US Department of Transport: BTS Releases July 2007 Airline Traffic Data; U.S Airlines Carried Record Number of Passengers in July

U.S. airlines carried 72.2 million scheduled domestic and international passengers on their systems in July, a record high for a single month and 2.2 percent more than the previous record of 70.6 million in July 2005.


America West Airlines and US Airways reported traffic data separately in July because the carriers held two operating certificates despite their merged business operations. They are now operating under a single certificate and will begin reporting data jointly later this year.
