Many airlines would go into bankrupt (Delta, AirTran, United Airlines, and more...) Air transportation would depleat once everyone has an airplane. Trips to Hawaii would be easy. Airports won't become smaller, but only 8 airlines. Many other country named airports like Japan Airlines, American Airlines, U.S. Airways, EygptAir, and Czech Airlines, will become one airline known as SkyWorld Airlines. SkyWorld and 2 more airlines are apart of the Skyteam.
