Since an ellipsis is supposed to have spaces

I have never previously heard of spaces between the full-stops in an ellipsis.
More an issue is the writing of run-on sentences by stringing clauses together with ellipses in between. These should be replaced where possible by full and stand-alone sentences.
(But this is getting rapidly off-topic.)
To the original question, BA's policy is that unless exempt by travel class or status, you can't be over 23kg on any individual bag, even if you're over on another. In many locations where it operates, bags weighing 23-32kg must be handled by two people, and they apply the charge to disincentivize this.
