I'm mainly thinking of it as a way to transport my camera bag plus a few other things in the airport as one bag. Once at my destination, I figure I'd unload the backpack at the hotel and either leave it there or carry it around pretty much empty with my camera bag at my side. And if I got into a situation where I didn't want the camera bag and cameras ready at my side, they could all go in the backpack and I could forget about it.
That's what I've done on a couple of trips, but airport security keeps asking me to take out my little domke full of m8 & lenses, which is invariably at the bottom of the backpack, making for more hassle than I'd like.
none of which is as bad as my last flight, where dutch security decided to commandeer my lunch.
"we can't let you take that on the plane."
"why?"
"because it's liquid"
"it's not liquid–it's stew!"
"i'm sorry, but there's a rule"
"against lamb and potatoes? it's not a liquid, it's my lunch!"
"there's liquid in it."
"there's more liquid in my body..."
"sorry... you can write to the eu government if you want."
"thanks. enjoy my lunch..."
🙁
