I typically buy new luggage every couple of years, usually a different size, so they end up lasting about 5-6 years each. That said, I usually take 30-40 international business trips per year. When you travel with suits, it is best to find one that helps fold them nicely and keep them folded moderately tightly while in transit. Unfortunately, my favorite model isn't made anymore, though I keep a lookout for similar models. Probably the best built model I have is a 22in Tumi that my wife bought for me for a birthday or something a few years back. I still have it, and it is in great shape. However, it was very expensive. I still have a few years of heavy travel left, so I'm considering getting a mid-size Tumi, if it holds suits well. When we go on vacation though, I never use the suiters, just a big enough suitcase to hold the clothes and DWs souvenirs....R
