I got the e-mail and have a spare current account which I don't use. It has a few £'000 credit balance but no DDs. I don't mind using the "full switch" to close that account, and can route £50k from my main operating account, in and out through the new Barclays a/c. I could also move a couple of DDs to the new a/c. I would plan to keep it open for (say) 6 months, or maybe close it once the 25k Avios have been credited. Any problem with this plan ?
