3000 hours. No ATPL? What on earth have you been doing?
Considering you need 1500 hours for an ATPL and OP only has 300 then that might have something to do with it.
Not sure where you got 3000 from...
I'm about to turn 41 with just over 300hrs TT, an Australian CPL/ Multi Engine Command Instrument Rating and all ATPL subjects.
