In this Sunday, Feb. 10, 2013, photo a laborer cleans a window at the new Concourse A of the Dubai airport in Dubai, United Arab Emirates. For generations, international fliers have stopped over in London, Paris and Amsterdam. Now, they increasingly switch planes in Dubai, Doha and Abu Dhabi, making this region the new crossroads of global travel. The switch is driven by both the airports and airlines, all backed by governments that see aviation as the way to make their countries bigger players in the global economy. (AP Photo/Kamran Jebreili)
