Introduction

May 7, 2020, © Leeham News: With the Covid-19 pandemic depressing passenger traffic for years to come, we started an analysis last week on the options the airlines have who wait for their Boeing 777-9. Hold on to their 777-300ER or upgrade to the newer and more efficient 777-9?

We deepen the analysis this week by comparing the economics of a 10 years old 777-300ER versus a new 777-9.

Summary:

• The 777X is best seen as a cross between a Boeing 787 and a 777-300ER. It inherits the passenger comfort features the 787 brought to the market like lower cabin altitude, higher cabin humidity, larger windows, and a smoother ride.
• If a 777-9, with it's higher capital costs, can compete on operating cost with a used 777-300ER depends on the fuel price.
