It was Troian Bellisario (Spencer)!
"We overbook our flights because you people don't show up and leave us with empty planes" the words just said to me by an @delta attendant," Troian tweeted on January 22.
Troian was understandably not happy. "1st of all 'you people?'" she tweeted. "And 2nd of all I've never missed a flight in my life-- how can airlines not care about their paying customers?!?"
We hear ya, Troian! Fortunately, it sounds like she and her boyfriend, Patrick J. Adams did get a seat on the plane.
