@username (OP)
can you add this link to the OP? It shows the 77A routes (with Wi-Fi)
http://sky-wifi.evaair.com/#flight
Looks like only these routes for now
TPE-LAX BR 11/12
TPE-JFK BR 31/32 (starting July 3 all flights will be 77A)
I'd choose YYZ-JFK-TPE instead of YYZ-TPE just because of wi-fi
in Y on Aeroplan though @@
