just to add to this.....
F/O Regional = approx 50,000 p/a
Capt regional = approx 90-100,000pa.
F/O LCC (ie jetstar or tiger or virgin) = approx 100,000 pa
Capt Lcc (see above) = approx 170,000pa
these are VERY approximate figures. BUT just to inform you of what you are looking at for where you ultimately set your sights. There are NO guarantees that you WILL or WON'T make the position you desire.
RFDS is PROBABLY the cream of GA positions.... and they pay in the order of 85-95k pa including allowances.
Having said all that... I have enjoyed my life so far, which included many years and beers in GA. I have yet to amass my fortune as an airline pilot, but am enjoying the lifestyle so far.
I do NOT have a degree.
good luck, which ever way you choose to go.
