If you are asking about the TSA PreCheck Mobile van that is stationed at the Santa Barbara Airport for the next week then the answer is: June 24-28 and July 1-3, 9am-5pm. Reservations are suggested but you can walk up to the van and get registered as well. Here is further information regarding that: universalenroll.dhs.gov
Doesn't really matter, it is the fastest tsa check you will do
Usually open if their staffing allows. The pre check is in the same location as TSA at the top of the escalator.
