Trial operations at Abu Dhabi International Airport's Midfield terminal building have begun ahead of opening in November.
More than 6,000 volunteers took part in the airport's largest trial and test exercise to date.
All systems including check-in and baggage handling, security screening, boarding gates, immigration were stringently tested.
Volunteers assessed the speed and accuracy of check-in, including document and customs inspections.
They also tested boarding routines and assessed flight information procedures.
“Our commitment to excellence has driven our journey to prepare for Terminal A's opening, as we are focused on conducting extensive, large-scale assessments to ensure the speed, efficiency and delivery of operations,” said Elena Sorlini, managing director and interim chief executive at Abu Dhabi Airports.
“I would like to thank the volunteers who have participated in these trials for their unwavering support as we gear up to welcome passengers to Terminal A in November.”
The building is expected to accommodate up to 45 million passengers per year, process 11,000 travellers an hour and operate 79 aircraft at any given time.
At 742,000 square metres, it is one of the largest airport terminals in the world and will increase Abu Dhabi International Airport's passenger and cargo capacity significantly.
Etihad Airways, Wizz Air Abu Dhabi and Air Arabia Abu Dhabi will be moving to Terminal A on opening.
Construction began in 2012 and it was originally scheduled for completion in 2017.
