What are the pros and cons of integrating Skyscanner API for flight search?

Question

Answer

Skyscanner is a large metasearch engine that provides a set of info APIs totally free. This means you can source their data, but you won’t be able to set booking on your website. You have to redirect users to either Skyscanner or straight to a supplier. But, you can earn a commission once you generate more than about $1300 worth of revenue per month. To do that, you must first get API access as Skyscanner vets candidates and not all of them are rewarded with access. Once you reach the $1300 threshold, you can sign a contract with Skyscanner and directly negotiate your commission.
Advantages:

Skyscanner is a well-recognized metasearch business that has been on the market since 2001 and currently accesses about 1200 providers worldwide.
They keep their tech and documentation up to date. It’s transparent: You can always ask questions and solve problems.
They use RESTful API with both JSON and XML available.
You get access to both cached and live data. For instance, you can use cached data (that updates up to every 14 days for unpopular routes and more often for popular ones) to make flex search comparison of flight fares and retrieve live quotes for specific dates that a user requests.
You can enroll in a partnership for free. And once you start generating more than £1000 or ~$1300, you can start earning.

Disadvantages:

The main problem is that not just any business gets accepted by Skyscanner. Even though theoretically everyone can get access, they’ll vet your company to make sure that you are capable of generating revenue and attracting users.
No surprise, there are limits. If you’re looking for live prices, you can make up to 100 calls per minute.
Skyscanner forbids caching on your side. In other words, you can’t store old prices to build, say, a flex-fare search based on previous user requests. You still have to use their cache, which is limited to 500 fares per minute.
You have to make sure that all your customers know that your app is powered by Skyscanner by adding a message to that effect. Theoretically, you can negotiate something else, but you must refer to them by default.
