Flew Cathay Dragon HKG to Busan yesterday with my Mac, hoping to watch some of the GOT episodes currently playing. Except that my Mac would not play anything (neither safari nor Chrome); even though I downloaded the "plugin" that the episodes demanded. The staff said "oh you have to download an app before boarding if you have an iPhone". I said it's not an iPhone, it's a computer and the laptop instructions say nothing about downloading stuff before boarding. Anyway it was a 3 hour flight so really irritating. Does anyone know if this is a "rule" on Studio KA or what?
