Passengers love Boeing 747s and Airbus A380s, AKA the world’s biggest commercial jets, but they’re slowly being phased out.

Emirates has the most Airbus A380 jets, but you can also enjoy the double-decker experience on British Airways, Qantas, Singapore Airlines and more.

Korean Air took delivery of 10 examples ... But it's not just the A380. Airlines around the world are holding onto other aging aircraft for longer than they would rather be rid of.

On the upper deck of the A380 is a lounge area with banquette-style seating, which business class passengers can use. The carrier is set to merge with Korean Air over the next couple of years.
