WestJet offers refunds to passengers with cancelled European flights However, an email on Sept. 13 threw a wrench in their plans.Nilsson says they were told WestJet had to cancel the flight and the airline could not provide any alternatives.“They reopened these flights and then they realized there wasn’t enough demand for them.“It was a demand issue based on their miscalculations on what demands would be like on these flights.” Canadian airlines cancel hundreds of flights as hopes fade for spike in demand Because travel is so uncertain and tedious during the COVID-19 crisis, Nilsson understood that circumstances could change.“Honestly, we have no problem that it was cancelled, that’s just some of the risk that we took with booking.
