Korean Air is to introduce a new two-story A380 aircraft that features only Business Class seats on the second floor in May.

The 407-seat aircraft, built in partnership with Airbus, will be composed of 12 First Class, 94 Business Class and 301 Economy Class seats.

Korean Air says this deck will have 94 lie-flat sleeper seats, with 74in pitch. This will give business passengers a sense of “exclusivity”

Travellers on the upper deck will be able to feel “like they’re travelling in their own private jet”, says passenger business division chief Walter Cho.

Korean Air is to put the aircraft into service in May 2011, initially on short-haul routes to Japan and eastern Asia.

The air carrier plans to present a total of five A380 aircraft by the end of next year and additionally introduce another group of five by 2014.

Five other carriers operate the A380, with Air France‘s jets fitted with the highest-density layout of 538 seats.
