4G,
I am planning the commute from Calgary. The flight choices are somewhat limited on ANA, but they worked very well for me. I went through SFO for my interview, the connections in LAX work quite good as well. I hope to commute on Air Canada through Vancouver if that works, it saves about 3 hours on the total transit time. Parc has said that they prefer you to use ANA if you can, but are open and flexible to other options once you are on the line.
I was lucky enough to be upgraded to business on the flight home, and that made all the difference in the world. Arrived home rested, relaxed and ready to go. The service on ANA is second to none!
I have also read that ANA is considering flights to Canada: YVR, YYZ???
Either way, I am fully commited when (and if) the call comes with a ground school date!
Have you been through the process already?
Good luck on the decision 4G!
