TEMPO.CO, Jakarta - America’s strength as a global powerhouse lies in its seamless cross-border connectivity. Even its smallest international airports play a surprising role, quietly upholding the nation’s far-reaching influence. These modest gateways prove that big impact doesn’t always require a massive runway.
Smallest International Airports in the US
Lonely Planet and Simple Flying named Bozeman Yellowstone International Airport and Key West International Airport as two of the smallest international airports in the US. Other formidable getaways sharing the same reputation also include:
1. Key West International Airport - 334 acres
Key West International holds the title of the smallest international airport in the US, with only 334 acres in use. As a tourists’ favorite, this transportation hub connects Key West’s picturesque beaches to other regions across the country. With a history tracing back to 1913, this airport has had a productive growth in capacity over the years.
2. McAllen International Airport - 370 acres
Operating with two asphalt runways, McAllen International Airport is the second smallest international airport in the US. Though the hub envisions a bright future of expansion, only 370 acres are currently in active use in Hidalgo County, Texas. Thanks to its strategic border location, McAllen International Airport serves as a vital link to two key destinations in Mexico.
3. Portland International Jetport - 726 acres
Portland International Jetport may be Maine’s largest air hub, but it still retains the charm and scale of a smaller airport. Spread across 726 acres, it operates just 11 gates serving both domestic and international routes. With soaring wooden beam ceilings and sleek steel supports, the terminal’s coastal-inspired design offers a breezy, spacious feel that captures the spirit of New England.
4. Burlington International Airport - 942 acres
Burlington International Airport, often cited as one of the smallest international airports in the U.S., serves up more than flights, as it is home to the most locally sourced airport restaurant in the country, giving travelers a true taste of Vermont. Spanning 942 acres, it treats visitors to stunning views of the Green Mountains right from the terminal. With two runways and ten active gates, this vibrant hub remains a vital lifeline for the Burlington community.
5. Bozeman Yellowstone International Airport - 2,481 acres
Bozeman Yellowstone International Airport may be small in size—often ranked among the smallest international airports in the U.S.—but it offers travelers a cozy, scenic gateway straight into Montana’s mountain charm. With sweeping windows that frame the breathtaking Bridger Mountain Range, the airport feels more like a rustic lodge than a travel hub. For thrill-seekers and nature lovers, flying in here is the perfect start to an unforgettable Yellowstone National Park adventure.
6. Kona International Airport - 3,450 acres
Kona International Airport, Hawaii’s primary gateway, stretches over 3,450 sun-drenched acres adorned with open-air pavilions and swaying palm trees. Its unique design lets travelers move freely while soaking in the island’s fresh and tropical breeze. Adding to its charm, KOA offers comfort and efficiency with 11 covered gates seamlessly blending style and convenience.
7. Savannah/Hilton Head International Airport - 3,650 acres
Previously known as Savannah Airport, this bustling hub has earned its place as Georgia’s second busiest, despite operating with just a single terminal. Located just 13 kilometers from downtown Savannah, it punches above its weight with a surprisingly full flight schedule. Its convenient proximity and nonstop energy make it a standout stop in the Peach State’s air travel scene.
