For the first time ever you can soon fly non-stop to Nashville, Charleston and Raleigh Durham from Seattle. Service will begin this fall and you have until Monday, May 4th, to buy tickets at the special introductory one-way rate.
All the detailed information can be found here.
This is really great news if you live in Seattle. Alaska Airlines will be probably anyway the airline of your choice. I flew them a lot lately and if I had problems they all got solved to my satisfaction.
