16 asymptomatic passengers on seven different flights, including 13 who travelled by IndiGo, have tested positive for COVID-19 since the resumption of domestic air services on Monday, according to airlines data.
Two of the three asymptomatic passengers who tested positive for the infection had travelled by Spicejet while one took a flight of the Air India subsidiary Alliance Air.
The Karnataka government, meanwhile, said on Thursday it has requested the Civil Aviation ministry to reduce the number of flights originating from Maharashtra, Gujarat, Tamil Nadu, Madhya Pradesh and Rajasthan in view of the high number of COVID-19 cases in the state, hours after a minister said it has "suspended" air travel from these states.
Seeking to clarify his statement, Law and Parliamentary Affairs Minister JC Madhuswamy maintained that Karnataka has not sought a ban on flights from the five states as reported in some sections of the media.
Karnataka has appealed to the Civil Aviation Ministry to take steps to lessen the air traffic to the state, with the "sacred intention" that there may not be adequate quarantine facilities, if there is a huge turnout in a short span of time, he said in a press release issued by the state information department.
West Bengal, which allowed resumption of domestic air services from Thursday, and Maharashtra are among the states who have requested the centre for limited flight operations in the wake of the COVID-19 pandemic.
