Carlsbad, California – United Airlines to Resume Flights at McClellan-Palomar Airport

Carlsbad, California – The San Diego County Board of Supervisors has approved a three-year lease agreement with United Airlines, allowing the airline to operate four daily flights from McClellan-Palomar Airport in Carlsbad. The service, set to commence in March 2026, will include two flights each to San Francisco and Denver, utilizing Embraer 175 aircraft. This decision follows United’s previous service at the airport, which ended in 2015 due to aircraft size limitations. The return of United Airlines marks a significant development in the expansion of commercial flights at Palomar Airport, which has seen increased activity in recent years.

Community Response

The approval has sparked considerable opposition from Carlsbad residents and local officials. A substantial majority of public comments submitted prior to the meeting expressed concerns over the potential increase in noise and environmental impacts associated with the additional flights. Residents have advocated for greater local control over airport operations, emphasizing the need to maintain the airport’s community-focused and friendly environment.

Legal Considerations

In response to the Board’s decision, the city of Carlsbad, along with local groups, has initiated legal action, arguing that the approval violates the airport’s conditional use permit, which restricts its use to general aviation purposes. The next hearing in this case is scheduled for December 19.

Background

McClellan-Palomar Airport has been operational since 1959 and serves as a hub for both general aviation and commercial flights. The airport has undergone several improvements over the years, including a $24 million renovation in 2009 that added a modernized terminal and other facilities. The recent expansion of commercial services, including the return of United Airlines and the earlier addition of American Airlines flights, reflects a broader trend of increasing air travel options in the region.

Looking Ahead

The introduction of United Airlines flights is expected to enhance connectivity for travelers in the North County area, providing more direct routes to major cities. However, the ongoing legal challenges and community concerns highlight the complexities involved in balancing development with local interests and environmental considerations. The situation continues to evolve, and further updates will be provided as new information becomes available.
