Absolutely, my vouchers will expire if they dont take them for that flight. I have full understanding they just dont clear them month before but 2 weeks or so they should because there aren't so many bookings in First on the last day or so. and the Airport experience is a important part. I do understand they try to sell those for cash but if I have vouchers they should be equivalent to upgrade bids because they are just useless if not. Interesting is that upgrades for a flight in 12 months i get for 4 persons! I cant understand that but hope the waitlist will clear a few days before flight.
