Vietnam Airlines took delivery of its first Airbus A321neo Nov. 15, about two months later than anticipated. The aircraft was delivered in Hamburg, Germany, and is set to enter service Dec. 1. The carrier has 20 A321neos on order and deliveries were expected to begin in September, with a total of nine arriving by the end of the year. Problems with the Pratt & Whitney PW1100G engine, however, delayed delivery. The airline operates 58 A321ceos, three A330s and 12 A350-900s, and intends to bring the fleet to 110 aircraft by 2020.<br/>
