Mate, 80 K a month is not enough!!! They pay more in India flying for Jet airways, and that is for a year 1 Captain.
And Yes believe it or not it does cost more to train a 400 pilot than a 737. To start the 400 sim is far come complex than the 737 and therefore costs a lot more to buy. The crew that are training the crews cost more and therefore your training as a whole costs more. Your base training will also cost more try 7-10 tones of fuel an hour for the 400 just for starters.
