Terminal A will launch on November 1. However, the move will be done in phases and the current terminals will also be in use until November 14. From November 15, all flights will operate solely from the new terminal.
For those two weeks, passengers and those picking up or dropping off visitors are being urged to double-check information online at www.abudhabiairport.ae.
The new terminal is on track to open on schedule and all major services and facilities are ready for passengers, said a representative for Abu Dhabi Airports, which operates the travel hub.
To mark the opening, Etihad Airways' ceremonial flight is due to take off on Tuesday.
From November 1, Wizz Air Abu Dhabi and 15 other international airlines are scheduled to fly from the new terminal. From November 9, Etihad Airways will operate 16 flights from the terminal. And from November 14, a total of 28 airlines will operate from the terminal.
The terminal has been added to Google Maps and Waze, as well as other popular navigation apps. Motorway signs have also been added to the E10 and E11 as well as other locations in and around the facility.
Inter-terminal shuttle buses will carry passengers between buildings.
"We look forward to welcoming passengers to the state-of-the-art Terminal A," said Frank McCrorie, chief operations officer at Abu Dhabi Airports. "The new terminal will bring a major increase in capacity and access to world-class facilities for both passengers and airlines."
The building, which is triple the size of the old terminal at 74 hectares, is set to double the current airport's capacity and manage up to 45 million passengers per year.
More than 115 flights will operate from there, significantly increasing the frequency and reach of flights to and from Abu Dhabi.
