The xONEx rule (and also found in many other RTWs and similar products) just means you cannot pay $ to upgrade single sectors - ie if you want that flight in paid first you need to buy AONEx not DONEx plus surcharge. There is nothing stopping you using miles or elite upgrade instruments to upgrade individual sectors.
