Maine has a distinct culture and cuisine despite being one of the least populated states in the country. Much of Maine is still untamed country where no one lives. Exploring the land can lead to unexpected adventures, whether you’re a bright-eyed tourist or a local who thinks they’ve seen it all.

Maine has four major and two minor commercial airports. There are also dozens of general aviation airports for private planes, mail carriers, etc.

Here, we will dive into Maine’s six commercial airports. 

1. Bangor International Airport (BGR)

Location: Bangor 

Size: 2,079 acres

2022 Enplanements: 346,166

When you fly to Maine, there’s a good chance that you’ll land in Bangor. Bangor International Airport is the biggest airport in the state, stretching over an enormous 2,079 acres of land. It used to be an Air Force base. 

Today, Bangor serves as a major hub, connecting many East Coast cities. Canadians and Europeans often stop here, too. Bangor itself is an attraction for many travelers. It’s a gorgeous city just an hour from the famed Acadia National Park.

Over 300,000 passengers boarded planes at BGR in 2022, a healthy number that also makes the airport one of the busiest in the state.

2.  Presque Isle International Airport (PQI)

Presque Isle’s airport handles a lot of student traffic.


Location: Presque Isle 

Size: 1,489

2022 Enplanements: 15,428

Presque Isle is a small town, and its airport reflects that. Presque Isle International Airport typically averages around 12,000 – 15,000 outgoing passengers annually.

A big chunk of those flyers are students flying to the University of Maine or Northern Maine Community College campuses in Presque Isle. Another sizeable group is Newark passengers with a layover. 

PQI isn’t the most trafficked airport on this list, but it does rank high on acreage. It measures 1,489 acres.

3. Portland International Jetport (PWM)

Location: Portland 

Size: 726 acres

2022 Enplanements: 982,834

Most people who fly to Maine will end up at Portland International Jetport. It’s not one of the biggest airports in Maine when you look at its relatively small 726-acre size. 

However, PWM is very busy. Almost one million passengers flew off Portland runways in 2022. Its popularity springs from the city itself. 

Portland, Maine, is a famously trendy spot. It’s recognized worldwide for its inventive cuisine and laidback, accepting culture. Visitors fly here to soak in the ambiance and see famous sights.

4. Knox County Regional Airport (RKD)

Location: Rockland 

Size: 538

2022 Enplanements: 11, 200

Knox County Regional Airport blooms in the summer, when traffic increases significantly. It’s a favorite landing spot for private jets carrying vacationers.

RKD originated in World War 2. It was the Rockland Naval Auxiliary Air Facility (NAAF) until 1946. Decades later, Knox County took control and gave the airport its current name.

Perhaps the most interesting thing about this airport is the Owls Head Transportation Museum. It’s located on an abandoned runway and features antique planes and cars. It’s a fun spot for enthusiasts to immerse themselves in history.

5. Hancock County-Bar Harbor Airport (BHB)

Size: 468 acres

Private jets often land at Hancock County-Bar Harbor Airport, too. It’s located in Trenton, Maine, an area close to outdoor luxury havens and summer colonies. Even President Barack Obama once landed Air Force One at BHB before going on vacation.

The airport’s landings used to be more stressful. BHB was a naval air base between 1943 and 1945. 

Currently, general aviation represents the vast majority of the traffic at this 468-acre runway. 

6. Augusta State Airport (AUG)

Location: Augusta

Size: 406 acres

2022 Enplanements: 5, 804

Augusta is the state capital but doesn’t see the heaviest traffic. Neither does its tiny airport. Augusta State Airport typically processes less than 6,000 passenger boardings per year.

Maine owns the airport, but Augusta manages the day-to-day operations. Because the passenger count is so small, AUG is only connected to one commercial airline. 

The airport first sprung into being under the New Deal.
