Here's my most recent experience:

Fare Breakdown
Airfare: 606.00 USD
Breakdown from Saudi site:
SFO-IAH-LHR (VKX4NCE) - flown Dec 13 290.50
LHR-ORD-SFO (VKX4NCE) - flown Jan 14 290.50
LON-SFO - flown Jan 14 25.00
U.S. Customs User Fee: 5.50
U.S. Immigration User Fee: 7.00
U.S. APHIS User Fee: 5.00
U.S. Federal Transportation Tax: 34.40
September 11th.Security Fee: 7.50
U.K. Air Passenger Duty: 107.00
U.K. Passenger Service Charge: 63.50
International Surcharge: 458.00
U.S. Passenger Facility Charge: 12.00
Per Person Total: 1305.90 USD
The SFO-IAH-LHR leg was flown in 2013, so I was curious as to the PQDs that would be apportioned for LHR-ORD-SFO - the airfare part is relatively simple to calculate given the $290.50 + $25.00 breakdown from the Saudi website, but I wasn't sure how the "International Surcharge" would be broken down. Given the routing was different on the outbound v. return, would they simply halve the surcharge or calculate it some other way?
Simply halving the surcharge would give me $544.5 PQDs ($290.5 + $25 + $229), but looking at my MP+ statement, I received the following PQDs:
LHR-ORD $357
ORD-SFO $199
Total: $556
.....so there seems to be some slight calculation ($11.50) in my favor
