You can read much more about this elsewhere, but in case you didn’t see it (if you’re reading this site, though, you probably have seen it. I’ll shut up now) Delta rejected US Airways’ buyout offer. The most interesting reason given by Delta is that the merger would create monopoly power on 2,000 city pairs. I would think this would be a good thing for an airline, as they could increase fares, but they’re saying that the merger would never pass Department of Justice scrutiny. Look for US Airways to increase their offer, only to be rebuffed again. My guess? Delta will ultimately stay independent.
