New "Mad Men" season 7 teaser: "It's all up in the air"

A second teaser for the upcoming seventh season of "Mad Man" has been released -- and in typical "Mad Men" fashion, it offers few clues at what's to come.

Like the first teaser, which came out earlier this month, this one is set at an airport. Cast members are seen stepping out of a taxi, buying a ticket, sitting in a departure lounge, carrying a suitcase and, finally, a shot of Don Draper standing on the steps to a plane.

There's also lots of bright, colors and clothes that hearken towards the coming '70s (the show left off in 1968) and the sounds of "Let Go (Breakdown)" by British soul singer Alice Russell.

A tagline reads, "It's all up in the air."

"Mad Men" returns April 13 at 10 p.m. ET for the first of seven episodes. The second set of seven episodes will run in 2015.
