Does anybody know how PQP credit is calculated for award tickets with some flights operated by UA and some by partner airlines? I had an award trip to Europe with transatlantic segments on United and the rest on OS/LH. Booked in business, paid lots of miles. United correctly credited PQS only for the two UA operated segments. However, PQP credit is wrong. For one segment, no PQPs were credited, which is definitely a mistake. For the other one, the credit was less than 300 PQPs, which seems too low.

How does United allocates the points paid among UA and non-UA segments?
