"We were really excited to work with 'It's Always Sunny in Philadelphia,' as we're actually big fans of the show at Virgin America," an airline spokesperson tells TheWrap. "Some of the cast flies with us pretty often … so when the Philadelphia announcement was coming about, we thought it would be a fun tie-in for announcing the news, and the show and FX were terrific to work with and game to explore."

FX did not immediately respond to TheWrap's request for comment.
