Am not surprised. I had to book a MAA-BOM-MAA for yesterday's travel (booking done 10 days back) for which I paid INR 6700 (0 base fare, 800 taxes, all fuel surcharge). But here's another interesting thing. I had to cancel the ticket for circumstances beyond my control. When I cancelled a ticket on a similar class (which INCLUDED a base fare) last month, I had to forfeit the entire price including tax and surcharge. This time, they gave me a full refund...don't know if that's a system issue I benefitted from this time or lost the last time !
