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. To top it up, once we started digging the only things we could hear were "PNR", "IATA", "ARC", "RBD" and other wonderful acronyms. It’s…

Spelt▲94I was frustrated with existing APIs for searching flight prices, so I built this. It's a simple API to search for flights and get their prices. It can also return booking links. Generous free tier (happy to give more credits, lmk) + super low pricing. Lmk any thoughts or improvement ideas :)

My friend and I built BookMyFlight to finally modernize flight search + booking. Why we built this: - Personalization. I fly the same route every month, and there’s no platform that knows my preferences so that I can open it, find and book my flight, and close it within a minute. - Booking is slow. I hate seeing a long clunky airline form each time I need to book. I want booking a flight to feel more like booking an Uber. How it works: 1. Optionally make an account and save your traveler preferences. Personally, I've specified my routine route as SFO to CLE and that I only want red-eye…
