The point you're missing is that under our system of laws, if it's not explicitly against the law, then it's legal.
You say they're not allowed to, but there's also nothing which expressly prohibits the DOJ from doing what they're doing.
except that the airline deregulation act SPECIFICALLY prohibits the US government or any local or state government from making any decision that inhibits the ability of the free market to decide what level of service and at what price.
The DOJ arbitrarily chose to define DAL and DFW as the same market so as to define that LFCs are disadvantaged but did not use the same definition for NYC and WAS because if they did there could be no argument that WN or Virgin could get preferential access based on WN's BWI hub or B6's JFK hub.
further, there are indeed airport access laws which require federally funded airports to provide access to new entrants. DL is not a new entrant at DAL but it will be if it cannot be accommodated.
swamt,
you have repeatedly tried to argue just like your company is doing that WN is the best choice for further DAL gates. No one in their right mind could honestly believe that any government would give WN even more gates than they already have at DAL and you and WN refuse to acknowledge that the lease that has WN's signature on it REQUIRES them to accommodate new entrants.
you can rely on the DOJ's involvement in the case as justification but it isn't legal and won't stand if it is challenged... and it is indeed all but certain that someone will sue because the whole deal is certain to tick someone off.
And it is far from clear that it will be Delta who will be screwed because the whole deal is based on an agreement with Virgin and AA driven by the DOJ, which is not above the law which it didn't understand.
A city councilman and Virgin both said the study was flawed. And it still doesn't matter what the study says. Airport access rules and WN's 2006 contract require other carriers to be accommodated. WN does not have the ability at this point to decide to negate the very contract that is giving it the right to fly longhaul domestic flights from DAL in the first place.
AA and DL would be more than happy to toss the whole agreement and keep WN in their little box at DAL if WN wants to start carving out parts of the agreement it doesn't like but previously agreed to.
We can keep this up for weeks until it is resolved but it is very, very possible that WN will not be allowed to expand or will be forced to allocate space necessary to accommodate any new entrants including perhaps BOTH Virgin and Delta and anyone else that might want to show up.
