Allowance depends on the fare
The same airline may sell fares with no checked bag, one bag or two. Weight and size limits also differ by airline and cabin class, so read the allowance shown for your exact ticket.
Cabin baggage and personal items
Many airlines separate a cabin bag from a smaller personal item that fits under the seat. Size and weight limits for each are set by the carrier, and some budget fares allow only the personal item.
Connections with different airlines
On a single ticket the first airline usually dictates the allowance for the whole journey; on separate tickets each flight applies its own rules and you may need to collect and recheck your bags.
Restricted items
Liquids in hand baggage, power banks and lithium batteries, sports equipment and similar items are regulated by aviation security and the airline. Check the airline and airport security pages before packing.
Buy extras in advance
Adding baggage online before the flight is usually cheaper than paying at the airport, though prices depend on the airline.
