The 60-foot, articulated, compressed natural gas buses will provide around-the-clock service at BWI.
“These new buses will offer our travellers the highest level of comfort and service,” said BWI's executive director, Ricky Smith.
“As our passenger traffic grows, the buses will also provide more capacity to serve our rental car customers.”
The sleek bus design features the distinctive colours of the Maryland state flag.
The new buses, which are manufactured by New Flyer of America, Inc, offer many important customer service amenities, including: WiFi, USB charging ports, infotainment screens, plush seats, three sets of wide doors and large windows.
The articulated buses provide about a 50 percent increase in capacity over the older rental car shuttle fleet.
In December 2016, the Maryland Board of Public Works approved the contract to procure the 20 buses. The $15 million purchase is funded through the Customer Facility Charge (CFC) fee on airport rental car transactions.
About half of the new buses will be in service this week. The remaining buses will be delivered to the airport and put into service before the end of the year.
The new buses will replace a fleet of 40-foot, transit-style rental car shuttle buses that were manufactured in 2004.
