this question might fit under a copy of discussion - thoughts/advice appreciated:

upcoming DEN-OGG flight:
M fare ticket
PZ0/PN0/etc
27/32 booked in first
1k applying PP - current 3rd on list (behind 2 pass with similar last name)

not sure where I would be without PP
do I monitor for PZ>0 .... might that happen? just check the app frequently - and if I find it, quickly cancel my PP and call for an instant upgrade
- would I still get or be eligible for an instant upgrade - and not get charged for PP - if that becomes an option?

- right now, have an E+ window with a middle seat open and what appears to be a lot of capacity - including a bunch of E+ windows and aisle available - so, dont mind that option...hence not worth the SDU and buy up costs....

..or just let it ride and if it costs 20 PP... then that might be 20 PP that I dont have to worry about expiring next year?
