Little Overlap in American, US Airways Routes

In the jigsaw puzzle of airline routes, American and US Airways are two pieces that fit together almost perfectly. Of the 50 busiest domestic routes, the two carriers compete directly on only one: Los Angeles to Phoenix, according to OAG, a company that tracks airline routes and schedules. And on hundreds of less traveled routes, they only overlap a dozen times, mostly between their hub cities. The combined airline will offer more than 6,700 daily flights to 336 destinations in 56 countries. The complementary nature of the markets they serve should help the airlines avoid any major hurdles with antitrust regulators, industry experts say. And it will serve the merged company especially well in today’s airline business, which is all about scale.

American has a strong presence in Dallas/Fort Worth, Miami, Los Angeles, Chicago and New York. It is also the dominant U.S. player in Latin America. American also has a lock on flights into London Heathrow, one of the world’s key financial capitals. US Airways is the principal carrier in Philadelphia, Charlotte, Phoenix and Washington, D.C. It also has routes into key European cities that American doesn’t directly serve, such as Amsterdam and Brussels. American would also gain U.S. Airways’ lucrative shuttle service between New York, Boston and Washington D.C.
