A new metro line connecting Indira Gandhi airport in Delhi with the New Delhi metro and railway station is now open, cutting the 23 km journey time to just 20 minutes.
By road, the trip takes between 30 and 45 minutes at quiet times -- but Delhi's notorious traffic can double the journey time at rush hour.
Ticket prices for the new metro link are a bargain at 80 rupees (A$1.75). Trains run every 20 minutes between 0600 and 2200.
At the airport, the metro stops at the new Terminal 3, which opened in July 2010 to ease congestion at South Asia's busiest airport.
In Central Delhi, passengers can change to the Yellow Line or onto Indian Railways trains at New Delhi station.
The metro line also stops at Shivaji Stadium, just to the southwest of the main New Delhi terminus.
Stops at Dhaula Kuan and Delhi Aerocity are planned to open in March, while an interchange to the Blue Line at Dwarka Sector 21 near the airport opened last week.
All stations on the line have been built to be accessible for disabled people -- which also means that travellers with rolling luggage should find them easy to navigate.
