Hi - Apologies if a stupid question but trying to book London Heathrow - Vancouver flights using a companion voucher. There doesn't seem to be any availability until November. Would that be because they have all be taken already or not yet released? We would like to fly Premium Economy in August or September.
Also I believe I can now use the companion voucher on Aer Lingus. Where can I search to find the availability using the companion voucher with them instead?
