Chennai International Airport is the third busiest in India (after Mumbai & Delhi). All international flights arrive at Anna Terminal, while the domestic flights arrive at Kamraj Terminal. The two terminals are on the same road and are 150 m (492 ft) away from each other.It is the second-largest cargo hub in the country, after Mumbai. Chennai is well connected to London, Frankfurt, Singapore, Malaysia, Middle east, New York, Hong Kong, etc. It is in the process of being upgraded to a world class airport with direct Metro rail connection to the city.
Chennai has one of Asia’s largest bus stations, Chennai Mofussil Bus Terminus (CMBT). Seven different state owned corporations drive buses to and from various destinations within South India. Connected to the Airport and the passenger train stations (Chennai Central and Egmore) by direct buses, it offers a cheap and spontaneous mode of travel. There are hourly buses for places like Tirupati, Pondicherry, Coimbatore,Tirunelveli. You will get the option of A/C or Non-A/C coaches for cities like Bangalore, Trivandrum, Hyderabad.
Several private players also operate buses between most southern destinations. During the weekends most buses are fully occupied and it’s better to reserve a ticket in advance. All buses terminate near Koyambedu but there are different stands for state owned (CMBT), and private buses (Omni bus terminus). Both these terminus are near each other, and it is better to tell your exact destination to the taxi/auto-rickshaw driver. Buses usually drop passengers at various points in the city before reaching the Terminus. Feel free to ask the driver or fellow passengers the closest drop-off point to your destination. Always ask for the ticket and carry it until the end of your journey. Conning is very rare.

Chennai is very well connected and to other parts of India by road. Five major national highways radiate outward towards Kolkata, Bengaluru, Tiruchy/Madurai,Tiruvallur, and Pondicherry. With the progress of the Golden Quadrilateral project, driving down from Bangalore is an option too. Indian drivers will have no problem fitting into the traffic but international drivers are strongly advised against driving in India.
