Air Canada will add South Carolina to its route map and fly from Montreal to St. Louis and Austin.
Daily year-round service to Charleston from Toronto will launch March 28. Air Canada will be the only airline flying from Canada to South Carolina's Low Country.
Air Canada will fly four times per week between Montreal and Austin beginning May 2. Daily summer seasonal flights between Montreal and St. Louis will commence May 1. Air Canada is the only airline scheduled to fly those city pairs.
Air Canada already serves St. Louis and Austin from Toronto.
Air Canada said it hasn't finalized its North American schedule for next summer and can't yet comment on whether it will discontinue any U.S.-Canada routes.
"Our overall plan for summer 2024 calls for an increase in North America and Caribbean seat capacity from 2023," said a spokesperson.
