As can been seen on the photo in this update -
https://www.westjet.com/en-ca/news/2...service-update, the remediation work for the hail damage is going to be extensive. The trailing edge flaps and the spoilers are particularly badly affected, some panels may be completely replaced, but others will require rivets to be drilled out and sealant removed to swap the skin. Overall a very labour intensive process from both a replacement and quality assurance perspective.
i wouldn’t expect they can have all 16 aircraft that sustained this level of damage back in service before year-end.
