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.
Singer Katy Perry ranked second among the celebrity homes most requested to see by visiting tourists.
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.
