Hello,

What data source do you use for edits? I'm asking because it seems it's outdated and according to the IATA website, the QZD IATA code is no longer assigned to Szeged Airport: https://www.iata.org/en/publications/directories/code-search/?airport.search=QZD

The IATA code was removed in https://www.openstreetmap.org/changeset/145289830
