Windfall tax on aviation fuel slashed. Will air tickets be cheaper?

There is a substantial cut in the Aviation Turbine Fuel (ATF) windfall tax, lowering it to ₹1.5 from ₹5. ATF makes up around 30-40% of the cost of running an airline in India, and a decrease in its prices will boost the profit margins of companies. But will this gain be transferred to the consumers too?
