January 04, 2016, © Leeham Co.: We have discussed if the Boeing 767-300ER could function as a stopgap until an NMA would be available. We then compared it with Boeing's 787-8 and Airbus' A330-800 as alternative stopgaps. We didn't include any single-aisle alternatives at the time, like Airbus' A321LR or Boeing’s 737 MAX 10.
These aircraft have limitations in passenger capacity and range compared with the 767. The least compromised aircraft in an NMA role is the A321LR, which comes within 1,500nm of the range of the 767-300ER. We, therefore, use it as our single-aisle alternative when we look at further stopgaps until an NMA arrives in 7-10 years.
