Kristin Chenoweth is a passionate animal advocate, and she recently hosted the 2012 American Humane Association Hero Dog Awards honoring the nation's most courageous canines. She also started an organization called Maddie's Corner to connect people and animals, in honor of her Maltese, Madeline. 

But Kristin had a bad human experience on Tuesday when she and Maddie tried to board a flight from Dallas to L.A. (Side note: Was she coming back from visiting Jake Pavelka for his birthday?)

According to TMZ, an American Airlines flight attendant supervisor reportedly told Kristin she didn't have the right paperwork for Maddie to board as a service dog. Kristin protested, but the supervisor supposedly "erupted" in front of everyone, and Kristin was so upset by the scolding she started crying. Ultimately the airline realized Kristin was OK to bring her service dog on the plane, but KChen was not happy. She later tweeted, "American Airlines: Dallas flight attnt supervisor Ms. Kidwell. Abuse not okay. #tripfromhell."

TMZ talked to an American Airlines rep, who said they offered Kristin their apologies and even refunded the $125 cabin pet charge when they realized the error. “We hope she will consider flying American again in the future."

They’re probably most upset that this happened to a famous person whose tweets have a wide reach. It’s possible this was just a big misunderstanding and the supervisor didn’t "abuse" Kristin or do anything more than airline staff usually do when they are in official policy mode. It's only natural that they would question why Kristin's little Maltese would be considered a service dog. Then again, curt behavior has become official policy mode at many airports, so perhaps this will be a wake-up call in how to treat people. Still, if this happened to The Rest Of Us we’d probably be lucky to just get a half-hearted apology.
