I'm leaving the states for a year for work, and although I already shipped a couple boxes over to the destination country, I still have a bunch of clothes I'd like to cram into my suitcase. I picked up a suitcase that's a tiny bit taller than most (30"); the dimensions listed on the site are 30" x 21" x 13". Meaning it's 64", exceeding the 62" limit. And that's not including the wheels (which United says it doesn't include anyway).
Are airlines (United, specifically) heinously anal about luggage dimensions? I'd hate to pay $100+ just because my damn suitcase was 2" larger (which is incorrect, because the suitcase is wider at the base than at the top).
Also.. Since I want to cram as much into the size/weight restriction as possible, what would be the best type of suitcase to get? Instead of a nylon cloth suitcase, should I get one of those shell suitcases? Any advice/insight is greatly appreciated. Thanks!
