Officials say Dubai airport, the Mideast's busiest, will undergo a major runway overhaul starting next month that will see more than a dozen airlines shift flights to another airport in the city.

Dubai Airports said Sunday that two runways at Dubai International Airport will be closed at alternate times during the project, which includes resurfacing one of the runways, lighting upgrades and construction of extra taxiways. The work begins May 1 and runs through July 20.

Fourteen airlines that currently fly out of the airport, including budget carrier FlyDubai, will temporarily move at least some flights to the alternate Dubai World Central airport during the project. Dubai's main carrier Emirates will not move any flights.

Dubai International ranks behind only London's Heathrow in terms of international passenger traffic handled.
