This looks very promising, but it's relatively unusable at the moment. When I type in an origin airport, deselect all destination regions except North America, and sort by CPM, the first few pages of results are Europe to the supposed origin airport (of course because the results lack the YQ). It seems like the tool is treating the inputted airport as either origin OR destination, where it should only be the origin, with the regions with the checkboxes as destinations.

Also, when filtering by carrier, there does not seem to be a way to select a single carrier without deselecting each and every one of the others. Obviously that's not practical. Maybe it's just a problem on my end, though, because your screenshots show checkboxes that would appear to control the whole column.

I'll keep playing around with it. It looks like it could be great, and thanks for taking the time to develop it ^
