The amount depends only on distance (2,225 km, measured as the great circle between the airports) – not on the ticket price – and is paid per passenger, children included. Whatever the cause, from 2 hours’ delay the airline must provide care (meals, drinks, a hotel overnight), and after a cancellation you choose between a refund or re-routing.

What this means for a claim: ATFM delays come from weather (25% here), air traffic control capacity and staffing (46%) 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.
