How do I find the registration or serial number for the aircraft I flew on specific trips in the past? - White and Black Road Sign on Green Grass Field

I understand that there are various paid subscription services that allow me to search back up to a year in the past for the IDs of any flight and the histories of any aircraft.

Is there a free (or one-time fee) service or API for identifying the aircraft I've flown on specific dates and flights in the (up to several years) past?



Best Answer

I've asked one of my customers who works in the field, and he pointed me to this:

https://opensky-network.org/

I've never used it myself (I didn't know of it's existence 'till like half an hour ago), so I can grant for it. Let us know if it worked!


And while we are here, a small explanation 'bout why it's quite difficult to find those data for free.

The basic problem are:

  1. Flights data are complex to retrieve, as there is not a single, central, shared information system where everybody connects to store and retrieve data, so entities interested in this kind of information must house-build a system that connect to a plethora of different companies/organizations/servers/API. This is obviously really expensive, so they need costly licenses to get their money back.
  2. After you retrieve the data as per point 1 you need to "translate" them to a common format which works well for you and then store the results. There are on average 100.000 commercial, passengers flights everyday, which means that when you are going to store each flight basic data (flight codes, airports involved, time of departure and landing, textual data, and so on) plus their real flight path data, you begin to have to store a lot of data, so you need lot of money for the storage infrastructure too, and that add to the costs for the data retrieval infrastructure too.

So, in conclusion, it takes a lot of money to build a service like that.

How do I look up flight history?

If you're at a gate and can't actually see the plane's registration code, you can cross-reference Flightradar24. If you look up a flight number there, it will typically show the registration code for the plane operating the flight, which you can then use to look up the history of the plane.

Can you track an old flight?

With each WebTrak map, you can track current and past flights. The default is current flights. You'll see them on a Google Map with which you can zoom in and out and hover over or click on planes to get more info\u2014like flight ID, aircraft type, origin and destination airports, and altitude.

Where can I find plane registration number?

It is typically displayed as follows:
  • On the side of the fuselage near the rear of the plane, or on the tail or fuselage-mounted engine.
  • It may also be located under the left wing.
  • A shortened version of the number may also appear on the nosewheel door of the front landing gear.


  • What is the difference between flight number and aircraft registration number?

    The flight designator of the operating carrier of a commercial flight is used as a call sign. This is distinct from the aircraft's registration number, which identifies a specific airplane.
