The Las Vegas airport offers a 24-hour fitness center. Terminals in Detroit and Newark, N.J., boast spas. You can visit a dentist at New York's John F. Kennedy Airport, get glasses repaired at the Cincinnati airport, choose among three barbershops in Dallas-Fort Worth terminals, pause at a nail salon in Boston's Logan Airport and book massage treatments at a Nashville airport bar. Kiosks rent digital video disc players and movies to delayed passengers. Some properties include swimming pools, or even coordinate with adjacent golf courses, placing pro shops in terminals.
Airports serve as branch offices, too.
Used to be, only travelers with memberships in an airline's private club had easy online access while awaiting flights. Today, computer centers in public areas do a booming business. Shops are no longer predictably routine, instead taking on the personality of a city or its famous residents. Also evolving are airport restaurants. You don't have to venture downtown to savor lobster in Boston, crab cakes in Baltimore or fish tacos in San Diego.
