This new regulations limited the quantity and quality of liquids to pass through the airport control and as a result passenger can only carry little amounts of liquids in a very specific circumstances. Passengers are not allowed to carry a total amount of one liter or 33.8 ounces.

All the containers must be storage in a squared-shaped Ziploc plastic bag measuring 20 x 20 centimeters or 7.8 x 7.8 inches.

This new ordinances allow passengers to transport 100 milliliters or 3.8 ounces of liquid medicines, baby food and special food in their carry-on luggage.
