That said, isn't the whole fleet eventually going this way? It's not just for Hawaii, but the old Gogo is so slow it's borderline useless anyway.
If you want to advertise things and get additional fares for it, then you need it to be universal on those routes. The first airline with WIFI to Hawaii will be rewarded for the situation.
