The Swiss airline Swiss International Air Lines (Swiss) has announced that it will reduce its long-haul flights during the summer months of 2025. This decision particularly affects the connection between Zurich and Chicago, two important international hubs.
The airline will reduce its number of flights on this route from March to June 2025, resulting in a reduction in available seats. In addition to cutting flights to Chicago, Swiss also plans to reduce flights to Shanghai, Boston, and Dubai, which will have additional impacts on its passenger volumes and international flight schedule.
Fewer flights between Zurich and Chicago
According to aviation analytics firm Cirium, Swiss will significantly reduce the number of flights on the Zurich-Chicago route from March to June 2025. For example, only 2025 flights are planned for April 43, instead of the originally planned 60. For May 2025, there will be only 44 flights, instead of the originally planned 62. For June 2025, only 43 flights are also planned, instead of the originally planned 60. These reductions will result in a total of 12.272 seats being removed from the schedule from April to June 2025. This could impact passengers who regularly use this route, particularly business travelers and tourists who prefer the direct non-stop flight between Zurich and Chicago.
However, starting in July 2025, the flight schedule will return to the originally planned frequency of 62 flights per month. Swiss and United Airlines are currently the only airlines offering nonstop flights between Zurich and Chicago, making this connection particularly important.
The aircraft used on this route are primarily Airbus A330-300s and Boeing 777-300ERs. The Boeing 777-300ER offers more capacity and premium seating than the Airbus A330-300 and can accommodate up to 320 passengers in a four-class configuration. The Airbus A330-300, on the other hand, can accommodate up to 236 passengers in a three-class configuration.
Further cuts in the summer flight schedule
In addition to reducing flights to Chicago, Swiss is also planning cuts on other long-haul routes. One of the affected routes is the connection from Zurich to Shanghai Pudong, which will also be less frequented from April to June 2025. Swiss is the only airline offering a direct connection between Zurich and Shanghai and uses its Airbus A340s on this route. The reduction in flights on this route therefore represents a further restriction in the airline's international flight network.
In addition, connections between Zurich and Boston and Zurich and Dubai will also be reduced. On the Zurich-Boston route, the number of flights will be reduced from 24 to 6 weekly connections between May 2025 and June 14, 12. On the Zurich-Dubai route, the frequency will be reduced from seven to six weekly flights, which will also impact passenger capacity.
Background of the reductions
Swiss's decision to reduce its flight frequency could be related to several factors. On the one hand, the global aviation industry is still struggling with the aftermath of the pandemic, which has led to reduced passenger volumes and higher operating costs. On the other hand, the airline could also be reacting to potentially weaker demand in the affected markets. Economically uncertain regions and geopolitical tensions could be particularly affected, negatively impacting travel.
The reductions primarily affect the summer months, which traditionally see higher demand for international flights. However, the flight schedule is expected to stabilize in the second half of the year, indicating a return to normal frequencies and capacities.
Long-term effects and passenger reactions
Although the reductions are temporary and the airline plans to return to normal in July 2025, the changes could be inconvenient for passengers who rely on regular connections. Business travelers and tourists flying from Zurich to North America or Asia, in particular, may have difficulty rebooking their flights to the new times and frequencies. Passenger numbers on the affected routes could also decline, which could further impact Swiss's revenue.
Passengers could expect better communication and support from the airline in the future when rebooking their flights. The upcoming 2025 summer schedule will therefore also be an opportunity for Swiss to demonstrate its flexibility and customer satisfaction.
