Family of 3 (2 adults + 1 infant) - just booked flights to the Maldives with the intention to upgrade using Qcredits on the outbound and Avios on the inbound. To my surprise I could only upgrade the ticket of the adult without the in-lap infant online, so I opened a chat where they told me tickets with in-lap infants can't be upgraded with Avios or Qcredits. Does this mean my Qcredits are basically worthless now as they will expire in a year and the only travels I have planned for the next year are with the baby?

Any workaround other than booking flights with another airline and use my Miles to upgrade those flights?

Thanks!
