Your survey had taken in to account only the major established players in the Indian market today. But Air Deccan with its 500/- and 1000/- ticket is going to play another reliance mobile in the air travel sector. Even today when I browsed their website, airdeccan.net, DEL BOM DEL is approx 3200/- including taxes, if you book now for MArch 2005.A child ticket is 60% of this fare. Who would like to travel in trains now if one can fix there travel itinery two to three months in advance. Ideal for householders and students.
