What's believe to be the last A320ceo jet that Airbus will build will be delivered soon to Delta. Built in Mobile, Ala., this A321ceo will mark the end of over three decades of history for a jetliner that has been a staple of the short-haul market. It had a production run of more than 8,100 aircraft. In November 2020 the last A320ceo built in Toulouse left the building as a corporate jet for the Royal Thai Air Force. Since then, only neos (new engine option) have been built in Toulouse. But the ceos (current engine option) have remained in production in Mobile. By December 2020, a backlog of 53 aircraft stood, but for various reasons not all of those orders are considered viable. Of those 53 orders, 22 were for Delta Air Lines. Now, just one aircraft remains to be delivered to Delta. MSN 10315 is widely considered to be the last A320ceo family jet to be built, and it’s an A321-211SL set to be delivered in the coming weeks. The final A321ceo has had two test flights, one Dec. 6 for a two-hour and 15-minute journey, and the second Dec. 10 for just over an hour and a half. (Source: SimplyFlying, 12/15/21)
