Werent they going to land at John wayned first, the shortest strip in California? Or did I miss-hear? I wonder if DenverDitDat is lurking on this, he's a 320 instructor.
No, I don't think they serve John Wayne/SNA. They do go to Burbank, and have lots of flights in Long Beach, and some at Ontario.
The runway at SNA is short, I am amazed when Aloha flies 737-700's out of there to HNL, and with the noise restriction takeoff.
