Thanks for the info, I've managed to find the MMB page where it shows what TP I will earn and have used the Qantas site to see the fare codes. For an upcoming booking, MMB appears to be showing a higher value than I'm expecting - 480 compared to 340 calculated using the BA Tier Point Calculator. I think this may be because we've UUA'd to First - will we end up with the 480, or will it revert back to 340? It's a holiday booking so all will get doubled, and if it does end up being 480 that will take me over the 1,500 for the year, if it's the 340 I'll need to book another flight, so it would be helpful to know in advance (flights aren't until April).
