Low-cost carrier FlyDubai has apologised for refusing to allow a blind American passenger to fly because of his disability, reported AP. Zuhair Mahmoud says he was told by FlyDubai airline staff members that the carrier's policies did not allow blind travellers to fly unless accompanied by someone else. The airline's CEO Ghaith al-Ghaith said the incident never should have happened and that the airline doesn't discriminate against passengers with special needs. He says the airline plans a full investigation and is sorry for the incident. AP reports that the 37-year-old Mahmoud, of Arlington, Virginia, is staying with family in Dubai until he can catch another flight out to Jordan before heading back to the US.
