Hi all. Is it true that it's only possible to book return flights on Avianca when using Iberia Plus Avios? I'm after SJO-BOG, and they're asking for 51,000 avios + €288 tax total for three pax. Ignoring the fact that 51,000 doesn't divide evenly into any of the points listed on the Iberia-Avianca redemption chart, I'd be better off booking cash one-way flights at that price.
Has anyone had any luck booking just one way?
