I called the Gold help line and they can only convert FTVs that were redeemed after 5th August to EMDs... if a FTV was redeemed prior to 5th August then they remain as a held booking on the original booking reference and the value is credited to each person on the booking... so must be used by each individual rather than pooled.

This is a real pain for me as it is unlikely that my daughter will use her voucher (which I paid for!!!) even though they are valid up to April 2022... she doesn't normally travel abroad. She might now!

The agent did say that this was the current state of play and that it may change in the future.
