It was an AC bus, but AC is not working. Stuff said that the owner already aware of this problem. Don't understand still why he runs this bus. Worst service. I booked two sitter sit for me and my friend. Suddenly got a message on the morning of the journey that your Bus from Bangalore to Chennai (AC sleeper) is confirmed. I have to fight with them to get another sitter bus from Bangalore to Chennai. When I booked it was not mentioned by the travel agency that it's not a direct bus from Coorg to Chennai. Why they hide this information? and how could they change by sitting sit to a slipper class. I am traveling with with a girl. Without informing they are doing all this nonsense stuff. Very poor service and poor bus by SEABIRD from Coorg to Bangalore. Bangalore to Chennai bus was OK. Please don't travel with SEABIRD from Coorg to Bangalore, You can travel in local bus to Mysore then can take bus from Mysore to Bangalore. Local KSRTC buses are far far better then this bus. And I confirms after discussing with their local agents they are using same daily from Coorg to Bangalore. Please take some action against this bus authority.
