Airline Baggage Rules Explained — Fees & Limits
How do airline baggage allowances work?
Your allowance depends on the operating airline, fare brand, route, and sometimes loyalty status. Carry-on size limits and personal item rules are enforced at the gate. Checked bags are priced per direction and may cost more at the airport than if prepaid online or by phone.
Detailed explanation
Codeshare flights usually follow the operating carrier’s baggage chart even if you booked through a partner name. International trips may include a free checked bag on full-fare economy while basic economy is carry-on only. Specialty items—skis, strollers, musical instruments—have dimension and weight tables you should verify before packing.
Important conditions and limits
- Overweight and oversize fees apply even when the first bag is free.
- Interline agreements may not transfer bags on separate tickets you booked yourself.
- Lithium battery rules differ for checked versus carry-on storage.
- Duty-free liquids may be restricted on connections through certain countries.

Do basic economy tickets include a carry-on bag?
It depends on the airline. Some basic fares allow only a personal item; others include a standard carry-on. Check your fare brand before packing.
Gate agents may force bag check with fees if your bag exceeds the published size. Measure at home first.
Which airline baggage rules apply on a codeshare flight?
Most trips follow the operating carrier’s chart even if you booked under a partner name. Confirm with flight numbers, not marketing brands alone.
On separate tickets you bought yourself, bags may not transfer. Plan time to reclaim and recheck if needed.
Is prepaid bag cheaper than paying at the airport?
Often yes. Many airlines charge more for checked bags at the counter or gate than when you add them earlier.
Phone or online prepaid options can lock the lower rate. Ask before airport day if your ticket still allows prepaid bags.

Airlines publish weight and dimension limits per bag. Exceeding either triggers extra fees even when the first bag is free.
Sports gear and instruments use special tables. Verify those items before you travel to avoid surprise charges.

Spare lithium batteries usually must stay in carry-on. Installed batteries in devices follow airline and security rules.
