Update....SWA to PAE..

A year ago, no airline offered regular commercial passenger flights from Paine Field in Everett, Wash. By the end of the year, there will be three.
Southwest Airlines became the third carrier to announce its intention to fly from the airport, further solidifying momentum for establishing Paine Field as a “secondary” airport for the Seattle metro area.
Alaska Airlines and United Airlines have already announced their own plans to fly from Everett, where a new two-gate passenger terminal is now under construction to handle the service.


Though Paine Field is home to Boeing’s adjacent widebody assembly line and to some general aviation flights, it has been decades since the airport last had regular commercial passenger service.
Southwest revealed its plans for Everett in an interview with The Seattle Times, telling the paper it will begin a schedule of five daily round-trip flights on Boeing 737s once the new terminal opens this fall. Southwest said it would reveal its destinations from Everett later this year. (Full report: The Seattle Times)
“We’ve wanted to grow in the Seattle metro market for quite some time. But Sea-Tac airport is constrained,” Southwest CEO Gary Kelly said to the Times. “Paine Field will be a wonderful alternative for our customers.”

Constrained....Hummmmm. Is that code for AS and DL "Run the City"?
