The new flights also include four new seasonal flights connecting Jaisalmer, the 'Golden City' of India, with Delhi and Ahmedabad, the airline said in a release.
Under the Udan scheme, financial incentives from the Centre, state governments and airport operators are extended to selected airlines to encourage operations.
The flight, according to an official statement from Air India on Thursday, will fulfil a long-standing demand for a direct air-link between the two major cities.
"A UV (ultraviolet) robotic device fitted with UV disinfection lamping system was engaged by the airline today at Delhi airport to disinfect its Boeing 737-800 aircraft," Air India Express said in a release on Thursday.
The airline will operate a Boeing 787-9 Dreamliner aircraft between the Indira Gandhi International Airport in Delhi and its hometown hub at the O'Hare International Airport in Chicago.
