I’m probably wrong. Never upgraded anywhere so never had to make the tough calls…
I look at the required and discretionary contingency fuel. Sometimes, even when it says "closest alternate is x, min cont fuel is 45 minutes" they only give you 25 minutes of required and 20 minutes of discretionary. I just add the discretionary into my min fuel. But I shouldn't have to do that.
