Flights into and out of the South Indian city of Chennai continue to be severely affected because of the heavy rains.
With the airport tarmac still remaining under water, the Airport Authority of India has ordered the Chennai International Airport to remain closed till December 6, 2015.
Chennai airport has been closed since December 1.
Indian-Americans with tickets to Chennai should contact their travel agent or airlines to reroute their tickets to neighboring cities like Bengaluru or Hyderabad.
Several hundred passengers have been stranded at the Chennai airport and local authorities are trying to evacuate them by buses.
But since the roads leading out of the airport have been damaged by the heavy rains, the evacuation of passengers is proving difficult.
Several international airlines including Singapore Airlines, Lufthansa, Air India, British Airways, Malaysia Airlines, Qatar Airways, Etihad Airways, and Emirates offer services to Chennai.
