Check in where you check out

Starting next month, guests at the Hyatt Hotels in Boston and Cambridge will be able to check luggage and get airline boarding passes from all US airlines in the hotel lobby for $10 a person up to 24 hours before a flight. Hyatts in Miami, Orlando, Tampa, and Seattle will get the service by December.

Plans for direct one-stop service from Logan to China, announced by Mayor Thomas M. Menino in January, still haven't jelled, but a dogfight is breaking out for nonstop service to Shanghai. Continental Airlines last week proposed a daily flight from Newark Liberty International next year on 283-seat Boeing 777s, joining rivals competing for the one new Shanghai flight US officials will approve next year. The others are American from Dallas/Fort Worth, Northwest from Detroit, and United from Dulles International outside Washington, D.C.

Hoping to debunk an urban myth, American Hotel & Lodging Association president Joe McInerney recently issued a statement declaring there is no truth to rumors that hotel key cards contain guests' credit card number, e-mail address, or home address. Nor is there a universal master key that can disable electronic locks .

United Airlines last week unveiled its first fully automated ``dual-end" jet bridge, which speeds boarding and unboarding by letting passengers use doors at both ends of narrow-body planes. An extension goes over the jet's wing to reach the rear door. Denver International's B15 is the first of five Denver gates getting the bridges this year. Spokeswoman Megan McCarthy says United will decide next year whether to add them at Logan International Airport in Boston or in other US cities.
