The DGCA has banned spot pricing by private carriers till the time the crisis caused by striking Air India pilots is not resolved.
DGCA chief EK Bharat Bhushan met senior executives of private airlines on Monday and directed them to stick to the fares that airlines advertise and submit to the regulator at the beginning of each month.
Spot pricing is fare charged for bookings a couple hours prior to departure.
The pilot strike has grounded AI's domestic operations with reports of exorbitant fares being charged by private airlines for last minute bookings.
"No spot fares would be charged till the AI crisis gets resolved," Bhushan said.
The regulator has also asked private carriers to file revised schedules for slot allocation.
