Delta Air Lines may be ready to adopt a new slogan.
Delta has filed for trademark protection with the U.S. Patent and Trademark Office for what sounds like the airline's newest motto: "The World's Most Trusted Airline."
Delta has used several slogans over its 85-year history, including "We love to fly, and it shows," and, more recently, "Keep Climbing."
A Delta spokesman declined to comment. Industry experts say airlines often seek trademark protection for slogans simply to prevent competitors from using it.
Already taken: United Airlines' "Fly the friendly skies" and American Airlines' "the new American is arriving," adopted after the merger with US Airways last year.
