I have looked everywhere for the past week to find the flight schedule origins. I know this information is coming from airlines and they will be discussed and sent to FAA. I wonder how some services like flightLabs are getting this data, which they turn into an API.

I just want to get a simple list of flights for a specific date between two airports and that seems to be a tough task to do using any API. I even thought of creating my own API, but now I don't know where to get my hands on this type of information.

Any help will be appreciated.

  • Are you interested in the past, the present, or the future? And what data exactly would you need? And what coverage (countries)?

  • See rapidapi.com/collection/flight-data-apis for a few possible sources, but there are many others. Note that most require a payment, but a few will have limited free tiers, so it depends on how much data you need, at what frequency, and your use case after that.

  • @jcaron just the current and future flights. Yes, I have looked into that, but they have some high price tags for a little amount of data.

This comes up regularly, and to the best of my knowledge, there is no free & reliable source of flight schedules.

You can purchase commercial subscriptions to various services that provide flight information, but expect to pay quite a bit for the privilege. OAG is the original source of the data.

  • I would think there are alternative original sources for schedule data, especially the GDS (Amadeus, Galileo, Sabre...).

    @jcaron GDSes source their information from OAG as well. Commented Jan 26 at 11:44
  • So all those services are paying OAG for the privilege and then charging their customers?

    @MehraD Airlines willingly share their data with OAG, and this gives them their biggest advantage, visibility into future flights that have been announced but are not operating yet, and thus cannot be scraped from public data. Commented Jan 30 at 6:08
