- Changes in security, landside access, metro connectivity, parking and curbside policy

- Target employee and recurring-traveller demand with subscriptions, loyalty partnerships, late-night trading and value-led meal propositions.
- Model concession exposure carefully: prioritise high-throughput locations and flexible lease structures ahead of Terminal 4 tender activity.
- Develop formats that can trade across terminals, Aerocity hotels and offices, using shared kitchens, inventory pools and common loyalty data.
