Korean Air has agreed to purchase 50 new Boeing aircraft, as well as launching a new business class on long-haul aircraft.
The airline's order includes 20 Boeing 777-9 aircraft, 20 Boeing 787-10 aircraft and an option for 10 more 787-10s. The value of the deal was not disclosed.
The aircraft's "capability of long-haul flights to regions such as North America and Europe are expected to play an important role after Korean Air's merger with Asiana Airlines," according to Korean Air.
The US is the lone remaining market among 14 regulatory authorities needed to approve the merger with Asiana, but Korean Air CEO Walter Cho said last month that he expected US approval by October 2024.
Korean Air has also announced the delivery of its first Boeing 787-10 Dreamliner, which will operate between Seoul Incheon and Tokyo Narita airports from 25 July.
In addition, the aircraft will debut the carrier's new "Prestige Suites 2.0" business class product, which "prioritises passenger privacy”.
Each of the 36 business seats is "independent" and has aisle access with an open top, and each fully reclines into a bed.
The seat length has been extended to 78 inches, with a seat pitch of 46 inches and width of 21 inches, according to Korean Air. Each seat also offers dedicated compartments for personal items, 60W "ultrafast" USB-C charging and wireless charging.
The 289 economy class seats will be in a 3-3-3 configuration with a recline of up to 120 degrees, seat pitch of 32 inches and width of 17.2 inches.
