Iberia Plus has launched 40% off economy and business award sale for travel March 1 – June 19, 2016, that must be booked by February 29.
The offer is valid on 50 routes (Iberia has not published a list) that includes European capitals, Canary islands and Latin America.
You can access Iberia’s website here.
I cannot find a landing page on Iberia’s website for this offer that is not a surprise how confusing and illogical it is. These award discount should already show up on the award searches that you do on their website, however.
