Do you have a link to this offer?
I am just finishing up a similar promotion from QR (Globetrotter, 100k miles).
Are we sure that multi-city (one-way) itineraries qualify? (It did for the QR-campaign).
Are we sure that your hometown qualifies? (It did not for the QR-campaign).
I love these kind of promotions, as you will both experience places you didn't plan on going, and earning miles doing so
