I don’t think there’s really much to take advantage of.

I’d save the hassle and buy 15,000 Avios off groupon.es for €189. If you do it via the Iberia Plu Store you’ll get another 2457 Avios, so 17,457 Avios for £173, only takes 5 minutes and will land in your account in 2 weeks.

Buy it on your Lloyds card to avoid getting stung on the € to £ conversion.
