However there is always the possibility of an aircraft change, to a 787-9 for example (none of BA's -9s have Club Suites yet - and the fitment programme for them won't start until next year). It could happen as a planned schedule change or simply happen on the day due to a lack of serviceable 787-10s. I haven't checked the details but it may be that the new MIA frequency is reliant on additional 787-10s being delivered. These are of course notoriously delayed.

BA also does not allow you to change your flight merely due to an aircraft change, even if that means a change from Club Suites to the "old" Club World seat. You would need a cancellation or (sufficiently large) schedule change for that to be the case.

So if having a new product matters to you, I can only recommend sticking with Iberia. But if you're willing to take a chance then book onto BA.
