As air travel continues to evolve, understanding these changes is crucial for a smooth and hassle-free journey.
This article provides a comprehensive overview of the new rules, including container limits, screening procedures, exemptions, and essential packing tips for travelers. Whether you’re a frequent flyer or planning your first trip, being informed will help you navigate these regulations effectively.
Updated Security Measures
On April 22, 2025, the Royal Gazette announced immediate changes to the guidelines concerning LGAs. The Civil Aviation Authority of Thailand (CAAT) is enforcing these rules to ensure safety for passengers, crew members, and airport personnel.
Key Aspects of the New Regulations
All LGAs will undergo rigorous screening before they are allowed into restricted areas or aircraft cabins. The term "LGAs" encompasses a variety of items, including:
- Beverages and Soups: This includes any drinks, such as water, juices, and soups.
- Cosmetics and Toiletries: Items like toothpaste, lotions, and creams fall under this category.
- Pressurized Containers: This includes items like spray deodorants and shaving foams.
- Solid-Liquid Mixtures: Products such as mascara and lip balm are also classified as LGAs.
Container Limits
-
Individual Container Size: Each container holding liquids, gels, or aerosols must not exceed 100 milliliters. This rule applies even if the container is not full.
-
Total Volume Allowance: Passengers can carry several small containers, but the total volume of all LGAs must not exceed one liter per person.
-
Re-sealable Bag Requirement: Travelers are required to place these containers in a single, transparent, re-sealable plastic bag. This bag can hold a maximum of one liter and is limited to one bag per passenger. Security staff will screen this bag separately.
Additional Screening Procedures
At security checkpoints, personnel will conduct separate screenings for the transparent bag containing LGAs. However, if the airport uses advanced X-ray technology, it may allow for the inspection of these items within carry-on luggage.
Larger Quantities in Hold Luggage
If you have liquids, gels, or aerosols in containers larger than 100 milliliters or exceeding the one-liter total limit, these items must be checked in as hold luggage.
Prohibited Items
The new regulations strictly prohibit any individual container of liquids larger than 100 milliliters from being brought into the cabin. This measure aims to prevent the transport of large quantities of potentially harmful substances. Here’s a breakdown of restricted items:
-
Beverages and Liquids: All drinks, including water and juices, must comply with the 100ml limit. Larger bottles purchased before security must be checked in.
-
Gels and Lotions: This includes lotions, creams, moisturizers, and other similar products.
-
Cosmetics: Items like mascara, liquid foundation, and lip gloss are subject to the new size limits.
-
Aerosols and Sprays: Perfumes, deodorants, and hair sprays must be packed according to these regulations, even if they appear to be partially full.
-
Pressurized Containers: Items such as whipped cream cans must also adhere to the 100ml limit.
Exemptions to the Rules
Certain essential items are permitted in quantities exceeding the standard limits but must still undergo security screening. These exemptions include:
-
Medications: Passengers can carry essential medications with proper documentation, such as a doctor’s note or a prescription label that matches the traveler’s name.
-
Baby Food and Special Diet Items: Travelers with necessary baby milk or dietary food for medical reasons can bring what they need for the duration of the flight, subject to inspection.
-
Crew and Essential Personnel: Airline crew members and airport staff may carry reasonable amounts of LGAs needed during their duty hours, but they must still pass security checks.
-
Emergency and Airport Staff: Personnel authorized to access restricted areas or respond to emergencies can carry duty-related LGAs, provided they pass screening.
-
Duty-Free Purchases: Liquids bought at airport duty-free shops or on board aircraft are allowed if they are sealed in tamper-evident bags with proof of same-day purchase.
