The past year sure has been an interesting one for Alaska and Delta in Seattle. For those of you not familiar with the “battle in Seattle” that has been going on for Alaska and Delta…
It got serious in 2012 when Delta announced huge international expansion out of Seattle, which Alaska was justifiably excited about, since they were being tapped to provide the feed for that international service.
But it seems Delta had a bit of an epiphany, and said “hmm, why should we be outsourcing all this domestic flying to Alaska, when we could do it on our own?” So they’ve announced huge domestic expansion, and at this point are serving almost all of the major routes that Alaska does as well.

To get back at Delta a little bit, Alaska announced additional expansion in Salt Lake City, with additional nonstop service from Salt Lake City to four destinations, including Portland, Los Angeles, San Diego and San Jose. Obviously they’re a much smaller airline so can’t “retaliate” nearly as much.
Meanwhile both airlines have been offering tons of promotions, and Delta is even offering Washington residents double redeemable and Medallion Qualifying Miles for flights out of Seattle for the remainder of the year.
This raises the question, when will their “partnership” stop? I mean, seriously, this would be no different than British Airways and Virgin Atlantic or Qantas and Virgin Australia partnering.
They’re undercutting one another and offering promotions to lure flyers from one another, all while still proudly boasting that they’re partners and offering miles for travel on the other airline. Don’t get me wrong, as a consumer I love this dirty competition, but I almost feel bad…
Admittedly they probably have a contract, but surely they can mutually terminate it, no?
