Google OPEN LUGGAGE PEN and watch the video how to open zippered luggage without a key or combination numbers. Shocking. I just got this new bag because it is harder to open with an awl to spread the zipper teeth apart. But still someone can just cut it open with a razor knife. Be smart and just take clothes and disposable toiletries you won't miss if the whole bag disappears. Wear your valuables and carry them aboard the plane in your backpack or carry on which has NO zippers. Hope this educates you and forces all luggage manufacturers to stop making zippered goods. Will see if my new bag holds up on my next trip to Bangkok.
