The round trip (YYZ <-> RGN) was cancelled by Air Canada in 2020 due to covid and they issued credits that allow name changes as well as origin/destination/transit changes. The credits are very flexible to use since AC updated their policy this year. The credits are valid for one person only! If you’re an international student who needs to travel long connecting flights. back to school or home, I assure you this offer is really affordable and convenient!
