Packing for a flight should be simple and stress free. Yet baggage rules remain one of the most confusing parts of air travel. Weight limits, liquid rules, prohibited items, and excess charges often create last minute panic at airports.
This complete guide is created to remove every possible doubt related to flight baggage. After reading this page, travelers will clearly understand baggage allowance, what is allowed and not allowed on flights, how airport security works, and how to avoid delays and extra charges.
What Is Flight Baggage Allowance and Why It Matters
Flight baggage allowance refers to the maximum weight, size, and type of items a passenger can carry on a flight. These rules are set based on:
- Passenger safety
- Aircraft weight balance
- Airport security regulations
- International aviation laws
Knowing baggage rules helps travelers avoid confiscation, excess baggage fees, missed flights, and unnecessary stress.
Types of Baggage in Flights
Carry-On Baggage (Hand Baggage or Cabin Baggage)
Carry-on baggage is the bag you take inside the aircraft cabin.
Key features
- Stored in overhead bins or under the seat
- Strict size and weight limits
- Fully screened at security checkpoints
Commonly allowed items
- Laptop, tablet, mobile phone
- Wallet, passport, travel documents
- Chargers and power banks within limits
- One small personal item such as a handbag or laptop bag
Carry-on baggage plays a major role in faster boarding and quicker airport movement.
Checked Baggage (Check-In or Hold Baggage)
Checked baggage is handed over at the airline counter and travels in the aircraft cargo hold.
Key features
- Higher weight allowance
- Suitable for large suitcases
- No access during the flight
Commonly packed items
- Clothes and footwear
- Toiletries over 100 ml
- Gifts and non-essential items
Most baggage mistakes happen in checked baggage due to restricted items.
Baggage Weight and Size Limits Explained
Carry-On Baggage Limits
- Usually 7 kg to 10 kg
- Must fit airline size templates
- Overweight cabin bags may be forced into check-in
Checked Baggage Limits
- Domestic flights usually allow around 15 kg
- International flights usually allow 20 to 30 kg
- Exceeding limits results in excess baggage charges
Always check baggage limits before travel as allowances vary by airline and ticket type.
Airport Security Screening Process Explained
Security screening ensures passenger and aircraft safety.
What happens during screening
- Carry-on baggage goes through X-ray scanners
- Electronics may need to be removed
- Liquids are checked separately
- Metal objects may trigger body scanners
How to clear security faster
- Keep liquids and electronics easily accessible
- Remove belts, coins, and metal items early
- Avoid overpacking cabin baggage
Prepared travelers move through security smoothly.
The 100 ml Liquid Rule in Flights
This rule applies strictly to hand baggage only and is one of the most misunderstood airport security regulations.
- All liquids such as shampoo, toothpaste, creams, gels, perfumes, and lotions must be carried in containers of 100 ml or less. Every liquid container must fit inside one clear, resealable plastic bag.
- Even if a bottle is partially empty, the container size still matters. For example, a 200 ml bottle that is half-empty is not allowed in hand baggage. Security checks the container size, not the remaining quantity inside it.
Liquids that do not meet these requirements must be packed in checked baggage to avoid confiscation at security screening.
Liquids include
- Shampoo, conditioner, oil
- Perfume and deodorant sprays
- Creams, gels, toothpaste
Liquids above the limit must be packed in checked baggage.
