Delhi’s airport is the Indira Gandhi International airport and is very well connected to cities across India and the world. There are regular flights to Delhi from Mumbai, Bangalore, Chennai, Hyderabad, Lucknow, Goa, Kolkata, Guwahati and international destinations as well. The airport is divided into two terminals, namely Terminal 1D and Terminal 3. Terminal 1 D is the domestic airport and is primarily used by low cost airlines such as Spice Jet, IndiGo and Go Air among others. Terminal 3 or T3 as it is commonly known, is the international terminal which is used by all international carriers operating to Delhi and full fare domestic airlines. A free shuttle service operates between both terminals every 20 minutes.
The Indira Gandhi International Airport is 22 kilometers away from the city centre. There are regular DTC (Delhi Transport Service) buses which operate regularly from outside the airport towards the city and the ISBT bus stand and the New Delhi Railway Station. The Delhi Airport Metro Express runs from the New Delhi Railway Station to Dwarka, crossing the airport along the way. The metro train service runs every 20 minutes and is a quick and convenient way to get to the city. You can also hire a pre-paid taxi from government registered counters at the airport, which would take you 40-50 minutes to get to the city centre depending on traffic.
Delhi is the headquarters of the Northern Railways and there are five major railway stations in Delhi, namely the The New Delhi Railway Station, Old Delhi Railway Station, Nizamuddin Railway Station, Anand Vihar Railway Terminal and Sarai Rohilla. The New Delhi Railway Station is one through which most trains arrive and depart from Delhi and is located in Paharganj, near Connaught Place. There is a pre-paid taxi booth outside the railway station and you can take a taxi from here to go further into the city.
The Delhi Metro line 2 also connects the New Delhi Railway Station to other parts of the city and is a convenient way to get into the city. There are also DTC buses (green and red coloured buses) which can take you into the city at a reasonable price. Apart from that you can also take auto rickshaws to places like Connuaght Place and Old Delhi. Though autos are supposed to go by the fare metre, many times they refuse to do so and it is best to ask a local how much the rough cost to a destination should be to make sure you are not cheated. You can also hop into a cycle rickshaw if you’re going to Connaught Place, though cycle richshaws are not allowed inside Connaught Place and you’ll be dropped slightly away from your destination.
