Canada's WestJet and Delta Air Lines have upgraded their interline agreement formed last year to a full-blown codeshare, allowing Delta to broaden its reach in Canada.
The carriers officially kick-off their new codeshare on 23 January when they roll out the first phase entailing Delta placing its codes on more than 15 WestJet flights and the low-cost carrier placing its code on Delta flights in five markets - four from its Detroit hub and one from Boston.
SkyTeam anchor carrier Delta is placing its code on 10 WestJet flights from Toronto, including the popular business route to Ottawa, seven from Calgary, three from Vancouver and a single flight each from Winnipeg and Halifax.
Schedules in the Innovata database show that Delta currently offers nonstop flights from Minneapolis and Salt Lake City to Vancouver, nonstop service from Minneapolis to Calgary and nonstop flights from New York LaGuardia and Detroit to Toronto.
The second phase of the relationship could include a broader push from New York LaGuardia where Delta is building a hub and WestJet recently won eight slot pairs in an auction required for Delta and US Airways to trade slots at LaGuardia and Washington National airports.
WestJet also codeshares with Oneworld carrier American Airlines while Canada's flag carrier Air Canada is a member of the Star Alliance.
