Introduction
Nov. 3, 2022, © Leeham News: Last week, we described the New Production Standard (NPS) of the Airbus A350. Now we look at the economic performance of the A350-900 versus the Boeing 787-10 on the world’s busiest long-haul route, London Heathrow to New York JFK.
We compare the economics with a nine abreast economy cabin and what difference the NPS and a 10 abrest change for the A350 produces.
