By plane
Jaipur Airport IATA: JAI, ICAO: VIJP is situated in the satellite town of Sanganer and offers sporadic chartered service to London and Dublin. Flights to Singapore and Bangkok are available via Delhi. Direct flights to Sharjah, Muscat and Dubai are also available.
Jaipur also has daily domestic air links with many Indian cities such as Jodhpur, Udaipur, Aurangabad, Delhi, Hyderabad, Kolkata, Goa, Chennai, Ahmedabad, Bangalore, Mumbai, Pune and Indore.
One plus point for those flying out of Delhi is that the Delhi airport is close to the highway, so you could reach the airport without entering the city.
