We started our trip by flying from Toronto to Calgary, had a 2 hour lay over then boarded Delta Airlines to fly to Seattle. We had a slight issue with our tickets in Toronto as they were purchased using West Jet dollars, points and cash. Once the West Jet employee managed to connect our 2 tickets, boarding passes and luggage tags were printed and we were on our way. In Calgary our bags were taken directly to the Delta plane and we had a great flight to Seattle. Both co-operators were extremely friendly, helpful and a pleasure to fly with.
