U.S. regional airlines might not boast the fame of their mainline counterparts, but they play an incredibly vital role in domestic travel. As we dive deeper into this world, one thing becomes clear: without regional airlines, American travel would come to a standstill. These carriers, often operating under well-known brands like Delta Connection, American Eagle, and United Express, serve as the glue that binds the far-flung corners of America with its bustling hubs.
It’s easy to overlook how much they contribute. Yet, every time you fly from a smaller airport like Fayetteville (XNA) or Jacksonville (TLH), you’re benefitting from a regional airline’s network. These airlines don’t just serve tiny airports — they carry millions of passengers annually and provide essential connections that are key to the U.S. air travel system.

Regional Airlines: Connecting Big Cities and Small Towns

Imagine flying from Chicago O’Hare (ORD) to a tiny regional hub with just a handful of gates. What seems like a small city may just be the key to your connection to another major city. Regional airlines make this possible. They are the silent engines of U.S. domestic travel, carrying passengers from bustling hubs like Atlanta (ATL), Dallas/Fort Worth (DFW), and Chicago (ORD) to small regional towns and back.
For example, SkyWest Airlines alone serves over 258 destinations, connecting smaller cities to larger hubs. Without these airlines, cities like Bentonville (XNA) and Fort Smith (FSM) might remain disconnected from the rest of the world. What’s more, these airlines ensure that there are always affordable, convenient options for U.S. travelers no matter where they are.

U.S. Regional Airlines: Major Players in the Industry

When most people think of air travel, they think of American Airlines, Delta, or United. But what many don’t know is that much of their flights are actually operated by smaller regional airlines under capacity purchase agreements. These airlines are often tied to larger brands, such as American Eagle, which flies on behalf of American Airlines, and Delta Connection, which is operated by Endeavor Air and others.
As a result, regional airlines have built powerful networks that link major airports with smaller communities. In fact, American Eagle, under its brand, operates flights to 242 destinations and is one of the largest regional carriers in the country. Meanwhile, Delta Connection, with its subsidiary Endeavor Air, connects cities like Minneapolis (MSP), Detroit (DTW), and Salt Lake City (SLC) to the farthest reaches of the U.S.
It’s clear: these smaller airlines are critical to the U.S. domestic travel system. They keep cities connected, ensure the economy keeps moving, and most importantly, help ensure that Americans can easily fly from coast to coast.

SkyWest and the Empire of Domestic Flights

When it comes to U.S. regional airlines, SkyWest stands as a colossus in the industry. This regional airline operates flights for not one, not two, but four of America’s largest airlines, including Delta, United, American Airlines, and Alaska Airlines. They serve over 258 cities across the U.S. This means SkyWest Airlines flies to every corner of America, from major cities like New York (JFK) and Los Angeles (LAX) to regional gems like Jacksonville (JAX) and Montrose (MTJ).
Without SkyWest, thousands of American travelers would have fewer options to get from point A to point B, leaving them stranded in small towns with limited access to major cities. SkyWest’s contribution to U.S. domestic connectivity is nothing short of transformational. It is an absolute game-changer in the world of domestic aviation.

U.S. Regional Airlines: Vital Links Between Big and Small Cities

Regional airlines serve a critical role in connecting smaller cities to major metropolitan hubs. Let’s take a closer look at how these routes create a vibrant, interconnected travel network.
For instance, United Express, operated by multiple regional airlines, has an extensive network connecting cities like Fayetteville (XNA), Columbus (CMH), and Evansville (EVV) to major United hubs in Chicago (ORD), Houston (IAH), and Denver (DEN). These routes are not just about convenience — they’re about opening up economic and tourism opportunities for places that would otherwise have limited access to the rest of the country.
If you live in a smaller town and need to get to a major city, your regional carrier is likely the one that ensures you have that vital link. This role is undeniably powerful — without regional airlines, these routes simply wouldn’t exist.

Conclusion: Why Regional Airlines Matter More Than Ever

As the U.S. aviation sector continues to evolve, the role of regional airlines is more important than ever. These carriers are the unsung heroes of the air, ensuring that every corner of the United States is connected, no matter how remote. From the smallest towns to the largest cities, regional airlines make travel possible. They are the lifeblood of U.S. domestic travel, driving the economy, linking people, and keeping the skies open for all.
By understanding the incredible impact of regional carriers, it becomes clear why their role in domestic aviation cannot be underestimated. These airlines are changing the way we think about travel — not just from coast to coast, but from every corner of America. So the next time you book a flight, remember: the small airline you might have overlooked could be the reason you’re flying to your destination.
