Luggage locksUsing a combination lock means there's no key to lose, but if you forget the number, you have to buy a new lock. These new TSA-approved luggage locks from Master Lock use letters instead of numbers, which means you only have to remember a four-letter word. The Set-Your-Own-Password Combination Locks cost $12.26 each. masterlocktsa.com
