I redeemed points for a plan ahead award in 2019 for a 2020 US-EU flight that got cancelled due to covid, moved to mid 2021 and that flight was also cancelled. The flight can be booked up until end of March 2022, but of course there has been very little U space for booking. Agent said that they could deposit the business extra points to my account and I could try and redeem them for plan ahead certificates instead.

If I redeposit the points into Business Extra, will they just be expired or will can I still redeem them for something else?

Points originally expired end of 2019.
