In reply to kmillar99:
I'll have a look at work tomorrow but for your interest I have got my Black Ice size 3 (which is only an inch or so too long) on as hand luggage on numerous occasions with no trouble. The secret is to remove the backstay and put it in your hold luggage. Then remove the hip belt and put it in the sack. Finally, put the lid inside the body of the sack and use the top tension strap, snow valance draw cord and side tension straps to make it look as small as possible. Oh, and also, put the lid straps through the ice axe elastics to stop them dangling. If you follow all this correctly you are left with what looks like a 30L rucksack!
