Burns and Ott, who are behind the blog godsavethepoints.com, funded the trip through the travel app JetSmarter, paying only with promo points.

Burns and Ott intend to take an overseas trip this summer and plan to use only miles. The couple suggested other sites and apps to help people save time and money when they travel.
