Delhi has three airports but only the domestic and international terminals of the Indira Gandhi International Airport operate commercial flights. Delhi is India's major point for international flights with almost all leading international airlines operating in and out of Indira Gandhi International Airport, Delhi. Domestic flights from Delhi connects all major destinations of India and one can find readily available local airlines operating in and out of the domestic airport. From the city center the domestic airport of Delhi is roughly about 7 km away and the Delhi international airport is 11 km. The third airport of Delhi located next to the Safdarjung Tomb, unsurprisingly also called Safdarjung Airport, has no commercial operations and operates only as a flying club.

India's rail network is the largest in the world and Delhi's three major railway stations at New Delhi, Old Delhi, and Nizamuddin are connected to all major rail routes of the country. The New Delhi Railway Station is located half a kilometer from Connaught Place and the budget hotels center of New Delhi is just a stone throw away. Long-distance trains heads to all corners of the country from here. Old Delhi Railway Station is located near the heart of old Delhi, Chandni Chowk. Long-distance trains run from here to major destinations of India. The Nizamuddin Railway Station is located near the holy shrine of Hazarat Nizamuddin. This is a major railhead for trains connecting the western and southern states of India. And the Delhi Cantonment Railway Station at the Delhi Cantonment area is the starting point for some of the luxury trains of India such as the Palace-on-Wheels, Fairy Queen and Royal Orient Express.

Delhi is well connected to all the major cities of India by a network of highways and roads. There are three Inter State Bus Terminals (ISBT) at Kashmere Gate, Sarai Kale Khan and Anand Vihar, as well as many starting points in and around the city, from which various state-managed and privately run transport facilities operate air-conditioned, deluxe and ordinary coaches. Popular bus routes head into various destinations of Rajasthan, Haryana, Punjab, Uttar Pradesh, hill stations of Himachal Pradesh and Uttaranchal (click to see road distance guides/maps from Delhi).

There are various options available for city travel in Delhi. Delhi University Corporation (DTC) runs a large fleet of buses covering all areas of the city and is the cheapest mode of transport. There are also private city bus operators, auto-rickshaws and cycle- rickshaws for Delhi city travel. Tourist taxis ply interstate while the yellow and black taxis can be used to commute anywhere within the city and are safe but relatively expensive. Luxurious special tourist buses are also available with packaged tours to all the tourist attractions in Delhi. Delhi Metro railway is the most recent addition to Delhi's transportation options and is a convenient and efficient mode of transport connecting all major places within the city.
