In 2018, we announced the selection of the Airbus A220 aircraft as the replacement for our existing Embraer 190 aircraft. This selection of a new aircraft before the full useful life of older aircraft had expired was driven in part by our fuel and greenhouse gas emissions efficiency strategy. It is highly unusual for an airline to replace its entire fleet halfway through its expected lifespan, but the improved fuel efficiency and cost savings made this the clear choice. This asset shift brings the potential of an estimated 40% fuel efficiency improvement per seat and an equivalent reduction in carbon emissions, contributing to an estimated 30% decrease in operating cost per seat.
