Question: how many avios points do i need to upgrade from economy to business?
Answer: The cost of the upgrade is the difference between a standard Avios redemption in the two classes. A one-way peak Premium Economy / World Traveller Plus ticket to Dubai is 40,000 Avios for example, whilst Business Class / Club World is 60,000 Avios. It would therefore cost 20,000 Avios each-way to upgrade the ticket.
