I was worried about the same thing, I have 3 speeding tickets in 16 years with the most recent one about 3 years ago. I have an interview with SWA in a couple weeks so I guess they weren't too concerned. That being said, I'm sure they aren't psyched about them or else they wouldn't ask. I do know of a guy who was interviewed and hired with 5 tickets on his record. Just some frame of reference for you, I don't know what the official stance is. Good luck!
