Update: The internet speed is horrific over the Taktamakan Desert. For a night flight, that’s the location when most people wake up from their naps. I could barely load FT to make this post or send a text to catch up with my friends.
If this is the free WiFi given to business passengers and DMs, it is not much better than the free texting package on BA. At the moment, it is not worth 20 USD to me.
