I am. I've flown them a number of times. Air China is better by a country mile.
Koryo haha be real
China Eastern, China Southern, Koryo, Jet Airways, Aeroflot (because of Moscow Sheremetyevo and how awful they are are anything resembling comfortable transit experience), Ryanair, Easyjet. Even BA on some of their older aircraft are worse than Air China for comfort.
Reservation now includes 2 checked in bags per person. When I booked last year it was only 1. May email them to clarify.
Great post, thanks
