If you upgrade online or at check-in you will receive the excess baggage allowance applicable to the class of your upgrade. Please read the FAQ to see where exceptions to excess baggage allowances may apply due to airport regulations.
If you are travelling on multiple flights during one journey, an upgraded baggage allowance only applies to the part of the journey that has been upgraded. On the other flights during the journey, you will need to either upgrade again or pay the extra fee for the heavier baggage.
