Did you fly in or out of Baltimore-Washington International Marshall Airport over the summer? If so, you helped the airport set a record for passengers.

BWI broke a record for passenger traffic in a single month when more than 2.2 million travelers used the airport in July, officials announced Tuesday.

The 2,222,329 passengers flying through BWI that month helped break a record that was set a year earlier, when 2,205,035 riders used the airport in July 2011. And that number broke a record set in July 2010 when 2,120,517 people flew through BWI. In other words, July is a busy month at BWI.

More than 1.2 million passengers flew on Southwest Airlines, the largest airline servicing the airport.

BWI also set a record for passenger traffic last year, with more than 22 million people using the airport.
