Boeing has delivered the first 777-300ER to Guggenheim, which will lease the aircraft to Korean Air.

The 777-300ER can seat up to 365 passengers in a three-class configuration and fly 7,930nm at Mach 0.84.

The twin-engine, twin-aisle aircraft produces 22% less carbon dioxide per seat and costs 20% less to operate per seat than other aircraft in its class.

The 777 will be the 25th 777 for Korean Air and Guggenheim is expected to receive five additional 777s under the contract.

Guggenheim Aviation is a commercial aircraft leasing firm with a presence in Seattle, London and Singapore, while Korean Air is based in Seoul.
