A woman is suing American Airlines for more than $75,000 after an April 17 incident in which she claims a flight attendant shouted abuse and called the police on her because she was travelling with an emotional support dog in the cabin. At one point, Avigail Diveroli of Miami, Florida claims the flight attendant even locked the small dog in a lavatory for an hour and slammed a toilet door against the dog’s cage. Diveroli had booked a Business Class ticket to fly from Miami to Los Angeles, along with her husband and disabled 87-year old grandfather. Because she suffers from severe anxiety, Diveroli requested permission to have her Emotional Support Animal-registered dog, Simba, with her in the dog. According to court papers filed in the U.S. District Court for the Southern District of Florida, the airline approved Simba as an onboard ESA and Diveroli twice called American Airlines to confirm the dog could travel with her in the cabin.
