So, where can the super fast ViaSat Ka Band WiFi be found? The only article I can find that mentions it with specifics lists only 3 tail numbers, but that was back in February.
Specifically,
this article states "Update: As of today, United's 737-900s with tail numbers N75425, N75435 and N38451 are equipped with ViaSat WiFi."
Has anyone actually used this new high-speed WiFi? Does it work well? How can you tell which planes have it?
