Every airline may have different maximum size and weight limits for cabin size and check-in luggage. While it is typical for airlines to check the weight of your check-in bags, not all airlines will measure the dimensions of your check-in luggage. Equally, not all carriers will check the size and weight of your hand luggage. In case of low-cost carriers it is however not unusual that the size of your cabin bag will be checked. In the case your hand luggage exceeds the size and weight limits many low-cost carriers allow you to carry the item with you against a surcharge. In other cases you might be asked to check-in your suitcase (sometimes against a fee). If your check-in luggage exceeds the weight or size limits the airline has the right to charge for overweight or oversize luggage. The exact cost may vary depending on the airline.
