The only way to assure your upgrade gets bonus PQM's, etc. (besides buying a premium cabin ticket in the first place) is to call and have your reservation reticketed into a premium fare code. (there's no change fee). If the amount quoted is equal or less than the TOD offer, have the agent do it. If it's more, then decide whether it's more important to have the additional PQM's or the other benefits (BG1, hard/soft product, etc.) at a less expensive price.
