There are almost no absolutely free APIs in the travel industry. One way or another, you have to pay for product use. That said, you may enroll in affiliate programs to share commission fees with a provider or just try sandbox versions for your MVP. Here are some popular APIs that you can get kinda free or with shared fees.

Travel Innovation Sandbox by Amadeus
Sandbox APIs include: flights, hotels, cars, trains, and points of interest.
How? Just register, get your API key, and you’re good to go.

API Explorer by Sabre

Hey. I was looking for a travel API too and came across this post.
After a way long search with a tight budget, I also agree that there is no such thing as a “free travel API”. The ones I tried out were a complete waste of time. 
I found this provider called Aviation Edge on Google though and gave it a shot. The number one reason we wanted to give them a shot was that they have a reduced price offer for the first month so we were able to test the data for 5 bucks only. I’ll use AltexSoft’s way in the response to let you know our experience 🙂
Link for you to see their scope of data:
Aviation Edge API
Provides live flight info and airport schedules. They also have passive data APIs for airlines, airplanes, routes, cities, airport etc. at no add. charge. Having them as extra is a plus even if you don’t need them now.
How? Easily follow the steps to subscription on this link and the API key is sent to you automatically. They have guidelines on the usage on their website too.
Limitations. They have several packages for different levels of needs. The smallest one has 30.000 API calls monthly and the largest has 500.000. You can also apply for an Unlimited package if you need more than 500k.
Use cases. Any field that doesn’t require data on far-future flights as they don’t provide that but only live ones. 
My notes. I compared the data to other more expensive options. Haven’t spotted any discrepancies. They fully cover the data on airlines that are a must for us, at least. Uptimes are good and so has been the integration.
I say they are definitely worth testing. The only downside is that they don’t have data on historical and future flights. We’ve been saving the data on our end to use it as historical data in the future but if you are looking for earlier-historical or far-future flights it might be a bit tricky. It’s fine for our project though.
Hope our little experience helps you!
