A record number of passengers flew through Baltimore-Washington International Marshall Airport in 2016, Gov. Larry Hogan (R) announced Tuesday.

In all, 25.1 million passengers traveled through BWI. That beat the previous record of 23.8 million set in 2015.

“This record-setting growth reflects the importance of BWI Marshall Airport to the Baltimore-Washington region and our state,” Hogan said in a news release announcing the milestone.  “Our administration is committed to the continued success of BWI Marshall and its role as a vital transportation and economic development resource.”

The airport also broke its previous record for international passengers with more than 1.2 million passengers in 2016. Last year also was the second-straight year that more than one million international passengers flew through BWI.

“New airlines and service to new domestic and international destinations have led to steady growth and new records,” said Ricky Smith, the airport’s chief executive officer.  “We continue to emphasize customer service, affordable airline fares, and an efficient travel experience for our passengers.  The new passenger record is the highlight of an outstanding year.”

Just a few months ago, Hogan, along with business and transportation leaders across the region, celebrated the opening of the D/E connector, a new security checkpoint for domestic and international travelers at the airport.

Officials at Reagan National and Dulles International airports are expected to release passenger traffic statistics for 2016 later this month.
