I'm not sure of regular flights, but usually at Van Nuys airshows or at Burbank airport, once in a while B17 'Nine O' Nine' & a B24 have rides you can buy, at $400 (If I remember correctly) for a 1 hour flight. They were at the Van Nuys show in May, so I'm not sure when they'll come around again, but they also have seperate flights (like they'll show up at the burbank for the weekend). You might wanna check at both airports for info, I dont rememeber the name of burbank's private airport, but right next to the main part.
