Bangkok Airways
I started out in 2003 as F/O on ATR 72-500. Basic salary was THB 45,000/month (yeah, I know.....we are ont of the lowest paying pilot in the world). I dont know the THB / INR conversion, but it was THB 40/USD in those days. Per diem is different for each sector.
Now I am F/O on A320. My basic salary is THB 50,000 / month plus per diem of around 25,000-45,000 depending on my monthly schedule. O/T starts from the 71th hour at THB 400 / hour.
I think we are one of the lowest paying A320 pilot in the world.
