An Alaska Airlines jet bumped another jet at the gate shortly after 7 a.m. Wednesday as it was leaving Seattle-Tacoma International Airport.

A flight leaving for Dallas was pushing back from the terminal when the tip of its right wing struck the left rear tail of an empty Alaska Airlines jet that had been scheduled to fly to Minneapolis, according to Sea-Tac spokesman Perry Cooper. The empty jet was still at the gate.

There were no injuries, and passengers were taken off the Dallas-bound plane and returned to the terminal.

Bobbie Egan, spokeswoman for Alaska Airlines, said the airline is investigating the accident and assessing the damage to the airplanes.

She said both were taken out of service.
