Turbulence caused 14 passengers on a flight from Vancouver to Edmonton to become ill.

Aeroinside.com reports that the Flair Airlines Boeing 737-400 was climbing out of Vancouver on Dec. 29 when, while on autopilot, the aircraft pitched up sharply by 20 degrees and rolled 45 degrees to the right.

The autopilot applied full left aileron, causing the aircraft to then roll 30 degrees to the left.

Significant buffeting continued after the airliner levelled off.

The fasten seatbelt signs were illuminated during the incident, and passengers were instructed to remain seated, but the Transportation Safety Board reports 14 people did become ill. There were no injuries, however.

The aircraft continued to Edmonton for a safe landing.
