It's now March so the "free refunds" option has expired, but I just received a couple vouchers from cancelled trips that I purchased prior to March.

Question is: Do I convert them to cash or leave them as vouchers? Do we know if I use them to purchase something now if I will inherit the ability to refund later? If not, I see no benefit in keeping them and would rather take the refund.

I only ask this because there has been a warning on the refund page stating that you will "lose the benefits associated with the voucher should you choose to receive a cash refund." I was never certain what they were suggesting.
