MAD-HKG-PVG rt, was booked in E and the upgrade bid was 1013eur for MAD-HKG, called in and they offered 391eur total to upgrade to I class for MAD-HKG-PVG altogether....inventory is I9 for both flights at <48hrs before departure.
Does the call center's upgrade price adjust (downwards) as inventory remain high and time to departure decreases?
If flight is stll I9 at check-in at MAD would the counter offer even an even lower price?
