The greater Los Angeles region is served by multiple airports including:

  • Ontario International (ONT)
  • Hollywood Burbank (BUR)
  • Los Angeles International (LAX)

All participants should plan on flying roundtrip to Ontario International Airport (ONT is located in Ontario, California) arriving Tuesday, June 19 and departing either Monday, June 25 (PyLith) Saturday, June 30 (ASPECT). Group transportation to Big Bear Lake, CA will be provided. Please avoid very late arriving or very early departing flights.

All participants are expected to stay the duration of the event.

ONT is the preferred airport with direct connections from most airports in the west as well as and including Chicago, Denver, Seattle, San Francisco, and Washington-Dulles.  Carriers include Southwest, American, Frontier, United, and Alaska Airlines. Flight selection is limited.

Burbank airport will typically have a better flight selection but is further.  We do not recommend LAX as traffic across the regions is wildly unpredictable (mostly bad).  Please check with us before booking these airports so we can plan transportation.  

If you are traveling from within California, please consider carpooling.

Please indicate on the registration form if you need mobility assistance due to a disability during your stay at Big Bear.

Travel support is available to cover most of transportation costs. Please apply when registering.
