WestJet says it could be several more weeks before its entire fleet is back in service.

The airline says sourcing specialized equipment and materials and completing repairs will take several weeks.

An average of 50 flights per day are currently being cancelled, but the airline anticipates fewer cancellations as aircraft are returned to service in a phased approach.
