I've said it before, I'll say it again - IMO BA Club Europe is far better than Iberia Business.

In economy, I like that fact that in IB Y you can BOB if really hungry, far more helpful to me than BA EuroTravller minimums. Ideal would be a combination, basics free (comensurate with length) then BOB on top.

And, give you my distain for Iberia Business, let me say other than Tier Points, I would rather fly Iberia economy ahead of Iberia Business class any day. In Economy the Iberia cabin crew are polite and friendly, in Business they are not. [This is not a 'cultural difference', I've not seen it elsewhere in Spain, it is Iberia crew - the treat you as an equal human being in Y, in business they treat you with distain. Plenty of IB sectors to back this up.]
