Hi,
I'd just add some recent experience...
I was flying from Sweden to Idaho, route Sweden-Paris-Salt lake City-Idaho Falls, with Delta. I had a tripod in checked luggage and had a Gura Gear Kiboko bag with:
1 Sony Alpha 900
1 Sony Alpha 700
Sigma 12-24/4.5-4.6
24-70/2.8
16-80/3.5-4.5 (which plays nice with the Alpha 700)
70-300/4.5-5.6
400/4.5
1.4X and 2X extenders
100 mm macro
Batteries, RRS pano head, Arctic Butterfly and other small stuff
I addition I had a notebook in a small "Swiss" case and two 3.5 SCSI drives in the Kiboko. The drives were needed for the business part of my trip.
Delta partner KLM actually weighted my Gura Gear Kiboko but ignored the Notebook case. Although I was booked on a Delta flight KLM applied their wight limit of 12 Kg and I was over that, probably because of the extra harddrives. I removed my Alpha 900 and the 24-70/2.8 from the Kiboko and put them into my west. That was OK, but I was told that I was not allowed to put them back into the bag.
The last part of the flight was from Salt Lake City to Idaho Falls on a Canadair regional jet (CRJ 700?). I removed everything from the pockets of the Kiboko and it would easily fit to the overhead bin.
This was strictly a business trip but with photo opportunities during week ends in Yellowstone and Grand Teton NPs and the Craters of The Moon park.
Best regards
Erik

I've always taken my camera gear as carry-on. It has never been a problem for me flying domestic US flights so far. I've never seen carry-on items weighed, and even the largest of camera backpacks is going to be smaller than a lot of stuff people carry on these days. The only issue is if one of your flights is on a small regional jet with tiny overhead compartments; you may have to gate-check your bag unless it's been specifically designed to fit on such planes (I have one of the smaller ThinkTank backpacks for just this scenario).
The tripods go in the checkked luggage - in separate bags since between my wife and I we take multiple suitcases anyway. Part of my reason for bringing two tripods is that I prefer the smaller/lighter one for long hikes. But I also figure the chances of both of them getting lost or stolen on a single flight are extremely low. So far I've never had any incidents, even though my luggage has sometimes had the TSA notice of inspection in it when we get to our destination. I figure tripods are a pretty low-risk item for theft, because even if someone is savvy enough to know their value, the sheer size and bulk of them makes them much less appealing to a would-be thief, than smaller valuables that could more easily be stuck in a pocket without attracting notice.
