Interesting news from AY.
http://www.futuretravelexperience.co...i-fi-in-a320s/
Not only will all their (long-haul) A330s be fitted with KuBand Wifi by May next year, but they're planning to fit all their (short-haul) A320s with ViaSat Wifi (12Mbps) by the year after too.
Currently, access on their A350s is completely free to passengers in Business, and all
OWS and OWE cardholders. The plan for the A330s and A320s is the same.
Can't imagine BA being this generous - fully expect them to charge all passengers a la AA.
