Qatar Airways sold my wife a preferred seat but did not allow her to take the seat. Despite all the purchase documents presented on the flight, the flight attendant forced her to the back of the plane on a seat that did not recline. She is 64 and is suffering from arthritis. We are planning to seek legal advice and submit an official legal complaint for the physical and emotional mistreatment of a paid customer. It is almost impossible to communicate with Qatar Airways authorities—the worst ever experience. It happened on a January 10 flight from Montreal to Doha.
