I have been receiving the US version of Sky and telescope since 1978.
In 30 years of a magazine coming surface mail from Massachusetts
I think only 3 have never arrived. ( I think it now comes via a german
mail centre lately)
Many used to arrive with the clear plastic already opened, clearly
indicating good taste amongst postal workers

.
Sometimes I used to get them in the wrong order...ie
December's then November's then October's issue.
I think that is a pretty good average for 30 years.
Probably the only frustrating thing was for a magazine to come
tens of thousands of miles only for the Aussie Postie to fold it in half
as he put it in the letterbox, ruining the glossy front page pic
