One way to accomplish this is to purchase some Avios, which also triggers a tax reduction on intra-Europe award redemption. Depending on the number of tickets you are redeeming, you might come out ahead on the purchase of Avios.
Hi -- can you explain the tax reduction on the intra-Europe award redemption? I have an active IB account that I've used for redemptions and also has miles in it. I am able to transfer BA avios to it. Is there anything else I need to do to see this "tax reduction"? Presently, if I search for an intra-Europe award on either BA or IB, I get the same Avios points requirement and the same tax (as opposed to transatlantic, in which case IB is better on tax). Are you saying the intra-Europe tax rate will be better if I buy 1,000 IB Avios in my IB account?
