Better buy up offer to PP or J if already purch E+?
Just thinking aloud. Got a couple long hauls coming up on both a 77W and 789, to and from SYD. Original purchase was award Y seating.
Are there any data points that buying up to E+ post-booking will either a) give you a better chance at a further buy up offer at check in to J or PP, or b) give you better buy up pricing to those cabins from E+?
Just curious.
