WestJet Airlines Ltd. provided operational guidance for the year 2019. For the year, RASM is expected to be in the range of up 2.0% to 4.0% year over year driven by solid demand and strength in the core WestJet business, the roll-out of branded fares across all WestJet operated routes, the increase in WestJet's first bag fee, Swoop ancillary per traveler increasing to $40, and the introduction of premium and business cabins on the Boeing 787 Dreamliner, offset by capacity increases in Swoop which have a dilutive effect on overall RASM performance. For the full year of 2019, CASM, excluding fuel and employee profit share is expected to be flat to up 2.0% year over year driven by continued investment in the business to support the Boeing 787 Dreamliner and the infrastructure required to deliver on WestJet's strategic plan and capacity increases in Swoop which have a dilutive effect on overall CASM performance. In 2019, the company continues to expect system-wide capacity growth of between 6.5% and 8.5% and domestic capacity growth of between 1.0% and 3.0% Growth in 2019 is attributed to the launch of transatlantic service on the airline's new Boeing 787 Dreamliner and the incremental capacity associated with Swoop increasing to ten aircraft.
