[Littlepeahead]

I travel with my camera gear as hand luggage and never have any problems.

I find this bag really useful as gear goes in the lower part, space for memory cards and other bits in the internal pockets and then the top can be used for your book/kindle/ipod/passport etc. and it is small enough for the overhead locker. Costs about £70 and my one has lasted 7 years so far without showing any signs of wear.
