Baggage fees are one of the most common sources of unexpected travel costs. Understanding airline baggage policies before you fly can save you money and prevent stressful surprises at the airport check-in desk.

Carry-On Baggage Rules

Most airlines allow one carry-on bag and one personal item (such as a laptop bag or small backpack) free of charge in economy class. The standard carry-on size limit is approximately 22 x 14 x 9 inches, though this varies by airline. Always check your specific carrier's rules before packing.

Checked Baggage Fees

Checked baggage fees vary widely by airline, route, and fare class. Budget carriers often charge for every bag, while full-service airlines may include one checked bag in certain fare types. Pre-purchasing baggage online is almost always cheaper than paying at the airport โ€” sometimes by 30โ€“50%.

Weight Limits

The standard weight limit for checked bags is 50 lbs (23 kg) in economy class. Bags over this limit incur overweight fees, which can be steep โ€” typically $100โ€“$200 extra. Weigh your bag at home before you travel to avoid surprises.

Oversized Baggage

Bags with total dimensions exceeding 62 inches (157 cm) are considered oversized and attract additional fees. Sports equipment like golf clubs, skis, and bicycles usually have specific policies and fees โ€” check with your airline directly.

Prohibited Items

Certain items are prohibited in both carry-on and checked baggage. These include explosives, flammable liquids, and certain lithium batteries. Items like knives and scissors are banned from carry-on but may be packed in checked bags. Always check the TSA or your local aviation authority's prohibited items list before packing.

Tips to Avoid Baggage Fees

Pack light and use only a carry-on if possible. If you must check a bag, pre-purchase it online when booking your flight. Consider airlines that include checked baggage in their fares. Use packing cubes to maximise space and keep weight down. Wear your heaviest items on the plane.
