Anyone that flies frequently in the domestic skies will know that airfares have been on an absolute roller-coaster ride this year as airlines do everything they can to strike the right balance between price and number of seats filled.

The graph below visualises what the roller-coaster looked like for the first half of 2009. The blue line shows the average daily airfare from January 1st until June 21st. The average price has been calculated based on our daily bookings across all sectors.

• High: Rs. 4,409 on February 14th (Special Valentine's day pricing, perhaps?)
• Low: Rs. 2,711 on January 30th
• Average: Rs. 3,846

February and March were the months with the wildest fluctuations in pricing, with relatively steady pricing in April and May. June was again witness to large fluctuations.

The interesting thing here is that the price cuts don't last very long at all, so when the price falls, people should take advantage and book immediately.
