Current projects at least before the start of the pandemic include, Sat 3 gates being designed with bus-stop like bench style seating after successful trial on Gate 43. Also installing new FEGP and stand guidance.
Fully automating the new shoreline check in desks to the baggage system.
New and improved security system added to Terminal forecourt area which eventually will be rolled out across all security lanes.
The Track Transit has had some refreshing works to the interior and better way finding installed.
Futurewise, the arrival terminal concept is under review/redesign with probably a more phased approach to opening.
Extension to the APV (Gates 90-93) for more bussing gates.
There was a potential redesign to the Sat 2 link, I think possibly making some use of the void space above the domestic lounge (Gates 80-88), maybe even removing the intl/domestic split at some point.
New MARS stands 81, 82 and 90-93 were completed end of last year. Possible in the future that dual taxilanes will be added to the Delta apron.
Of course all this is up in the air at the moment giving the current situation.
