[article] Southwest Airlines Co., which now carries more domestic passengers than any other carrier, announced Monday that it will make its first foray into international service on July 1. The airline will begin with nonstop flights into Nassau, Bahamas; Montego Bay, Jamaica; and Aruba. By the end of 2014, it will also begin service to three Mexican destinations, Mexico City, Cancun and Cabo San Lucas, and to Punta Cana, Dominican Republic. But travelers out of Dallas Love Field need not get excited about flying nonstop to any international destinations. They’ll have to make at least one stop in the United States before they reach a non-U.S. airport out of Dallas. That’s because a change in the Wright amendment in 2006 prohibited nonstop international service from Love Field. That ban stays in place, even after the ban on flying nonstop to any U.S. destination expires Oct. 13. Southwest chairman and chief executive Gary Kelly drew an analogy between Southwest’s decision to begin its international flights in three cities and Southwest’s 1971 launch of service to three cities in Texas. Southwest is taking over the seven international destinations from AirTran Airways Inc., the subsidiary it acquired in May 2011.
