General sleeper for shorter distances up to 1000 will still be cheaper then bus fares. even they are raised 100% by 2020. The travel I'll also be less in many sectors in north east and western India. Even 3ac I'll be cheaper if they are raised by 50% as crude prices may raise to $80 by 2020 and airlines cannot survive long with rock bottom fares. Even now the margins are under pressure due to low fares and competition.
