- USA 3000 and US Airways began service from BWI to Bermuda.
- BWI serves as first of 115 U.S. international airports using the outgoing US-VISIT process. Designed and implemented by the U.S. Department of Homeland Security, the United States Visitor and Immigrant Status Indicator Technology process is used to confirm the identity of travelers entering and exiting the U.S. via air travel. All international airports perform incoming US-VISIT functions; BWI is test airport for the outgoing system.
- Free Arrival Waiting Area, also known as the Cell Phone Lot opens at BWI. The lot provides drivers with about 50 short-term parking spaces as they await cell phone contact from arriving travelers. The lot is an alternative that saves drivers time, while limiting traffic in front of the Airport terminal during construction.
- BWI’s second skywalk opens to the public, connecting the terminal (at Concourse B) to Level 6 of the Hourly Garage. This is the second of three skywalks to be completed and opened to the public. The skywalks provide quick, safe and convenient access to and from the main terminal.
- Tripling the number of parking spaces available close to the main terminal building, BWI opened the new Daily Garage. Located at MD 170 (Aviation Blvd) and Elm Road, the garage offers 8,400 spaces and was constructed with “Smart Park” technology. “Smart Park” is an automated guidance system intended to make finding a space quick and easy. At the time of opening, BWI was the only East Coast airport to mount ultrasonic sensors over each parking space to monitor the availability of spaces.
