Mammoth Yosemite Airport (MMH)

Mammoth Yosemite Airport (IATA: MMH, ICAO: KMMH) serves as the primary air access point for the town of Mammoth Lakes and the surrounding Eastern Sierra region of California. It is a small public airport providing a crucial link for tourists, particularly during the winter ski season. Opened in 1947 and owned by the Town of Mammoth Lakes, the airport initially catered to general aviation. Over the decades, it underwent upgrades to accommodate commercial passenger service. Its name reflects its role as a gateway not only to Mammoth Mountain but also to the eastern entrance of Yosemite National Park via the seasonal Tioga Pass Road.

The airport is situated approximately six miles east of Mammoth Lakes, just off U.S. Route 395. Travelers typically reach the town and nearby ski resorts via pre-booked shuttles, rental cars, or hotel transport services. Operations at MMH are predominantly domestic and highly seasonal, with a significant increase in flights during the winter months. Scheduled commercial service is primarily provided by United Express, offering connections to hubs such as Los Angeles (LAX) and San Francisco (SFO). Additional public charter services may be offered by other carriers. The airport does not handle scheduled international flights.

The facility consists of a single, small terminal building designed for efficient processing rather than extended stays. Amenities are limited but functional, including airline check-in counters, a TSA security checkpoint, a waiting area, and rental car desks. A small cafe and gift shop are typically available for passengers. There are no airline lounges or extensive retail options.

For travelers using Mammoth Yosemite Airport, planning is key. Arriving 90 minutes prior to departure is generally sufficient, but it is wise to confirm with the airline. Due to its high elevation of over 7,100 feet, the airport is susceptible to weather-related flight delays or cancellations, especially during winter storms; monitoring flight status is recommended. Ground transportation, including rental cars and shuttles, should be booked in advance as on-demand availability can be scarce. Visitors should also be aware of the high altitude and stay hydrated upon arrival.
