Ugh I booked YQM-YHZ-YUL-YOW-YHZ, all in G.
There is now YQM-YOW G fare, so it split it to YQM-YUL and YUL-YHZ.
I could upfare to V for free. I'm trying to figure out if I can upfare to P for free or minimal cost
Playing around with ITA and EF... sigh.
However, my final PNR has 6 segments on 2-cabin aircraft, and 2 on BEH. One of the segments is YYZ-SFO, to put into perspective the value of doing this. I can upfare the entire thing to P class for $244 CAD per person.
