Delta Air Lines is using the IATA Winter Season, which runs from late October to late March, to add seven international routes to its network. The additions span six of the carrier’s US hubs, ranging from a short cross-border hop to long-haul corridors. None of them include the airline’s short-term CES additions. Together, these routes cover 13 airports. The list shows where Delta sees demand growing and where it is defending its position against rival carriers.
Los Angeles to Vancouver Launches First in November
The first launch arrives in November, when Delta will fly between Los Angeles International Airport (LAX) and Vancouver International Airport (YVR) in British Columbia. Starting November 21, the airline will operate this short-haul transborder route twice daily using Airbus A319s from its mainline fleet. Delta has served this corridor on and off for two decades, with regional Delta Connection flights in 2007 and 2008, followed by a return from 2015 to 2018. Mainline jets last flew it in 2017. LAX has since become one of Delta’s most important bases, and the airline describes itself as the only carrier at LAX serving all of the airport’s top 10 markets with multiple daily flights.
Three December Debuts: Atlanta–Tel Aviv, JFK–Liberia, and Detroit–Aruba
December 19 brings three launches on a single day. The longest is Delta’s return to Israel, with three-weekly flights between Hartsfield-Jackson Atlanta International Airport (ATL) and Ben Gurion Airport (TLV) in Tel Aviv, operated with the Airbus A350. Delta last flew this corridor from 2006 to 2011 and again in 2023. The same day, the airline starts John F. Kennedy International Airport (JFK) to Daniel Oduber Quirós International Airport (LIR) in Liberia, Costa Rica, using the A321neo. That service runs seasonally until May 2027, after earlier stints in 2008 and from 2013 to 2017. Detroit Metropolitan Wayne County Airport (DTW) to Queen Beatrix International Airport (AUA) in Oranjestad, Aruba, supplies the only genuinely new entry: weekly seasonal flights until May 2027, split between the A321neo and the Boeing 737-900ER, on a route Delta has never flown.
A Trio of March Debutants Closes the Season
Delta saves its final three additions for March 27, the last day of the winter season, and all three are long-haul. From Seattle-Tacoma International Airport (SEA), daily service to Tokyo Narita Airport (NRT) is a direct response to growing competition from Alaska Airlines in the Northwest. The A330-900neo will operate that route, and the same aircraft will fly daily between Austin-Bergstrom International Airport (AUS) and Paris Charles de Gaulle Airport (CDG). March 27 is also the current launch date for thrice-weekly Atlanta–Riyadh (RUH) flights, though that service has sold poorly and has been delayed.
The Airports Behind Delta’s Winter 2026–27 Route Push
The hubs anchoring the expansion make a clear strategic statement. Atlanta takes two additions, the premium Tel Aviv return and the contested Riyadh link. Los Angeles takes the Vancouver shuttle. New York gains the Costa Rica gateway, while Detroit and Seattle each receive one route. Austin’s Paris flight extends the carrier’s Texas footprint into a major European hub.
What the Winter Schedule Tells Delta Passengers
The winter schedule captures the 7 new routes, 13 airports, and 29,034 network miles behind Delta’s strategy. Existing travelers benefit immediately. The Los Angeles–Vancouver launch restores a twice-daily option that frequent flyers have missed since 2018, while Detroit–Aruba adds a winter-sun option that Delta has never offered before. Long-haul upgrades favor Seattle and Austin, whose Tokyo Narita and Paris routes use the A330-900neo. Travelers who book early will also find rare seasonal windows for Liberia and Aruba, and Atlanta’s Tel Aviv return revives a corridor that has historically been popular with business and diaspora traffic.
