Buy A Good Suitcase You'll Use Forever — Unless you're an extremely light packer or super-infrequent traveler, you'll want a suitcase that'll last you at least 250,000 miles (that's 10x around the world, for the Frequent Flier-savvy). And don't worry about getting it beat-up — if there's anything more depressing than an unstamped Passport, it's a suitcase without scuffs.
