Wah,wah, wah. Don't blame me because Delta is about to be subjected to an involuntary fornication situation.
DL/US have changed the rules and made the rules since this whole thing was announced and WN wanted in. You both(DL/US) couldn't care less about 'people's benefit' and we all know it's about Tempe and Datlanta's bottom line.
and you somehow think that WN isn't interested in their own bottom line? of course they are. And they darn well better be.
.
DL and US created a deal that adds value to both companies by transferring assets that were underutilized. Despite lots of calls for the end of slots, the US to reposses all slots, etc... the Feds have taken the approach that the slots remain private property of the airlines... their only intent and their only action was to require that a certain amount of the slots be given to competitors that can check the potential for a carrier to hold 50% of the slots at an airport at which other airports cannot freely enter.
It's no different than what was required of AA/BA at LHR, resulting in a slot divestiture that DL chose to benefit from... but the slots remain AA/BA's, DL must pay rent for those slots to AA/BA, and other new entrant carriers - US, DL, CO, NW included, did not get all they wanted.
.
This slot swap is no different. There will be some nit picking over the details but AA/BA will remain dominant at LHR; DL will remain dominant at LGA; US will remain dominant at DCA.... until others are willing to spend the money to buy the assets that AA/BA, DL, or US have used to build their market positions, the rest of the industry will have to make do w/ what they have.
The only crying is and will be by those who didn't have the forethought to win in a competitive and limited access situation.
.
Just to be clear, using the slots WN already has as a result of the merger w/ FL, they could offer enough seats to be the #3 carrier in each of the three airports - EWR, LGA, and DCA - if they upgraded all of their flights to their future 738s. If they gain 8 more slots each at DCA and LGA, highly likely since they can outbid just about anyone, they could be in a position to have half the seats AA has at LGA - the current #2 which won't change w/ the slot deal and #3 behind DL at DCA; although it is hard to know what DL will do at DCA after the slot deal.
.
Bottom line is that WN is in very good position at DCA and LGA as well as EWR already and the slot deal will only add even more seats.
Considering that WN didn't even serve LGA, DCA, or EWR until a few years ago, they have done pretty good and it will likely be good enough for them to bump one of the other network carriers in ranking in the next few years.
