Inyo County reviews Bishop Airport operations and draft air-alliance agreement; no formal vote

Inyo County officials received a detailed update on commercial service at Bishop Airport on Feb. 25, including capital work under way, passenger trends and a draft Memorandum of Understanding that would formalize the county's role in the Eastern Sierra Air Alliance.

The board heard that airport work already underway includes runway grooving completed in December, runway safety area design to remove "declared distances," and planning for a future commercial service terminal supported by a $2 million congressionally directed appropriation. "That put grooves in the runway asphalt to improve drainage and friction, and we've already seen the benefits of that in our rainstorm a couple of weeks ago," Ashley Helms, deputy public works director, told the board.

Why it matters: County officials said stabilizing commercial service helps secure FAA entitlement funding tied to passenger counts and offsets routine airport operating costs. Staff and the Eastern Sierra partners presented a draft cost-sharing arrangement under which Inyo County would contribute $200,000 annually toward the minimum revenue guarantee (MRG) that helps guarantee scheduled flights. Reaching 10,000 enplanements in a calendar year would make the county eligible for about $1.3 million in FAA entitlement grants for airport projects, speakers said.

Key project and operations details - Aircraft and on-time performance: United Express replaced older CRJ-700 aircraft with Embraer 175s; the county reported a 100% completion rate with few cancellations so far this season. Helms said the larger fleet lets the carrier swap aircraft when mechanical issues occur, generally limiting delays to an hour or two. "They have 200 around 200 of these aircraft in the United Express fleet versus 19 of the CRJ 700," Helms said. - Terminal and safety projects: Design is underway for a runway safety-area improvement that staff said will remove operational declared distances and reduce limitations on takeoff performance in hot or windy conditions. The county plans to replace a World War II-era rotating beacon with a modern LED fixture and keep the old unit for display. - Funding and timing: Staff said the congressionally directed spending will primarily fund environmental and design work for a commercial terminal; an additional construction grant and local match would be needed to build the terminal. Helms said FAA grant cycles for terminal construction run through 2026 and the county hopes to be through environmental review and in design by the next application period.

Air service, demand and local use County and partner data presented to the board showed growing ridership and stronger winter and holiday performance compared with last year. Staff cited a substantial increase in December and January ticket sales and higher load factors: "Because of those higher load factor numbers and the fact that flights began a little earlier in December than last year, our enplanements for December were up 49% over last year," Helms said. Exit-survey data gathered by the Bishop Chamber and partners showed over half of users were local residents and many used the service repeatedly; staff said roughly 300 survey respondents reported repeated use.

Draft MOU and expansion options Staff presented a draft MOU and cost-sharing structure that would fix Inyo County's annual base contribution at $200,000 for the core seasonal service; additional expansions would require extra, shared funding. "Rather than a sort of fluctuating, formulaic based determination of the county's contribution, we have just pinned it at a $200,000 annual contribution," a county presenter said.

Airline options outlined to the board included: adding service days in the September-to-October shoulder period (estimated +$125,000), expanding frequency within the same season (+$300,000), or adding a Saturday Denver round-trip series for peak summer weeks (+$200,000). County staff said these expansions would be cost-shared if the board and partner governments agreed.

Board direction and next steps Supervisors expressed general support for exploring modest expansion but said they wanted firm cost-sharing commitments and clearer marketing strategies before committing new county funds. The board did not approve the MOU at the meeting; staff said they would return with a finalized agreement after additional partner consultations and additional options for cost-sharing the expansions. A county official summarized available next steps: the draft MOU would be refined with partner input, and specific expansion proposals would be brought back for formal approval with explicit funding terms.

Public comment and partner perspectives John Erdeus of Mammoth Lakes Tourism said winter demand remains strong and that continued consistency in scheduled flights is key to continued growth. "The summer is far more local usage because of the sheer numbers," Erdeus said of survey results. Pat Foster of Hot Creek Aviation, speaking as a Mammoth Lakes Tourism board member and airport operator, praised airport staff: "The team at the airport does an amazing job," Foster said. Local business owner Laura Lynn Hundley urged targeted marketing to hikers and outdoors visitors and suggested advertising in outdoor and backpacking channels to attract additional users.

What the county approved that relates to the airport At the same meeting the board separately approved two project-specific contract actions tied to airport infrastructure: Amendment 1 to Tartaglia Engineering for the Beacon replacement project and Amendment 5 with Lochner for Independence Airport runway rehabilitation design (both actions were presented and carried as separate agenda items).

Ending note: County staff will return with a finalized MOU and costed expansion options after further partner discussions and outreach, and plans to pursue FAA construction grants will move forward for runway and terminal planning work.
