Airport Update

Get a vision of the future at Dulles International : A full-scale prototype of the AeroTrain, which eventually will transport passengers between the terminal and concourses, is now located at the arrivals level of the main terminal. Travelers can board the prototype; the exhibit includes information on Dulles's past and the airport's improvement plan (and the method behind the current construction madness) . . . Baltimore Washington International Thurgood Marshall's "Park Happy" promotion just keeps on going; the coupons, available on the airport's Web site at http://www.bwiairport.com , are valid through Nov. 17. . . . Cancun International recently moved to streamline check-in procedures for passengers by acquiring 10 wireless stations that can be used to check in and print boarding passes . . . Liverpool John Lennon is now adorned with printed Lennon lyrics, an installation by artist Rigo 23 as part of the Liverpool Biennial International 06 (through Nov. 26). Colored-vinyl hangings bearing excerpts from "Give Peace a Chance," "Imagine" and other songs jazz up the check-in area, arrivals and airport facade . . . Singapore Changi's three-year upgrade of Terminal 2 was completed last month. Included in the refurbishment are 15 retail and 10 food and beverage locations, a foot reflexology spa and toilets with a view of the runway.
