County of San Mateo Airports

Friendly community airports serving the Bay Area and beyond

The County of San Mateo manages two airports, San Carlos (SQL) and Half Moon Bay (HAF), which serve the bayside and coastal communities.

Both airports are important assets to our community. SQL and HAF host local businesses, contribute to the economy including creating hundreds of jobs, are the base for emergency services, and support the training of current and future aviation professionals.
