AI's (and indeed, most pilots of India-based airlines) are mercenaries, in the sense that they will jump ship for the smallest increase in salaries. As pointed out in another thread (which I cannot find immediately), many (or most) pilots are crazy about how much they get paid, and will fight even for a thousand bucks (INR, mind you, that's approx $20-25). Rs 15k is *Massive* by those standards !
