i have flown hundreds of times and only checked twice and that was due to moving or carrying equipment
some international carriers are more restrictive than US carriers (i.e. smaller dimensions, lower weight limits)

This is particularly true of business travellers who require tools or equipment. Airplanes have cargo holds for a reason.
