The 87-year-old passenger had asked to go to the toilet when the flight from Los Angeles to Heathrow was delayed on the tarmac for 90 minutes. A BA cabin crew member is alleged to have blocked the aisle to prevent the woman, Kocharik Tsamouzian, from leaving her seat, the Daily Mail reports.
Mrs Tsamouzian, who then wet herself, did not have a change of clothes and spent the rest of the flight in a distressed state, the paper said. BA said it was adhering to CAA rules that stipulate passengers must be seated with seatbelts on when the aircraft has started moving.
The CAA has been approached for a comment.
