When travelling across the seas i will have to check my backpack in as luggage in the airport and i was just wondering if i should keep ALL my money in my carry-on. I know that the airport is bustling and crowded and i don’t want to take the chance of having it stolen (even though i will stow it on several areas of my person). Is it more at risk in my backpack, which is out of my sight (even though it will have locks) or on my person???
