I did a search on FT and on the Goog for a generic thread for Air Canada Premium Economy.
There isn't one. Most threads are about seats, prices, upgrade ability or PE as relates to Aeroplan.
So I'm posting this here and the Mod can move as he sees fit.
For those of us who buy PE for TPACs for example, and for those of us who have been buying and flying it since the launch of the B788s in 2014, we know what we've paid, we know where some routes have interesting pricing and of course, on routes we fly often in any cabin or on any fare class, we tend to know the range of pricing for seats on those routes.
I noticed this on AC's front page today.
I found this interesting but also to be expected. Still, just sharing.
