very straightforward but can't locate a plausible answer (to conclude a pub argument)... what are the average flying hours a commercial pilot does in a year?

i know it get's difficult to answer depending on domestic or long haul pilots, but "on average", what sounds plausible? 1,000 per yr, 1,500 per year sort of ball park. even a range would be useful.

"we" got discussing how many hours we each flew last year and i thought i was busting some to reach 250 hours "in the air", only to find the odd colleague who simply laughed at this being on the low side. so, duly chastised of course but it then led to the above as yet unanswered question.
