The correct comparison
A cabin bag is part of the fare calculation.
Two fares can display the same price but include different baggage. Before choosing, open the fare conditions and confirm the permitted cabin bag, personal item and checked baggage.
Do not assume a bag allowed on one airline will be accepted on another. Aircraft type, fare family and operating carrier can affect the rule.
At the airport
A bag that does not comply can be moved to the hold.
Airlines can weigh or size a cabin bag at check-in or the gate. Over-limit baggage may need to be checked, and late changes can cost more than adding baggage earlier.
Keep medication, identification, valuables and essential electronics in an item that remains with you, subject to security rules and the airline’s conditions.
Packing decision
Measure once before the trip.
| Check | What to confirm |
|---|---|
| Dimensions | The airline’s current length, width and height limits |
| Weight | Whether the allowance is per item or combined |
| Personal item | Whether a handbag or laptop bag is additional |
| Fare family | Whether the selected fare changes the allowance |
| Operating carrier | The airline actually flying the aircraft |
| Return sector | The same rule may not apply if the airline changes |
Policies change. Verify the exact airline and fare rules shown on your booking before departure.
