Mark, Champion has unscheduled ops into LAX usually 727-200s and usually in from Vegas. Air Tahiti Nui is in here daily and sometimes twice daily with A340s (they have 4). Corsair flys 747-300s in from Paris-ORY enroute to Papeete Tahiti and return. (Once or twice weekly) And Omni Intl' does a series of unscheduled DC-10 charters. Spirit Airlines does daily MD80 runs from Detroit. And Trans Meridian..well you just don't when they'll show up. I've seen their 727s here doing work for Sun Country. And reportedly they've brought in a few A320 flights, but again, they're not scheduled. Most likely charters and can come from anywhere. Hope this helps, greg
