I'm with Stupid - incorrect
Level 1 rarely if ever used
Level 2 if you have a ATPL
Level 3 1000 hrs on jets OR 500 hrs on 737....
Level 2 qualifies for level 3 upon reaching 500 hrs on type don't know if level 1 goes to level 3 with 500 hrs on type - I assume so.
Base pay for a Captain is $131600 if my maths are correct - plus extra for C & T, extra when the international ops start, extra if we agree to new work rules, PLUS a profit sharing bonus at the end of the financial year. Allowances go on top of that figure.
F/O's a percentage of the Captains salary dependent upon level.
