UAL just matched my US Airways Gold Preferred to Premier Executive. When I got the acceptance email it stated, "To remain a Premier Executive member, you will need to fly 15,000 paid flight miles or 20 flight segments on qualifying flights* within that 90-day timeframe.".

Does that mean 15,000 miles regardless of class or fare purchased? For example, just purchased a flight to NRT in Y class so I will get 589 (IAD to ORD) and 6274 (ORD to NRT). With purchase of a Y class you get a 50% EQM bonus. Does that count towards my meeting the 15,000 paid flight miles? Also, I will have a return flight in C class...does the class of service bonus count?

Any help or guidance is much appreciated.
