First off, no support for the TSA from me. ; You know what the GA (general aviation, private pilots) community calls the TSA? ; Thousands standing around. ; There are stories of small GA airports with their own TSA agents that really do nothing, but have to be there because of regulations. ; Yeah, you'd think that if the TSA had a legitimate function the aviation community would appreciate them but they're pretty much uniformly despised. ; I want to try to stress that my anger isn't directed at the individual guards, mostly the ones I've dealt with have been pretty decent, except for one insane example, they're "just doing their jobs". ; That one example was weird.. I inquired about the possibility of doing a hand inspection of my camera because I'd heard that the X-ray machine might damage the sensor, it seems not likely to be true but the suggestion was that the x-rays might cause hot pixels. ; So I asked this woman about it, and her response was "THAT'S A LIE!". ; Very angry, like I'd just accused her of something.
This bag size thing is a mess, but I don't blame it on the TSA. ; Long before the TSA we had official carry on restrictions. ; Which had been largely ignored, and still are until carry on capacity limits are reached, then the airlines kind of have to start cracking down, once all the carry on space is used up there really is nowhere else to put extra carry on bags. ; I expected much worse than what I've seen so far, when I flew to WDW this year I actually flew with more carry on baggage than I have in a long time, my usual backpack jam packed with camera gear and some electronics that I don't trust to checked baggage plus another backpack that was a bit less tightly packed with an extra lens, an external hard drive, and some other stuff. ; I was afraid they'd nix that, but I didn't get any hassles.
Considering the number of people walking on the plane with large rolling bags plus backpacks and such it was only fair that I was let on, but I felt kind of conspicuous walking on with two backpacks. ; As a good little traveler I crammed by large pack under the seat and put the small pack into the overhead where it took up minimal space and left plenty of room for those monster roller bags everyone else was bringing on.
However, as to tripods.. I've never tried to carry it on. ; Because there the TSA does get involved. ; They of course have their list of prohibited items, but as has been pointed out the guards at the checkpoint can pretty much decide whatever they want is prohibited. ; And, as far as I can tell, can immediately arrest you for trying to carry a prohibited item through the checkpoint even though they only decided it was prohibited then and there. ; I too figured that a tripod could be considered club like, and so packed it in checked baggage. ; I wasn't happy doing that, but I did the best I could, putting it in a tripod bag (a thin skinned case) and stuffing the bag with socks and underwear and such for extra padding. ; And then putting that bag in the largest suitcase I had available. ; It barely fits. ; It seems to work, I've done that on two air trips so far. ; It makes me nervous every time, but I absolutely have to be able to do night photography, it's my thing.
