OT: Camera bags for travelling

I'm trying to figure out what camera bag would be good for travelling on airlines. Would a roller type be best (to get off shoulders) or is it not a good thing to be rolling around camera gear. I was looking at a Delsey Camera Bag Pro but can not find any reviews. Another is the Tenba Shootout backpack/roller. Any suggestions? Thanks for any input.

I bought a Tamrac Roller Bag. It not only holds all my gear (and then some), there are some small Tamrac bags that are designed to slide down over the roller bag's handle. The small bag is great for the little stuff you want to carry aboard ... like a decent sandwich from home or the airport instead the overpriced nonsense they offer on some planes. Once I get to my destination, the small bag serves as a small walk-around bag for a limited amount of gear.

I've used a myriad of bags for aircraft travel, but my next one will be a roller bag - probably from Thinktank Photo.

I use a backpack and have customized it. On stairs and other obstacles it's easier than a roller bag, I can move faster with it and it weighs less.

I bought Andy Bigg's Gura Gear Kiboko backpack for air travel. It only weighs 4 lbs empty, that means I can carry more actual camera equipment on board, which is especially important when some airlines (international) limit one's carry-on weight to 10lbs-20lbs. Roller bags weigh too much empty. And a 10-20lb backpack is easy to manage down airport concourses and airline aisles.

My, such different responses. I spent some time googling the brands. I have never heard of the Kiboko and it sounds very interesting. Did you feel the lighter padding was sufficient for a klutz like me?

I have used some backpacks successfully. The LowePro Photo Trekker is about max carryon size. Wears decent for a backpack. Can even haul large format. I moved my digital kit to a LP Flipside 400 backpack. My new fav photopack. It is carryon re, and carries well. Since you can access pack with it still on it is safer than a reg pack you have to take off to access i.e. you are wearing it while photographing and it is not on ground to make it easier to steal.

I use a LowePro Nature Trekker backpack. It holds all my stuff, is pretty comfortable and fits in the overhead (although it's a little tight).
When I have absolutely had to put stuff in checked baggage, I have used a large Pelican case with TSA style padlocks.

The lighter padding of the Kiboko is sufficient. It come with way more padded dividers than anyone could possibly use, so I used some as an extra thickness around the perimeter of the bag. The design of the exterior pockets makes the bag look smaller and lighter than it actually is which is a good thing when approaching an airline gate where attendants are visually gauging everything people are carrying.
