What everyone else said, I think it would suck in winter, but I will add that a bike box from a bike store will work for size. Yes there are diff size boxes, but I've flown with a 54, 56cm 700 wheeled bike and boxed it easily enough with only front wheel and front rack removal. Rear wheels and rear racks have always remained on bikes, 26in or 700 bikes I've flown with.
in other words, don't worry about the 62 inch thing
I've generally used the smallest box the bike can fit in, as it's better for the bike (held in solidly , fork not moving back and forth, but also because its easier getting into out of a car and moving on the airport trollies within airports and getting through passageways.
somewhere I've written down the dimensions of the best size box for my present tourer.
This photo was a box on the smaller side, with a 26 mtb of about 56cm. Some boxes could be a good 6, 8 inches longer, so compare and note measurements if you go to bike store looking.
