California Pacific Airlines (San Diego McClellan Palomar) ended all operations on January 16 and subsequently furloughed nearly all employees on January 18, The San Diego Union-Tribune has reported.

The carrier's website currently features a simple announcement saying that all flights have been cancelled without any further details.

Flightradar24 ADS-B data shows that the airline ceased to operate its Essential Air Service (EAS) route between Denver International, Pierre, SD, and Watertown, SD on January 15. It had previously terminated all commercial operations out of San Diego McClellan Palomar at the end of 2018, citing pilot shortage as the reason.

In a letter to the US Department of Transportation from January 29, CPA said it continued "internal reorganization efforts in the interest of restarting operations. The relaunch is planned to be limited to Supplemental operations as well as scheduled service with a Carlsbad, California hub." CPA further said that it had no intent on resuming its EAS services to Pierre and Watertown.

The carrier inherited the EAS from ADI Aerodynamics (Pontiac Oakland County International), which it acquired in 2017.

In the letter, CPA also said that its owner, a 96-year-old golf mogul Ted Vallas, was planning to acquire a further two aircraft for the airline and recall employees "soon".

CPA operates four E145, all of which are currently grounded.
