Airport Check-in: New trams on track for Las Vegas McCarran

— -- Travelers who fly from Las Vegas McCarran's D Concourse will need to arrive earlier due to a construction project that will interrupt its tram service for several weeks.

Passengers usually use a pair of parallel trams to get to the D Concourse. But for much of February, only the south trams will be in service while workers replace the north trams. Once the north trams have been replaced, both sets of trams will resume their regular schedule for about a month before the south trams are taken offline for replacement beginning mid-spring.

The airport advises passengers traveling in peak hours to arrive 30 minutes earlier. Airlines based at D Concourse include AirTran, Alaska, Allegiant, American, Continental, Delta, Frontier, Horizon Air, JetBlue, Northwest, SkyWest, Sun Country, Spirit, United and Virgin America.

•Lufthansa will open later this month at Frankfurt International a new lounge that caters to first-class passengers and its most elite category of frequent fliers.

The new lounge, in Concourse B of Terminal 1, will primarily benefit U.S. and other transfer passengers who previously had to exit the airport to use the airline's First Class Terminal.

The lounge will provide many of the services offered at the First Class Terminal — a dedicated security clearance area, computer stations, food and drinks, shower facilities and day beds. The 13,100-square-foot lounge will also feature a spa.

•American Airlines has opened an Admirals Club lounge at Washington Dulles International, the final step in its relocation to Terminal B. Located near Gate 63, the 3,000-square-foot lounge offers business center tools, food and drinks, and assistance with boarding passes, reservations and upgrades. American shifted its operations from Terminal D in June 2008.

•To reduce noise in surrounding neighborhoods, Burbank's Bob Hope Airport is seeking federal approval for a ban on late-night flights. If approved by the Federal Aviation Administration, the airport would prohibit cargo and passenger carriers from landing between 10 p.m. and 7 a.m.
