Big changes are happening at San Carlos Airport.

Demolition is officially underway at 795 Skyway Road, marking the first step toward a brand-new, state-of-the-art facility for our airport community.

This is just the beginning, and the first of many photos we’ll be sharing as this space transforms from the ground up. We’re excited to watch progress take shape and bring a new facility to life right here at San Carlos Airport.

Stay tuned for more updates.

Hello airport fans and friends! A safe and successful airport depends on good communication, strong procedures, and mutual respect in the air and on the ground. Thank you to our pilots, tenants, staff, and community members who help support safe operations at San Carlos Airport.

San Carlos Airport supports more than aircraft operations. As a public use airport, it contributes to flight training, business access, emergency support, and regional connectivity, while also working to be a responsible neighbor to surrounding communities.

A big welcome to Ampaire’s Electric EEL (N337EE), which arrived at San Carlos Airport (SQL) on May 21, 2026. This hybrid‑electric Cessna Skymaster pairs an electric motor with a combustion engine to help reduce fuel use and emissions—and it’s already flown 30,000+ miles in hybrid configuration. Excited to see what’s next for electric aviation.

Yesterday, San Mateo County Department of Public Works brought its Road Show to County Center. It was a great behind-the-scenes look at the people and equipment that keep our county running every day.
From roads to runways, DPW’s work supports the infrastructure our communities rely on. Thanks to the crews who took time to connect with residents, answer questions, and share what they do.

Today is National Women in Aerospace Day. We’re proud to celebrate the women who keep aviation moving.

At San Carlos Airport, we see it every day: women flying, fixing, coordinating, teaching, leading, and making the kind of smart, steady decisions that keep our airport safe, welcoming, and running strong.

If you’re a woman in aviation/aerospace: thank you for what you do (and for the standards you set). And if you’re working your way in, keep going. We’re glad you’re here.
