I often catch BR11 leaving LAX at 500:PM on Fridays. I drive from El Cajon to LAX. For the 5:00PM flight I leave at noon. I usually wind up checking in with about 1 1/2 hours before departure for this international flight, after parking lot and shuttle bus. But I have occasionally only made it with 45 minutes to spare due to traffic. I say 5 hours to be comfortable. For a domestic flight with OLCI maybe 4 hours but no less.
