So now, not only do we need to search for PZ space, we have to compare how much PP the upgrade will cost. Will UA show the PP cost prior to booking? Or will it be dumb and force everyone to book and then reveal its upgrade cost?
And will that mean different routes will have different PZ costs? So flying ATL-ORD-FRA with PZ1 may cost more than ATL-IAD-FRA with PZ9?
