IATA Guidelines

Airlines establish regulations for checked and carry-on baggage, including potential charges. Rules may vary based on factors like frequent flyer status, purchased product, and travel route. The information below outlines IATA's role in understanding these regulations.

Carry-on Baggage

1. Weight and Size:
   The allowance for carry-on baggage varies by airline, cabin class, and aircraft size. Generally, dimensions should not exceed 22 in (56 cm) length, 18 in (45 cm) width, and 10 in (25 cm) depth, including wheels and handles. Some airlines also impose weight limits, often starting at 5kg/11lbs. Check with your airline before travel to know your specific allowance.


2. Portable Electronic Devices & Lithium Batteries:
   Lithium batteries in devices, electronic cigarettes, or power banks must be in carry-on baggage, not checked. Spare batteries should be individually wrapped to prevent short circuits.


3. Sharp Objects:
   Knives, sharp objects, and certain sporting goods must be in checked baggage, not in cabin baggage or on your person.


4. Liquids, Aerosols, Gels & Powders:
   Restrictions on liquids, aerosols, and gels in carry-on baggage follow ICAO guidelines, typically limited to 100ml containers in a transparent 1-liter plastic bag. Additional screening may apply to powders exceeding 355ml/12 ounces at some airports.


5. Medical Supplies:
   If using medical syringes like insulin, carry documented proof of necessity and ensure professional packing.


6. Where to Put Your Carry-on Baggage:
   Store baggage under the seat or in overhead compartments. In emergencies, follow cabin crew instructions. Unclaimed bags may be removed.


7. Keeping Your Carry-on Baggage Secure:
   Do not leave baggage unattended in or around airport terminals. Using a padlock is a wise precaution against theft.

Checked Baggage

1. Weight, Size, and Number:
   Airlines have varying rules for free checked baggage, influenced by factors like airline, frequent flyer status, routing, and fare. Ensure awareness of your checked baggage allowance to avoid additional charges. Generally, each bag should weigh less than 23KG/50LBS, with a maximum weight of 32KG/70LBS in the EU and the US. The "piece concept" may apply, allowing two pieces per passenger with specific weight and size limits.


2. Identification:
   To prevent lost baggage, prominently display your name, phone number, and email address on the outside. Place a copy of your travel itinerary inside for easy identification in case the baggage label detaches.


3. Valuables:
   Avoid packing valuable items in checked baggage to minimize the risk of loss.


4. What Not To Pack In Checked Baggage:
   Portable electronic devices are recommended in carry-on baggage. If packed in checked baggage, ensure they are switched off. Electronic cigarettes, spare batteries, and power banks should not be in checked baggage. Certain items like gas canisters, lighters, fireworks, and bleaches are prohibited. Check with your airline for specific restrictions.

Handling Missing Checked Baggage

Globally, 99.5% of baggage travels as planned, with most mishandled bags returned within 48 hours. Despite this, arriving without your baggage is inconvenient. Baggage mishandlings, often due to transfer point issues, are actively addressed by IATA and its members. In the rare event of missing baggage, promptly file a report in the baggage reclaim area before leaving the airport.
