado, France, and Switzerland drive multi-billion-dollar winter tourism economies. Without air access, many of these communities would struggle to attract visitors from beyond driving distance.

Healthcare is another critical dimension. Patients in rural areas often need to travel to metropolitan hospitals for specialized medical care. Regional airports enable medical evacuation flights (medevac) and allow patients to fly to appointments that would otherwise require exhausting multi-hour drives. In Australia, where distances between communities can be enormous, the Royal Flying Doctor Service depends on the network of rural airstrips that serve as regional airports.

Operational Challenges

Regional airports face operational challenges that differ significantly from those of major hubs. Staffing is often the most pressing issue: a small airport may employ fewer than 50 people, yet must provide the same categories of service — security screening, firefighting, runway maintenance, air traffic services — as an airport ten times its size. Recruiting qualified staff to rural locations can be difficult, particularly for specialized roles like air traffic controllers and airport rescue firefighters.

Weather vulnerability is often more acute at regional airports, which typically have fewer runways (often just one), less sophisticated instrument approach systems, and less capacity to deploy snow removal or de-icing equipment. A single runway closure at a regional airport means complete cessation of operations, whereas a multi-runway hub can continue operating at reduced capacity. The gap in instrument approach capability has narrowed significantly with GPS-based approaches, which have brought precision instrument approach capability to hundreds of airports that previously had only non-precision or visual approaches.

Infrastructure maintenance is a constant concern. Runway surfaces deteriorate, terminal buildings age, and equipment wears out. Federal and state grant programs (like the FAA's Airport Improvement Program in the US) provide funding for capital projects, but the application process is competitive and funding is never guaranteed. Many regional airports depend on local municipal or county funding for operating expenses, creating political dynamics in which airport spending must be justified to taxpayers who may not use the airport themselves.

The Regional Airline Model

Regional airports are served primarily by regional airlines — carriers that operate smaller aircraft (typically 50 to 76 seats) on routes feeding traffic into major airline hubs. In the United States, regional airlines operate under "capacity purchase agreements" with major airlines: the regional carrier flies the aircraft, employs the crew, and performs the operation, but the flight is marketed, sold, and branded under the major airline's name. When you book a United flight from a small Midwestern city to O'Hare (ORD), the aircraft and crew are likely provided by a regional carrier like Republic Airways, SkyWest, or Envoy Air.

This model has faced significant strain in recent years. The pilot shortage — driven by pandemic-era early retirements, increased training requirements (the 1,500-hour rule in the US), and competition from major airlines hiring at unprecedented rates — has hit regional airlines disproportionately hard. Regional carriers pay lower salaries and offer less desirable schedules than major airlines, making it difficult to recruit and retain pilots. Several regional airlines have reduced service, returned aircraft to lessors, or entered bankruptcy, resulting in service cuts at dozens of small community airports.

The Future of Regional Aviation

Electric and hybrid-electric aircraft offer a potentially transformative future for regional aviation. The economics of short-haul routes with small aircraft are marginal with conventional jet or turboprop power. Electric propulsion promises significantly lower operating costs per seat-mile, potentially making routes profitable that are currently viable only with subsidy. Companies like Heart Aerospace (developing a 30-seat electric aircraft), Eviation (the Alice, a 9-seat electric commuter), and Tecnam (partnering with Rolls-Royce on a hybrid-electric design) are targeting precisely the regional aviation market.

Remote tower technology — using cameras, sensors, and data links to control airport traffic from a centralized remote location rather than an on-site control tower — could reduce staffing costs at regional airports. Sweden has been a pioneer, with LFV (the Swedish air navigation service provider) operating multiple remote towers from a single control center. Norway, Germany, and Australia have piloted or are planning similar programs.

The regional airport may lack the grandeur of an international mega-hub, but its importance to the communities it serves is often greater. For the resident of a small town who needs to reach a distant specialist hospital, the businessperson who needs to attend a meeting in the capital, or the tourist who has come to experience a region's natural beauty, the small airport with its modest terminal and single runway is as essential as any of the world's great aviation crossroads.
