From the drop-off belt to the reclaim carousel

Checked baggage is a logistics system with a small number of rules that are enforced consistently. Almost every problem at bag drop comes from weight, from prohibited items or from arriving after the cut-off.

This guide follows a bag through the whole journey so you know what happens after it disappears behind the curtain.

Allowances, weight and fees

Fare typeTypical checked allowance
Basic or hand-baggage-onlyNone, paid separately
Standard economy, short haulOne bag up to 20 to 23 kg
Standard economy, long haulOne or two bags up to 23 kg each
Premium and businessTwo bags, often up to 32 kg each

Paying online is nearly always cheaper than paying at the airport. Excess weight charges at the desk are deliberately expensive.

Bag drop and tagging

Checked baggage - practical detail
  • The printed tag carries your flight, destination and a unique number.
  • The stub you keep is the proof of carriage. Photograph it as a backup.
  • Remove old tags. Scanners and handlers read whatever is attached.
  • Self-service drop is usually faster, but weight limits are enforced by the machine.

What cannot go in the hold

  • Spare lithium batteries and power banks must travel in the cabin.
  • Aerosols beyond small toiletry quantities are restricted.
  • Flammable liquids, camping gas and most lighters are prohibited.
  • Valuables, medication and travel documents should never be checked.

Transfers between flights

On a single ticket the airline transfers bags for you. On separate tickets you reclaim and re-check. Some countries require you to reclaim bags on first entry regardless of the ticket, which is a common surprise for passengers connecting through them.

Reclaim and damage

  • Check the belt number on the arrivals screen; it changes without announcement.
  • Inspect the bag before leaving the hall. Damage claims are much harder afterwards.
  • Report damage or loss at the baggage service desk before you exit.

Frequently asked questions

How much can a checked bag weigh?
Commonly 23 kg on international economy fares, with 32 kg often the absolute handling limit per piece.
Can I put a power bank in checked baggage?
No. Spare lithium batteries and power banks must be carried in the cabin.
Do I collect my bag on a connection?
Not usually on a single ticket. On separate tickets, or where a country requires reclaim on first entry, yes.
When does bag drop close?
Typically 45 to 60 minutes before departure, and up to 90 minutes on some long-haul flights.
