http://www.kctv5.com/clip/13315172/...orced-to-pee-in-cup-on-united-flight-she-says A passenger claims that flight attendants (on a Mesa Airlines) wouldn’t let her get up to use the washroom after the pilot turned on the fasten seatbelt sign. Apparently she has an overactive bladder and either needs to go to use the restroom or pee in a cup. She was handed a cup by the flight attendants. Actually, she filled up 2 cups. Going public with this because UA customer service has not responded to her satisfaction.
