I wonder if since it's filming in the winter if they'll go somewhere snowy or stick to somewhere warm for the finale. They've hit most of the warm weather big metros and they almost always have them in airline hub cities. Eyeballing it now that 31 was in Detroit, Charlotte, SLC, Boston, and MSP are the only hub cities they haven't visited yet. SLC would be a cool place to visit if they choose cold and it's a Delta hub. If they're coming from Asia, they'd have to make a connection though bc for now all the long haul internationals they do out of there are to Europe.
