Best suitcase for my 1-4 week business travel is an American Tourister - hard sided lightweight expandable spinner with TSA combination locks and a 3 year worldwide warranty. I have been around the world about 4 times in the past 24 months with approx. 200-250 flights and the suitcase is going strong with normal signs of wear and tear. However, I have completely worn out one wheel that requires replacing. Apart from that, I am hooked on this brand which I believe is a Samsonite brand.
