Airplanes taxi at the Sao Paulo International airport, which is under renovation, in Guarulhos, Brazil, Tuesday, May 20, 2014. The chronic delays in airport renovations have matched those in stadium construction, and officials have acknowledged for a while that visitors will be using unfinished airport facilities. Brazil is trying to assure World Cup tourists that they won't face problems at airports even though not all upgrades will be complete. (AP Photo/Andre Penner)
