The correct answer is Indira Gandhi International Airport
In September 2020, India's first corona-virus airport testing facility was launched at Delhi's Indira Gandhi International Airport.
The facility has been opened at the terminal-3 of the airport.
International passengers travelling without a valid COVID negative certificate can get tested for Covid-19.
Until the results are confirmed, passengers will be isolated at the waiting lounge or may opt to stay in a hotel.
In case of a positive result, passengers will be processed in line with applicable ICMR (Indian Council of Medical Research) protocols by the State authorities.
Delhi International Airport Limited (DIAL) is an operator of Indira Gandhi International Airport.
