I have travelled a lot via Volvo but the UPRTC volvo between Delhi and Agra totally surprised me and in a good way. The bus starts from Sarai Kale khan to ISBT, Agra. Apart from good leg space what actually is good is the wi-fi in the bus. They have a tie up with pressplay and this app is accessible in the bus via their own wi-fi. The library has music, movies and some shows. Never a bus ride was so good.
