Never, ever again. AVOID
When we originally booked we chose our seats online. When we checked in we were told the seats we had booked were given to someone else. We were told we were sitting separately and only way we could sit together was to pay £240 for the emergency exit seats, (even though somebody would have had to sit here anyway). When we got to Bejing, the 5 1/2 hour flight to Bangkok was then in a Ryanair style flight and again we were sat apart. Will never use this airline again. Better to fly via the Middle East. Better aircraft, better transfer, better food, better customer experience.
