Where do we park?
Parking at each FBO has the potential to be different and we will be sure to inform you if that is the case. We enocourage all passengers to be dropped off at the FBO. However as with any normal charter, parking should be provided at the FBO. Should you have any questions, or concerns about parking, please call 800 iFLYJSX. Please note that parking at Buchanan Field in Concord is free.

My guess is
this lot. The flight schools have their own lots and pilots that have a hangar usually have ramp access so they can drive right up and park their car inside their hangar. That would just leave a few random pilots who need a place to park.
Three flights a day at 30 seats each I think this would be sufficient for the near future, but I don't see much expansion for JetSuite out of CCR unless they build a garage or more parking (and expansion would come with a whole host of other issues anyways).
