The Airbus A380 is the iconic double-decker aircraft that still demands a grand presence at every airport it serves. While the number of A380 operators has dwindled, several airlines still use these superjumbos on key international routes. Singapore Airlines was the inaugural operator of the type, deploying the A380 between Singapore Changi Airport (SIN) and Sydney Kingsford Smith Airport (SYD); since then it has expanded its reach.
