Just had a weird experience booking a trip with Avion points. Apparently, trips that don't end at the same city they started as are now redeemed at 1:1 instead of the regular redemption schedule. So I just added a final leg of my trip to connect the city I wanted to end up in to the city I started in (not planning to use this segment) and my redemption value dropped by some 16k points.

Seems wasteful and silly but it works fine. I just have to call the airline and let them know I won't need that last flight segment.

Hope this helps someone!
