📒 Baggage Rules Made Simple: A Quick Guide for Savvy Travellers

Travelling from Country A to Country B? Which country’s guidelines should you look at? Don’t let baggage confusion slow you down. Here’s the breakdown:

1. Security Rules: Follow the Departure Country (Country A)

• Liquids, electronics, and other carry-on restrictions are dictated by Country A’s airport security. Even if Country B is more relaxed, you’ll need to comply at departure.

2. Baggage Allowances: Check Your Airline’s Policy

• Weight limits, sizes, and fees? That’s all up to your airline—not the countries. Avoid surprises by reviewing their rules before you pack.

3. Customs Rules: Respect the Arrival Country (Country B)

• Certain foods, medications, or goods might be fine in Country A but banned in Country B. When in doubt, leave it out—or check customs guidelines ahead of time.

Always check:

✅ Airline baggage policy

✅ Departure Country’s security rules

✅ Arrival Country’s customs restrictions

This article outlines baggage restrictions based on applicable aviation regulations, including the Civil Aviation Authority of Singapore (CAAS) requirements, Changi Airport Group(CAG) requirements, Immigration & Checkpoints Authority (ICA) requirements, International Air Transport Association (IATA) Dangerous Goods Regulations, and International Civil Aviation Organization (ICAO) Technical Instructions.
