Dee used the analogy of a giant scattered jigsaw puzzle to explain the disruption whereby WestJet must reassemble numerous disrupted components and routes. "They now have a bunch of pieces that don't fit together that they have to reassemble, so they've got to get that jigsaw puzzle back together. It's going to take some time to do that." Dee lauded WestJet's proactive measures to avoid a major disruption, contrasting it with the ordeal faced by Southwest Airlines in December when a winter storm led to nearly 17,000 flight cancellations.
