All Nippon Airways*, Asiana Airlines, British Airways*, Emirates*, Etihad*, Korean Airlines, Lufthansa*, Qantas, Qatar Airways*, and Singapore Airlines* are still flying A380's. Unsurprisingly most of these [*] are also customers of future 777X deliveries. With the demise of the A380, the pending introduction of the 777X, and record-breaking orders for B787's and A350's it seems extremely unlikely that we will see another three or four engine widebody passenger aircraft enter production. That said, between recently built freighter models, future presidential transports, and a large established aftermarket the B747 is certain to outlast the A380 and continue flying for decades to come.I happened to be watching a YT video last night that showed Emirates still flying several A380's. Apparently they had mothballed them with expectations of having new 777X's to replace them, but the Boeing 777X project is way behind schedule so they had to put the 380's back in service.
