Introduction  

May 14, 2020, © Leeham News: Last week, we compared the economics of the Boeing 777-300ER and 777-9 on the world’s busiest intercontinental route. The older aircraft proved a viable alternative, thanks to low fuel prices and low capital costs. We will now turn our attention to the step-down case mentioned in the article.

We will look at the market developments in the twin-aisle market and compare the economics of the 777-300ER with the 787-10 on the JFK to London Heathrow route to find out how attractive such an option is.

Summary

• 777X hot when launched;
• A materially different market for customers seven years on;
• Leads airlines to consider large twin order conversions.
