💡 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 queue; 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.
