Airplane Luggage! Size help!?

Question

Ok so for my flight it says my carry on can be a certain weight and 45 inches. and my checked luggage can be 50lbs and 62 inches...call me stupid, but 62 inches what?!..cubic? in diameter? edges? what?!

Answer 1

45 inches is the total of the three dimensions, width, depth, height.  Generally it breaks down as 9 x 14 x 22 in as a maximum.

The checked baggage is similar, total of the three dimensions, though the actual dimensions are less rigid.  So my 26 x 18 x 10 is 54 inches, and fits in that 62 inch threshold.

P.S.  Not Linear dimension diameter.  My carryon is a 9 by 14 by 22, the linear dimension would be 62 inches (22+9+22+9) but I and many folks use these.  It's definitely the height + width + depth.

Answer 2

they talking about linear  diameter
