YYZ recently launched an education campaign on 13JUL with two infographics designed to help passengers become part of the solution to wait times at the airport. Infographics included “A better trip through Pearson,” which walks passengers through Pearson airport and provided simple tips and tricks to help smooth journeys, as well as “Solving for congestion at Pearson,” which walks through the steps airport partners and government stakeholders have taken to improve passenger flow through Pearson, and what’s next as industry works to smooth the process of flying into and out of Pearson.
In addition, Air Canada introduced a flexible policy 19JUL which specifically targeted YYZ "due to longer than usual delays." The policy allows fee-free ticket changes (subject to availability) either to let pax switch flights to YTZ or to extend connection times at YYZ.
