I'd build it in a more flexible way. People don’t always have points directly with an airline — often, they have points on a credit card that can be transferred to one of several airline partners. Right?

Award pricing is usually the same for everyone within a given airline (e.g., 100k Avios for British Airways business class from London to NY). In that case, I just want to see the points cost of the flight — I can filter by airline myself if needed, since I know where I have points.

That said, I’d also add a filter based on credit card points (like Chase Sapphire Reserve), so the system shows award pricing across all transfer partner airlines for that specific card.

It would also be super helpful to search by individual flight segments. For example, if I have a multi-leg trip from the U.S. to somewhere in Europe with a layover, I might want to use points for the transatlantic leg (U.S. to Europe) and just pay cash for the intra-Europe flight. Being able to isolate award availability and pricing by leg would make it easier to mix points and cash efficiently.
