Iberia has announced a special promotion on the front page of its British website.

Few details are provided, but you must book a paid Iberia flight before 15 May, 2018 in order to qualify.

Which flights qualify? Good question… In my experience, this promotion should cover:

• Flights on Iberia / Iberia Express metal
• Codeshare flights booked with an Iberia flight code

Although it isn’t specified, I believe that you probably need to book on iberia.com, not via an online travel agency (or corporate travel agency). In addition, I would expect that only base miles are doubled, not any cabin or status bonuses. The base miles earned on cheap economy fares are:

• 100% for Y/B/H
• 50% for K/M/L/F/V/S/Z/N/G
• 25% for Q/O/A

Don’t forget to visit Topcashback first, as you can earn £3.53 for most short haul flights (more for long hauls).

If a landing page / T&Cs for the promotion is ever provided, I’ll edit this post to add the link. But, for now, you’ll just have to trust Iberia’s front page marketing…
