Well, I'm sorry I won't be reading another Foothills Trail report, but I will look forward to reading all about this one.
Anytime I fly, I do carry on only. If I want something, like a knife, I pick it up locally (for a scuba diving knife, I pick up a steak knife with a plastic handle from a restaurant and break off the tip and toss it before I leave). I hate that the TSA makes it so hard to travel, but back on topic, your gear seems like it shouldn't give you any issues. I will reiterate the need for a light UQ.
