BAA Break-up

I’m kinda undecided on the BAA break-up. The FT thinks it should definitely go ahead. But as a fairly strict libertarian, and therefore keen on economic freedom, I’ve always had a problem with monopoly break-up except in the most extreme of cases (and I’m not sure this qualifies). Nevertheless, as my job now takes me onto an aeroplane more than I before, I’m curious and so I read the summary from the Competition Commission’s provisional report.
