Please don't book this bus operator, bus quality ok, but sfaff behaviour was very bad, though you selected your seat while booking online, you will not get booked seat it will be given to who booked it offline because they charged more. When I raised the concern I was told to get down.
Also please book any tickets from red bus, they will just tell you "we are sorry sir we tried calling bus operator, unable to reach them we will raise the issue. Next day morning you will receive email saying (inconvenience regretted will take care next time it should not repeat) that'll Red bus never takes any responsibility this happed 3rd time to me where RedBus did not do anything. I stopped booking form RedBus,
Book on your own risk on RedBus
