November 2007 - Proposed Air Service 
Horizon Air proposed to conduct scheduled service from Los Angeles International Airport (LAX) to Mammoth Yosemite Airport (MMH) using their Bombardier DHC 8-402 (Q400 Dash aircraft. The Q400 Dash 8 is part of the Bombardier Dash 8 family of turbo-propeller driven passenger aircraft. The Q400 Dash 8 can seat up to 76 passenger aircraft. The Horizon Air has provided the Federal Aviation Administration (FAA) with a letter of intent to initiate winter ski season passenger service into MMH.
Horizon Air is proposing to begin scheduled regional air carrier service to MMH beginning in December 2008 with two flights per day from LAX during the winter ski season (approximately December to April). The Town of Mammoth Lakes has prepared and the FAA has approved a forecast of future commercial aviation activity at MMH. Winter ski service is projected to increase to a maximum of eight flights per day by the year 2011. Summer service is projected to begin in 2012, with 2 flights per day to LAX for 8 weeks in July and August. 
The approved aviation forecasts predict that the number of flights per day would increase from two to eight as additional regional markets such as Las Vegas, Northern California, San Diego, or an alternative Southern California market are added. The Mammoth Mountain Ski Resort would subsidize the winter ski air service. The projected summer air service would not be subsidized.
Scheduled daytime commercial air service would start with one morning and one afternoon flight. No aircraft would be scheduled to remain at the airport overnight. The proposed air service would utilize the existing MMH runway and taxiway system.
Construction of new airport facilities are not proposed. Winter service is not expected to exceed eight flights per day due to airport facility physical constraints (e.g. aircraft apron space and terminal capacity).
Proposed FAA Action
Approval of the proposed amendment to operations specifications for Horizon Air to permit scheduled commercial air service to MMH using the Brombardier Q400 Dash 8 aircraft pursuant to 14 Code of Federal Regulations (CFR) Part 119.
The establishment of scheduled commercial air service into MMH also necessitates a change in the MMH Operating Certificate from Class IV to Class I, pursuant to 14 CFR Part 139. Airports with a Class 1 certificate may accommodate scheduled service by aircraft capable of carrying 30 or more passengers, while airports with a Class IV certificate may accommodate unscheduled service by aircraft of similar size.
