I have a 3-4 hour trip coming up (not sure how they determine the amount of purchasable PQP/miles), and have the following offers:
$175 - 7000 award miles (no PQP)
$250 - 10000 award miles (no PQP)
$660 - 7000 award miles and 500 PQP
$1220 - 10000 award miles and 1000 PQP
Mind you my wife, who does not have any status, pays slightly less for the miles/PQP combos $5 and $10 less respectively.
