I am writing on behalf of a passenger. Incident occurred on the plane when passenger was sitting and had a celo fall on her head while she was already seated in her seat. It was determined that she go to hospital to get checked out and was told by the manager not worry, that they would look after her. After medically cleared, was informed she had to find her own way back to the airport and get a hotel. Nursing staff helped deal with situation and eventually American Airlines relunctantly paid for a hotel, but refused to pay for taxi back to the airport. The hospital ended up paying for taxi back to the airport. Passenger was upset as she was reassured by the manager and that would look after her and they did not carry out their word. American Airlines should be held accountable as this incident occurred on their watch and maybe they need to have stricter rules as to what can be a carry on item or they need to be stored somewhere else on the plane to avoid injures occurring to their passengers.
