These are observed aircraft, not an official airline fleet registry. Wet leases, codeshares, substitutions, ferry flights and reused flight identifiers can cause aircraft from another operator to appear here.

What this page means

The old Fleet List idea — rebuilt from observations.

The historical ACARSd Fleet List was based on aircraft actually heard using an airline's flight identifiers. This reconstruction follows the same principle and now combines the restored ACARS archive with new Mode-S / ADS-B observations where available.
