I've looked at some of the old threads on flight passes -- I need to do a few YYJ-NRTs. Given some changes, I'm not sure the old comments are still relevant (but hey, I could be wrong).

The passes seem like a good price, but they only book into Tango, which means no upgrades ever. Also they depend on the availability of N.

I'm torn. I'd love to get a few opinions from flight pass veterans.

Thanks.
