Airline baggage allowances decoded: what you can actually take

Airline baggage policies vary enormously, and misunderstanding them costs money and creates airport stress. Most airlines allow one checked bag and one carry-on bag, but beyond that, the details matter: weight limits, piece limits, size restrictions, and fees for excess baggage all differ. Before you pack, know your specific airline's exact policy—not a guess, but the actual rules for your booking.

Checked baggage typically has a weight limit (commonly 20kg for economy, sometimes 30kg) and size restrictions. Exceed the weight limit, and you'll pay a fee—sometimes a steep one. Carry-on baggage usually has tighter restrictions: one personal item plus one carry-on bag, with specific size dimensions. Airlines enforce these strictly, especially on full flights. If your carry-on is oversized, expect to check it at the gate, potentially incurring fees.

Special items—sports equipment, musical instruments, mobility aids—often have their own rules. Some airlines charge extra for these; others allow them as exceptions. Know before you pack. Also, liquids in carry-on must be under 100ml per container and fit in a single clear bag. This trips countless travellers. Pack any regulated items in your checked bag to avoid security delays.

The smartest move is to check your airline's baggage policy directly on their website using your booking reference. Screenshot or print it. Knowing exactly what you're allowed saves money, prevents last-minute panic, and keeps you moving smoothly through the airport. It's a small investment of time that pays for itself instantly.
