What is the maximum size and weight for a rucksack if you want to have it as carry-on luggage on flights? I'm planning a round the world trip for next year (in mainly warm/tropical countries staying in hostels etc with no skiing ) and I'm currently sorting through the minefield of information surrounding backpacks. I'd like to make it as easy as I can on myself and I'm hoping to travel quite light so I'm planning to limit my pack size to around 50L. Will this be too big for carry-on luggage?
I'm looking at Arc'Teryx, Osprey and Macpac backpacks at the minute........but the Arc'Teryx Bora 50 in particular - does anyone have any opinions on this/these?
Also - is a daypack absolutely necessary?
Most airlines permit bags up to the following dimensions (in inches): 22 inches high, 14 inches wide, 9 inches deep. A 50L rucksack, assuming it doesn't have a hard back, could POTENTIALLY be squished to fit in those dimensions, but my guess is that you'd run into issues with that at some airlines. Here's a link that discusses the rules in general, but each airline has their own specific rules that you need to follow.
One of the problems with just doing carry-on is that you can't carry some items that could come in handy during a RTW trip, like small knife or a bottle opener.
Also, I think you'd need to get a short backpack, which might not be comfortable for long walks if it doesn't sit on your back right.
I'd recommend a day pack, at least so you can carry around just the estenials when out for the day (toilet paper, your camera, some water, a pull-over in case it gets cold, etc.) You don't want to be walking around with all your stuff every time you go out.
I think Greg is right. Post 9/11, you simply cannot bring everything onto the plane that you would like for your RTW trip. Bite the bullet, check your main bag. A day pack is handy so many times that yes, I think it is a necessary item on your trip.
Thanks for the replies and info guys. I think you're right...I'm just paranoid about checking my bag in. It's bad enough if you're on a 2 week holiday and it goes missing!
Probably something that can work is take a backpack that can be a carry-on, then check your items in another bag that will get pulled from airline security, this way if it is lost you still have your main pack.
