Travel disruptions are expected to continue on Friday as Terminal 1 will remain closed, according to a tweet issued by the airport.

Inbound and outbound flights have been at one of the world's busiest airports.

Since Thursday, more than 130 flights have either been canceled or delayed, according to FlightAware.com.
