Cool idea!

Is this product of interest to Europeans?

It is unclear from the signup page.

It seems the search would be useful for Europeans who manage to gather airline points, but that would be much less common in Europe than in the US, due to the lack of credit card awards programs.

Thank you! On the European side, we do support Flying Blue (Air France & KLM), SAS, and Virgin Atlantic loyalty programs.
