Data released Wednesday showed the airport marked its best first half of the year and 12-month period in its history.

BWI chief executive Paul Wiedefeld says 10.9 million travelers used the airport during the first half of the year, setting it on a path to exceed 22.5 million passengers this year. The airport has set monthly records in 13 of the past 14 months.

In June, BWI also set an all-time record for the month with more than 2.1 million passengers. June cargo shipments also grew to more than 19.7 million pounds, an increase of 9 percent over June 2010.

Wiedefeld says BWI has benefited from Maryland's relatively strong economy and the military's base relocation program.
