except that the basis of DL's interest in AS was to feed DL's international operations on the west coast. NW had a longstanding relationship with AS that involved feeding NW's int'l ops at SEA.
Do you happen to recall that DL execs went out to SEA to put on a great PR stunt with AS regarding a deepened relationship and closer cooperation not that long ago and within a couple weeks, AS announced the same type of expanded agreement with AA
DL also said multiple times even publicly that DL was not going to be in a partnership with a carrier that was providing feed to any of DL's competitors and yet that is exactly what AS has done
They are a codeshare whore that wants to have as many partners as possible and yet couldn't provide DL, their largest partner, with enough seats to support DL's int'l operations.
DL had no choice based on AS' actions but to start its own SEA domestic operation.
AS has no one to blame except themselves for now having a major competitive hub in its home.
The ship has sailed and AS' actions have resulted in a significant change in their strategic future and a very likely rearrangement of market strength on the west coast.
All AS had to do was provide DL with the feed DL wanted to support its own int'l flights which didn't compete with AS.
DOT data supports DL's public statements that DL's int'l operation at SEA has largely been supported by DL's own domestic flights and the local market.
IN order to grow the int'l operation further, DL has made the irrevocable decision to add its own domestic flights including into key west coast markets north of SEA such as to Alaska and Vancouver that are less about feeding the int'l operation and more about operating a balanced hub.
And it also doesn't change that as much as the internet crowd wants to argue otherwise, AA can offer nothing more to AS or vice versa that they can't already do or that AS couldn't have had with DL.
And no one has addressed that AA's pilots want less, not more cooperation with AA's domestic codeshare partners.
DL has one of the fastest growing hubs at SEA among all US carrier hubs and the movement of DL's mainline fleet to the west coast will only ensure that the number of DL seats at SEA will continue to grow.
AS' decision to be a codeshare whore will likely go down as one of the biggest strategic failures a niche airline could have made.... and as E has noted there are few of those niche airlines left.
