Our first transfer bonus will be Chase to Avios 20%. Now first with Iberia you can get business class from SFO for 51k.
Also Iberia has some deals that can take you to Spain for 6.4k to 8k in economy. Now BA do not book because there are better options like American or Aer Lingus to avoid surcharges. If you want to fly BA metal we recommend you use Cathay or JAL. You can also do Qatar Q-Suite which is one of the best ever for 70k Avios.
Now for I Prefer it is 30% from Capital One. Even with this 30% it is still 1:2.6 not 1:4 like Citi so do not transfer. That is all for today.
