Friday, August 18, 2006 Alaska Airlines flight diverted to Seattle An Alaska Airlines flight had to make an unscheduled stop in Seattle Friday morning after the plane lost cabin pressure, according to Sea-Tac Airport spokesman Bob Parker. Parker says Flight 690 left Vancouver, B.C. just after 7 a.m. and was heading to San Francisco when the Boeing 737 lost cabin pressure. The plane was diverted to Seattle and landed safely around 8:20 a.m. Fourteen people, including at least three crew members, were being treated by Sea-Tac medics for very minor injuries, Parker said.
