Tx WineCountryUA. It's a good insight, and it indeed makes sense, however it triggers some extra questions...
This means that when UA has changed it's partner earnings recently they have to do this in agreement with their partners. I would suppose, as you describe it, that it will rather be the partners that decide on the mileage earnings. Why then did the mileage earnings change at the moment UA implemented it's new structure if it's mostly driven by the partners.
