This question cannot be answered as such. Captain salary is based on the total hours on Jet in AOC environment. So the spread in GROSS is from 57500 to 89000 for Line Trainer, Regular Commander remove 6000.. So using the tool you get a MAX of around 55000 NET so 4600 net per month Highest PAY at GAC for the time being.
I am not aware of a company giving pay rise in net..
