Cheapest Airlines currently is AirArabia.

Found Airarabia is the cheapest Airline for some sectors in India. GoodNews is that FlyDubai has also started flying to many locations in India.

I wish some one would explain us the Tax difference. In the snapshot below for the Kuwait - Sharjah - Hyderabad sector for the Lowest Fare KD 42/- the tax is KD 36.690/-.

In the next snapshot

For fare KD 65.380 the Tax is only KD 20.540, now many doubts are arising where the Tax money goes on.
