I have a question regarding voucher validity that I can't find the answer to...
So I just qualified for AY Plat and therefore got 2 LH and 4 SH vouchers (likely to be used as one LH for me). Is the expiry date for use of the voucher or for flying?
I hope it is to apply the voucher as else it is rather useless to get a hoard of upgrade vouchers with 10 days to go... [And my only booked AY flights in that time span is in C anyway]
