I travelled on a business trip from Coimbatore to Tirunelveli by ABT Omni AC bus. The service was very good. The bus started on time and though we were a bit late and not able to board at the origin, the staff kept us informed and also allowed us to board at a point on the way. The bus was very comfortable and well-maintained, the ride was smooth and we reached our destination on time. We took the same service on our return trip as well. We would definitely travel by ABT Travels again.
