Welcome to FT!

Your route is ineligible as you will have too many North America segments (maximum of six) only one of which can be a nonstop transcontinental route, (e.g. SEA-JFK-PDX.) You also need to count every takeoff and landing as a segment against a maximum of 16; for example, there are no Paris-Portland nonstops, so you'd have to change planes someplace - maybe London, Dallas..? And count the additional segment.

Keep it up; you'll get there!
