The new terminal is massive... what seemed to be a single level airport from outside simply changed as we approached it. They've dug down 3 levels, all spaces have a really height ceiling. Check-in counters are located in the middle of the each hall (2 halls in total) with belts going under into the lower level for luggage processing.
Whole trial seemed 99% real, real check-in, real passport control, all up to the point where we had to enter the aircraft which obviously wasn't there. Instead we were diverted from the same boarding bay into arrival hall where we had to pass another passport control and pick up our luggage.
