Hey HN, We're Steve and Tom (YC S18), the co-founders of Duffel (https://duffel.com/), an API-based travel platform. Think of Stripe, but for searching and booking flights. We built Duffel after running head first into the problem of accessing airline inventory for a side-project that we had. All the providers out there (ever heard of a GDS? Amadeus? Sabre?) felt antiquated, expensive and quite frankly didn't even want to work with us.

Hi there, TLDR; I built an inbox simulator so you can try BonBook in 15s, without sharing your email. Earlier this year I was flying 2-3 times per month and found booking and changing flights a hassle. So I decided to fix it. BonBook lets you find, book and change flights with one email. It can also auto-find flights for events you’re attending. Over the last few days, I built a simulator that lets you interact with BonBook without sharing your email. It responds with real flights and each response includes a link to compare w/ Google.

Generous free tier (happy to give more credits, lmk) + super low pricing. Lmk any thoughts or improvement ideas :)
