I am looking to purchase a Billingham 555 bag in the near future. I would like to be able to use it as a carry on bag on airplanes. My intent is to put two camera bodies (6D and T2i) , a 15-85, 70-200 f4, some accessories, and a change of clothes in it for air travel. Have any of you used a 555 as a carry on bag? According to the dimensions, it appears that it is small enough to fit overhead but I want to make sure before I purchase it. Thanks!
