I plan on doing YVR in the summer. JFK is my home airport. So not sure to do on the way back 37.5k BA or maybe 62.5k AA to LHR with SO in JFK, since I'm planning to go Europe in the winter. But its only worth it for new 77W and availability looks close to done right now.
I'm not booking yet, but the question is will 77W in F open later on OR maybe just book 55K in J OR just with BA instead.
Decisions,Decisions,Decisions
ETA: Just checked AA and it looks like AA is showing availability on their new 777-300 in F
