SPOKANE INTERNATIONAL AIRPORT, Wash. -

A passenger onboard an Alaska Airlines flight from Washington, DC to Seattle experienced a medical emergency, requiring the flight to be diverted to Spokane Friday morning.

Alaska Airlines Flight 1, flying from Reagan International Airport to Seattle-Tacoma International was approximately an hour into its flight when, according to an eyewitness, flight attendants began walking around the cabin anxiously. A woman onboard the flight was unresponsive. A doctor happened to be onboard the aircraft and was able to assist.

Around the Montana / Idaho border the woman's condition became critical, and the flight crew decided to divert to Spokane International Airport.

The aircraft touched down at Spokane International and the woman was transported to a local hospital. Her condition is not known.

The aircraft departed again at 11:49 a.m., scheduled to arrive about two and a half hours behind schedule.

The eyewitness said he was impressed with the Alaska flight crew, who kept passengers informed of the situation and remained helpful during the emergency.
