Today I put together an itinerary via multi-citi and using GPU's for the available flights. When complete it used additional GPU's then in the past. So there were 6 legs and it calculated 12 GPU's for 2 people.

I called in and the nice lady I talked to did the same routing and it asked her for the 12 GPU's and she overrode it. She brought up the new mileage rules but said this shouldn't happen for revenue seats.

I did multi-city because when I put in the roundtrip with the same legs it said there was no R space but when done individually there was. The legs searched via mult-city or roundtrip were the same exact flights.

YMMV when getting customer service 1K to override the requested GPU's.
