Feel free to renounce your citizenship... There's a chance you won't be missed.
You don't like the fact that the DOJ are standing in DL's way of abusing their market position, but that's their job. They most certainly do have the right to prevent oligopolies, and what they've done in managing the DCA and LGA slot divestitures clearly supports that.
You're hopelessly hung up on the low fare aspect that these airlines have in common, and ignoring the fact that the carriers selected are the most likely to continue to offer some form of competitive pressure on the larger three airlines, although I do question if VX is going to remain in business long enough to really matter...
You are the only person I've seen who is thumping on the table and questioning DOJ's authority on this.
At some point, you might want to consider why that's the case. Perhaps all those well paid lawyers on staff at DL realise there's no basis for trying to do so, and even less chance of actually overturning those decisions.
