Is it true that China Eastern Airlines points are exchanged for SMS?

It's true. There are quite a few things that can be redeemed for China Eastern's membership points, not only air tickets and upgrades, but also things in China Eastern Mall in official website, such as mobile phones, beauty cosmetics, electrical appliances, department stores, mothers and babies, etc. It's true that points are exchanged for text messages. China Eastern Airlines is a wholly state-owned company directly under the central government and one of the three major state-owned backbone aviation enterprises supervised by the State Council SASAC.
