Why would a two leg commute be a problem?
. . . There's a very long thread about a turboprop crash at Buffalo [USA] where it was discovered that both pilots had commuted live into their flight out of EWR; one from Florida, the other from Seattle, a lengthy 2 sector commute.
Commuting
is a problem because it eats up your off-days; and if you commute on your rostered workday it shortens your rest period and technically makes you illegal duty wise, because "commuting" is not part of a rest period.
It's a self evident, common sense sort of issue.
