The amount depends only on distance (771 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.
