I flew from Portland to Sacramento in early March, carried on the stand and gear bag. No questions leaving, but on the flight back they had to take a look at the SLA's since they couldn't view thru them on the xray or something.
No probs with gear, but they looked at my cigar punch a little funny (had one on my keychain) was kinda funny, guy looking at it all funny with the "wtf is this?" expression on his face.
