Wherever airport you go worldwide, there are always security checks. For frequent travellers, they already know the do’s and dont’s when checking in and passing thru the final security check. If there are long lines, you might probably noticed the retractable belt stanchion where you form the line. These belts only help to facilitate convenience and guidance.
I am not quite new anymore with security check controls because I am traveling from time to time. Always remember, no liquids allowed in your hand carry luggage or bags with over 100 ml quantity. You must also not exceed the 1 liter limit for total amount of liquids.
It is better to consult your airlines or any airport you will be starting your travel. Have a safe trip to all travellers out there!
