"Furthermore, even from Boeing's wide-body offerings, there are alternative offerings that are likely to align more closely to the demands of the post-COVID-19 market. The 777X, despite the first deliveries having been delayed to 2022, is being billed as an advancement on the 787, and one of the most efficient products on the market. This aligns with rising demand for carbon-responsibility in the commercial aerospace industry. Regulations such as the International Civil Aviation Organization's CO2 emissions standards encourage airlines to integrate newer, more efficient models into their fleet. This renders the 777X a key product going forward."
