This efficient setup allows for consistently quick API response times even during times of high throughput.

  • Which type of historical flight data is available?

    Our system provides global flight data for the last 3 months as a sliding window, enabling the aviationstack API to deliver granular historical flight data, including information about routes, flight numbers, location, dates, times, airports, terminals, gates, aircrafts, and much more. You can learn more by reading our API documentation.

Plans, Pricing & Payment

  • What is the difference between free and paid subscriptions?

    The aviationstack Free Plan offers a way to implement the API in your application and try it out using real-time flight data.

    As soon as your use of the API requires a commercial license and a more advanced set of functionalities, such as historical data or airline routes, you can choose from one of the available paid subscriptions or contact us for a custom solution.

  • Which subscription plan fits my needs?

    The most decisive factor when it comes to your technical requirements is the number of API requests you need to make on a monthly basis. Other factors include license type, HTTPS encryption, access to airline routes, autocomplete features, historical data, and more.

    Signing up for the Free Plan is a great way of getting to know the API and implementing it without any commitments.

  • Which payment methods are supported?

    Payments can be made via credit card (Visa, MasterCard, Discover, Diner's Club, American Express). Enterprise and high-volume customers may request annual bank transfer payments to be enabled. You can change your payment method at any given time in the "Payment" section of your account dashboard.

  • Can I also pay yearly?

    Yes. If you choose annual billing, the total price of your subscription plan will be up to 20% lower than the total amount you would pay with a monthly payment frequency.

  • How can I change my payment frequency?

    In order to change your billing frequency from monthly to yearly or from yearly to monthly, you will be required to downgrade your account back to the Free Plan.

    Step 1: Navigate to the Subscription page, click "Downgrade" in the Free Plan section and confirm your downgrade. Downgrades are not effective immediately, your premium subscription will remain active until the end of the current billing period.

    Step 2: Once your billing period ends and your account downgrade has become effective, navigate back to the Subscription page and click "Upgrade" in your preferred subscription plan's section. You will now be aked to choose a new billing frequency.

    If you need any assistance changing your billing frequency, please do not hesitate to contact us.

API Access & Features

  • What is an API Request?

    Pricing is based on the number of monthly API requests allowed. Each time the aviationstack service is used to deliver aviation data, one API request is made. In the event that an error should occur, your request does not count towards the monthly volume.

  • What happens if I exceed my API Request volume?

    Users will be automatically notified via e-mail and on their Account Dashboard once at least 75%, 90%, and 100% of their monthly API Request allowance has been reached. After reaching 100% of the allowance, overages fees will apply so we make sure you won’t experience any disruptions and your website/application will keep running smoothly. You can learn more about overages billing here.

  • What is the API's uptime?

    Our API's system status is closely monitored around the clock. Every effort is made to ensure the highest possible level of availability and consistency, and we are proud to have an average uptime rate of nearly 100% (99.9%), calculated based on the past 12 months.
