What this means for a claim: ATFM delays come from weather (6% here), air traffic control capacity and staffing (94%) or airport limits – causes airlines often cite as extraordinary circumstances. They are only part of the story: most long delays come from the airline’s own operation (technical faults, crew, late inbound aircraft), which this data does not show. Source: EUROCONTROL.
