Glad to hear that! I have one friend who has built a reasonably successful luxury travel business, but I have at least 5 others who are functionally free APIs for their friends. I would love to see this as an emergent specialty space - imagine if a frequent traveller like the ones I'm referring to could plan their trips, but also easily create them to share and sell to others.
Exactly what excited us about building Duffel in the first place. (After we struggled to get access to a decent travel booking API ourselves).
We want to give everyone the opportunity to sell travel products, anywhere.
