April 4, 2024, © Leeham News: Korean Air confirmed an order for 33 Airbus A350 in the week, 27 of which are the larger A350-1000. The order is significant on two accounts:

First, 27 A350-1000 and only 6 A350-900, where analysts have for years asked why the -1000 isn’t selling.

Secondly, for a carrier that has a rather 50-50 fleet of Airbus and Boeing planes, its large widebody was the Boeing 777-300ER, whereof it has 27 out of 37 Boeing 777 in total. Korean Air now chooses the A350-1000 to replace the 777-300ER. Why not the 777-9?

Was this a question of availability (the 777-9 should have been delivered in 2020 but has had several delays; the present plan says 2025), or was there a technical-economic reason for Korean Air’s decision? We examine the characteristics of the two planes to find the answers.

Summary:
  • The Boeing 777-300ER was an exceptionally successful stretch of the original 777-200. The 777-9 is the sequel to the 777-300ER.
  • The market did not like the original A350-1000. Therefore, the present -1000 is a reconfigured aircraft compared to the original variant.
