Got a bit tired of manually calculating the points from the Finnair flights, so decided to build a points calculator. Only works for AY marketed and operated flights and AY+ program. There's no check for valid routes, so even though the flight DFW - JFK will show the points, those are obviously incorrect as AY doesn't fly the route. Might add some validation/warning in the future.

The main issue with the other OW airlines/programs is lack of data. If anyone knows how to calculate those points, let me know and I'll try to incorporate that logic. Also added a page where you can calculate how many flights are needed to reach a specific tier. If there's any issues, let me know. Here's the URL for the calculator: https://finnair-pc.vercel.app/
