On 7 September 2015, Airbus announced that it had begun production of the first A330neo with the construction of its centre wingbox and engine pylon.
Final assembly of the first aircraft, an A330-900, started in September 2016 at the Toulouse Line with the station 40 centre fuselage and wings join.
In December 2016, the program schedule slipped by six weeks due to marginal engine development at Rolls-Royce, and launch customer TAP Air Portugal projected its first A330neo would be delivered in March 2018.

The first aircraft left the paint shop in December 2016, awaiting its engines.
Its first flight was delayed until September 2017 after the Rolls-Royce Trent 7000s were installed during the summer.

After this delay, TAP Air Portugal was expected to receive the first A330neo at the end of the first half of 2018, or even in the third quarter.

The engines were shipped to Airbus in June.
The aircraft complete with engines showed at Toulouse in September before its first flight.

Major structures of the first A330-800 were entering production in October 2017: high-lift devices are installed on the wing in Bremen, fuselage sections are built in Hamburg, the centre wing-box in Nantes, titanium engine pylons in Toulouse and sharklet wingtips in Korea.
Its final assembly started in November 2017, on track for its planned first flight in mid-2018.

Structural assembly was completed by February 2018, having its flight-test instruments installed and waiting for its engines before its 300h flight-test programme.

At this time, production aircraft progressed through the final assembly line with the first 'Airspace' cabin interior being fitted.

A330 production was cut to 50 deliveries in 2019, with more than half of them re-engined A330neos.

In April 2020, the production rate decreased from 3.5 to 2 per month due to the impact of the COVID-19 pandemic on aviation, and finished planes were stored while waiting for deferred deliveries.
