Card needed once vouchers on account.
I've had 2 years from this now and burnt a truck load of Avios and 2 upgrade vouchers, another 2 vouchers have just landed on my account.
I'm winding down my BA flying, have plenty of Avios and 2 vouchers valid until March 26 (earliest), which coincides with my Silver expiring.
I only got the card and current account for this so will be closing both. My question is whether I need to retain the card (or free version) until I've used the vouchers or if I can just close it down?
