Places I've already been
There should be 4 swipe directions. If your main customer is someone that travels often they've probably been to some of the places suggested. Up swipe would mean "yes, I've been there and I loved it" and down swipe would be "yes, I've been there and didn't care for it".
The learning from this data will help suggest even better options along the way. Sure traveling to Seychelles is on my bucket list but if the flights I normally book are no longer than 10 hours and under $1000 why keep suggesting places with low conversion.
Thanks for the suggestion Thomas! I think it's a great idea and we will look into adding this functionality to the app soon.
