There are a number of bugs in the system and no money is being spent to fix them, they seem to rely on the chat agents to do resolve problems. That said, given the Vueling is essentially a Low Cost Carrier, and uses Avios purely on an alternative revenue method, rather than redemption basis, it's not usually fruitful use of Avios.

For the Iberia / BA match, I'd imagine there is some creative way to live without a hyphen on both accounts? I can't see any real postal transaction happening in this space?
