I think that the general consensus is to expect 1000 x hourly rate at UPS to estimate annual salary. However, international is higher by probably 20%. None of this includes extra flying beyond your normal schedule. If you are able and choose to accept junior manning calls from scheduling you can make a lot more. I have some friends who are F/Os making CA money. The current ANC 747 pilot shortage is a completely different discussion. I wouldn't plan on that for future earning potential.
