Via Korean Air Cargo
Korean Air Cargo currently operates four 747-4B5F(ER) aircraft that fly medium cargo hauls around Southeast Asia. It holds up to 259,153 lbs of cargo and has a maximum range of a bit over 4500 nautical miles.
Korean Air has a vast cargo fleet, which is currently only represented by the 777-200F in IF. The 747-400F played a huge part of its cargo fleet before retirement and replacement by 747-8F variants started. I would love to see this marvelous cargo aircraft in IF if we get a 747-400F addition, and maybe even a 747-400BCF.
