Wait time = hall queue + security (IoT sensors) + immigration (corporation estimate of 6, 8 or 10 min).
The four grades are the corporation’s own: under 20 min smooth, under 40 moderate, under 60 busy, 60 or more very busy. Measured by the corporation, not forecast, and collected every 30 minutes. Grades go by pass time, so a green row can still hold a long line.
At this congestion level, arrive at the airport 2.5 hours before departure. (based on the busiest hall · includes security & immigration buffer)

Tips for the security checkpoint
Once you clear security, every departure hall leads to the same airside (duty-free) area — they are all connected inside. So if the hall nearest your airline counter is crowded, use whichever hall has the shortest pass time, and if two are close, the one with fewer people waiting; that is the simplest way to save time.
[Carry-on liquids rule]
Liquids must be in containers of 100 ml or less, all fitting in a single transparent 1 L resealable bag. Containers larger than 100 ml are confiscated at security even if nearly empty, so pack them in checked baggage.
[Power banks & e-cigarettes]
Power banks, e-cigarettes and lighters cannot go in checked baggage due to fire risk. You must carry them in the cabin with you.
