This travel tips mentions:
The maximum number of linear inches on a checked bag for most airlines is 62 inches. This means that when you add up the length, width and height of the luggage you intend to check, it should not be more than 62 inches.
I'm in the market for as large a duffel bag that I can bring on a domestic US flight. Perhaps
32L, 15W, 15H, or
38L, 12W, or 12H. It doesn't matter as long as it hits 62 linear inches.
However, a quick search of Amazon reveals no duffel bags that are exactly 62 inches. The closest I found was this one at 55", but all of the other "large" duffel bags peaked at about 50".
What brands for duffel bags are exactly or near 62 linear inches?
Is it possible that companies don't make them exactly 62 inches because packing it to capacity could make it bulge greater than 62 inches?
