Severe flooding in the Indian state of Kerala has forced Cochin International airport in to close until 14:00 local time on 26 August.
"This is done to minimise the inconvenience to passengers and as a precautionary measure to ensure operational safety," the airport states.
The Directorate General of Civil Aviation says it is monitoring the situation and has advised domestic carriers to reroute their Cochin flights to Trivandrum and Calicut.
The regulator has also advised carriers to "ensure that airfares to and from Trivandrum and Calicut airports... are kept at optimal level proportionate to sector distance." It has taken the action of capping fares on the Delhi-Trivandrum route at Rs10,000 ($143).
Most that foreign airlines have re-routed their Cochin flights to Trivandrum, or have temporarily suspended their services.
Media reports say that over 100 people have been killed in the floods, which have been caused by heavy rains.
