Delta’s transatlantic route network is evolving in an interesting way. While the airline might be launching flights to Malta and Sardinia, it’s pulling out of a major business market, in which it’s seemingly unable to compete.
Delta discontinuing flights to Geneva, Switzerland
Delta currently operates a summer seasonal flight between New York (JFK) and Geneva (GVA), which is the carrier’s only service to the city. Unfortunately it appears that this is coming to an end.
The current seasonal service will operate through October 20, 2025, though the flight has now been pulled from the schedule for next summer, as noted by @IshrionA. That means that based on current schedule filings, the airline will no longer fly to the airport at all.
The 3,863-mile seasonal flight is currently operated with the following schedule, using a Boeing 767-400ER:
DL100 New York to Geneva departing 8:50PM arriving 10:45AM (+1 day)
DL99 Geneva to New York departing 12:45PM arriving 3:30PM
Interestingly, Delta didn’t actually serve Geneva for many years, and only operated the route seasonally again starting in the summer of 2023. So the service will have lasted three summers, prior to being cut.
This latest route cut follows Delta’s recent decision to cancel its New York to Brussels (BRU) flight, instead choosing to shift the route to operating out of its Atlanta (ATL) mega hub.

Is Delta ending New York to Geneva service surprising?
Personally, I’m not surprised to see Delta pulling out of Geneva. I mean, the airline wasn’t actually really trying to compete in the market, given that the service has only been operated as a summer seasonal flight. You’d think that Geneva would be served as a year-round business route, rather than a summer seasonal route.
But of course this gets at a bigger issue — Delta really struggles in markets that are dominated by Lufthansa Group carriers, and for good reason. That’s not too surprising, as most of the hubs are business markets rather than leisure markets, and that makes it tougher to compete with the dominant carrier.
SWISS flies year-round between New York and Geneva, and of course Lufthansa Group carriers (plus United) have excellent connectivity between all points in the United States and Geneva. So no, I’m not surprised to see a summer seasonal route like this cut.
At the same time, it’s interesting to consider the bigger picture here. Delta is the largest airline in New York, and it likes to think of itself as the premium airline for business travelers. Nowadays airline route networks aren’t just about the profitability of each individual route, but they’re also about the overall portfolio of service you can offer, in an effort to generate credit card loyalty, secure corporate contracts, etc.
Last year we saw Delta axe its New York to Munich (MUC) route. Then we’ve just seen Delta cut its New York to Brussels route. Now we’re seeing the airline cut its New York to Geneva route. One would certainly assume that the days for the New York to Frankfurt (FRA) route are numbered as well, no?

As I said when the New York to Brussels route was cut, the way Delta positions itself at its New York hub continues to puzzle me. For example, it’s funny how despite Delta’s huge network there, the carrier chooses not to fly to Asia, even when it had the chance to.
In early 2024, the Department of Transportation (DOT) could award a US airline extra Tokyo Haneda (HND) slots, and airlines could make their proposals. You’d think that Delta would’ve expressed interest in New York to Tokyo, but it didn’t. Instead, American is flying the route (which… is something).

Bottom line
Delta will be cutting its seasonal New York to Geneva route, meaning the airline will no longer fly to this important city in Switzerland. In isolation, I wouldn’t think much of it, but it’s interesting to see Delta also cutting flights from New York to Munich and Brussels.
Despite its strong position in New York, Delta seemingly can’t compete in Lufthansa Group hubs. Then again, that’s not surprising when you’re serving what’s ostensibly a business market with a summer seasonal service. I’m just curious when the New York to Frankfurt flight gets cut…
What do you make of Delta cutting New York to Geneva flights?
