Wondering how much luggage you can take on a plane without paying extra? Your baggage allowance depends on the airline, route, cabin class and ticket type. Some tickets include a cabin suitcase and checked baggage, while cheaper fares may include only a small personal item.

This guide explains the difference between carry-on and checked baggage, how to check airline weight limits, and how to avoid unexpected baggage fees before reaching the airport.

1. What Is an Airline Baggage Allowance?

An airline baggage allowance is the amount and type of luggage a passenger may bring on a flight under the conditions of their ticket.

• Personal item: A small backpack, handbag or laptop bag that usually fits under the seat.
• Carry-on baggage: A cabin suitcase or larger bag stored in an overhead compartment, when included in your fare.
• Checked baggage: A suitcase handed to the airline at check-in and transported in the aircraft's cargo hold.
• Excess baggage: Luggage that exceeds the permitted weight, dimensions or number of pieces and may incur additional charges.

Do not assume that every ticket includes all three types of baggage. Always check the allowance attached to your booking.

2. Carry-On Baggage: Size and Weight Limits

Carry-on baggage rules differ between airlines. A suitcase accepted by one carrier may be too large, too heavy or not included in another airline's cheapest fare.

As a general reference, some airlines use cabin-bag dimensions around 55–56 cm high, but there is no single size or weight limit that applies to every airline worldwide. Wheels and handles may count toward the maximum dimensions.

Examples of Official Airline Rules

Airline	Example of published rules
Lufthansa	Many eligible fares include a cabin bag up to 55 × 40 × 23 cm and 8 kg. Economy Basic on some short- and medium-haul flights has a more limited allowance.
American Airlines	A standard carry-on can measure up to 22 × 14 × 9 inches. A personal item must fit under the seat and generally cannot exceed 18 × 14 × 8 inches.
Air Canada	Its standard carry-on dimensions are 55 × 40 × 23 cm. Some Economy Basic itineraries have different cabin-baggage entitlements.
Emirates	Its published Economy cabin-bag allowance generally has a 7 kg limit and maximum dimensions of 55 × 38 × 22 cm, subject to applicable conditions.

Important: These are examples, not a universal allowance or a guarantee for every booking. Fare rules, routes, aircraft and operating airlines can affect what you may bring. Check the official policy before travelling.

3. Checked Baggage: How Many Kilograms Are Allowed?

There is no universal checked-baggage allowance. Depending on the airline and ticket, your booking may include one or more suitcases, a combined weight allowance, or no checked baggage at all.

For example, one ticket might include a 23 kg suitcase, while another fare on a different airline or route might require you to purchase checked baggage separately. These examples should never be treated as a promise about your own booking.

Before travelling, confirm:

• The number of checked bags included in your fare.
• The maximum weight allowed for each bag.
• The maximum external dimensions, including wheels and handles.
• The price of adding baggage before departure.
• Whether your journey involves more than one airline.

For health and handling reasons, individual checked bags should generally be kept at or below 23 kg where possible. Many regions and airlines impose a 32 kg maximum for a single bag, but the applicable rules must be checked with the carrier.

4. What Can You Take on a Plane for Free?

Many travellers assume that a handbag, backpack and cabin suitcase are always included in the ticket price. That is not necessarily true.

Depending on the airline and fare, a ticket may include:

• One small personal item.
• A personal item plus a cabin suitcase.
• Checked baggage, either included or purchased separately.

Some airlines offer additional allowances for infants, mobility aids or certain medical equipment. The conditions vary, so contact your airline if you need to travel with special items.

Money-saving tip: Compare the final ticket price after adding the baggage you need. A cheaper ticket can become more expensive if it excludes your cabin suitcase or checked luggage.

5. How to Avoid Extra Baggage Fees

1. Check your ticket first. Look at your booking confirmation or the airline's Manage Booking section.
2. Measure your suitcase. Include wheels, handles and external pockets.
3. Weigh your luggage at home. Leave a little room below the permitted limit to allow for measurement differences.
4. Buy extra baggage in advance when appropriate. Compare the airline's online price with airport charges.
5. Check every flight in your itinerary. Different airlines may apply different baggage rules.
6. Keep valuables and essential documents with you. Follow airline rules for medicines, electronics and other restricted items.
7. Review your baggage allowance again before departure. Do not rely on an old screenshot or another passenger's experience.

6. What Happens If Your Bag Is Overweight?

If your suitcase exceeds the permitted weight or size, the airline may charge an excess-baggage fee, require you to repack, or refuse the bag under its conditions of carriage. Cabin baggage that does not meet the rules may also need to be checked, sometimes for an additional charge.

Charges vary by airline, route, airport and ticket. Check the exact amount with the carrier rather than relying on a general online estimate.

7. Special Rules for International Flights

International journeys can involve different baggage conditions when you change airlines or travel on separate tickets. The airline operating each flight, the route and the terms of your booking may affect your allowance.

Before a connecting journey, ask whether your checked baggage will be transferred automatically to the final destination or whether you must collect and recheck it. This can depend on the itinerary, airport procedures, immigration requirements and ticket arrangement.

Also check restrictions for liquids, batteries, sharp objects, sports equipment and other special items. Baggage allowance and security rules are separate requirements: a bag that meets the weight limit may still contain an item that cannot be carried in the cabin.

8. Where to Find the Correct Baggage Allowance

The safest source is the airline operating your flight and the baggage conditions associated with your exact ticket.

• IATA passenger baggage guidance
• Lufthansa baggage information
• American Airlines baggage information
• Air Canada baggage information
• Emirates baggage information

Airline rules can change. Always confirm the current allowance for your flight before packing, especially if you have purchased a basic or promotional fare.
