lso, ignore the explanation of the driver for additional payment. There is no practice of tipping taxi drivers anywhere in India. When you reach your destination, take your baggage first, then give the driver the receipt and walk away without further discussion.
There is a minor problem with this system. As there is a checkpoint manned by the traffic police just as your taxi moves away from the airport, you will have to give the receipt to the driver, who will hand it over to the police, who will record the taxi number. Make sure that you get the receipt back from the driver only after you have safely reached your destination.
When leaving Delhi from the international terminal, you should show up three hours before your flight is scheduled as security is tight. For domestic flights two hours should be enough. While sometimes time-consuming, the process is smooth, and the new terminal's shops and restaurants are sensibly located at the gate area, not before security. However, if you wish to change Rupees back into foreign currency, you must do this before clearing security.
During the winter (Dec-Jan), Delhi often experiences dense fog and visibility is reduced considerably, making it difficult for flights to land and take off. Both international and domestic flights are often diverted or cancelled, so plan accordingly and allow for one or two days for possible delays.
