Turbulence during a WestJet flight to Winnipeg from Calgary caused injuries to four people, officials said Saturday.

A spokeswoman for the Winnipeg Airports Authority, Christine Alongi, said the plane landed safely on schedule about 2:30 p.m. CT.

Two of the injured were flight attendants, the other two passengers, Alongi said.

While medical attention was needed — medical personnel were called to meet the plane when it landed — Alongi could not describe the nature of the injuries.
