Dubai airport struggles to resume flights after heavy rains leave runways underwater | National [Video]

(CNN) — Dubai International Airport, one of the world’s busiest aviation hubs, remained in disarray Thursday after unprecedented heavy rain led to airliners having to negotiate flooded runways.

While check-ins for Emirates and Flydubai, the airport’s two main operators, had reopened, the airport warned that its Terminal 3 was experiencing high volumes of travelers as airlines tried to handle the backlog from cancellations and delays.
