Woman forced to pee in cup on United flight from Houston to Kansas, she says

United Airlines could be under fire again for the quality of its customer service in friendly skies.

Nicole Harper, who was on a flight from Houston to Kansas, said she had to go to the restroom. When she tried to go, she was told to go back to her seat, she said.

"I said 'I'm going to need to use the restroom or I'm going to need a cup,'" Harper said. " (They) didn't understand that I don't have any control over the situation."

Harper said she's lived with an overactive bladder her entire life.

She claims she told the flight attendant about the issue, and when she said she would either need to go to the restroom or be given a cup, the flight attendant gave her a cup.

Harper filed a complaint with United Airlines and the Department of Transportation.

United Airlines released the following statement:

"Customer safety is always our first priority. Initial reports from our flight attendants indicate that Ms. Harper attempted to visit the lavatory on final descent and was instructed to remain seated with the seat belt fastened per FAA regulations. The situation as described by Ms. Harper and our employees is upsetting for all involved. We have reached out to Ms. Harper and our flying partner Mesa Airlines to better understand what occurred."

Harper received  a lot of support after she posted about the incident on social media.
