Alrighty, introducing a Qantas Point and Status Credit multi segment calculator: https://qantas-point-calc.vercel.app/ !

I hope people find it useful, let me know if you find any bugs (I'm sure they exist!) or have any feature requests.

It should hopefully be self explanatory, and very similar to Qantas's official calculator. The big difference is that you can input multiple segments for an itinerary.

Here is some background/caveats:
1) This was built from someone who previously credited all his flights to British Airways. As a result, I have no first hand experience with earning on Qantas. Let's just say some of the rules were confusing.
2) The calculator works based on the Qantas and Partner earning tables as defined here, and here. With earning categories found here.
3) There are some notes on the bottom of the webpage for items not yet implemented
4) It's not mobile friendly yet
5) For Qantas and Jetstar, it supports fare earning categories (e.g. "Business Saver"), but for partner airline it requires the fare class (e.g. "i"). I see this as a feature so a user does not have to manually look up what earning category a partner's fare class maps to, but others might feel differently.
