SWISS Cancels 1,400 Summer Flights Causing Seat Shortages

Key Takeaways

• SWISS cancels 1,400 flights from April to October 2025 due to pilot shortages and fleet issues.
• Zurich–Chicago flights drop by 50% in September–October; up to 50,000 UK passengers affected.
• Affected passengers can rebook, get refunds, or receive compensation under EU261 passenger rights.

Swiss International Air Lines (SWISS) has announced the cancellation of 1,400 flights for the busy summer 2025 travel season, sending shockwaves through the aviation world and leaving thousands of passengers scrambling to secure alternative seats. The cancellations, which affect both short-haul and long-haul routes—including the popular Zurich–Chicago and Zurich–Shanghai services—will take place between April and October 2025. This move, representing about 1.5% of SWISS’s scheduled departures, is a direct response to a complex mix of pilot shortages, fleet issues, and new labor agreements. The impact will be felt not only by travelers but also by the broader airline industry, with ripple effects expected across Europe and North America.

What Happened: The Scope and Timing of SWISS’s Flight Cancellations

SWISS, a subsidiary of the Lufthansa Group, made the announcement during the last week of May 2025. The airline confirmed that 1,400 flights would be cut from its summer schedule, affecting both European and intercontinental routes. The most notable changes include a significant reduction in the frequency of the Zurich–Chicago and Zurich–Shanghai flights, with the Zurich–Chicago route seeing its service halved in September and October 2025.

On a daily basis, this means 10–15 flights will be canceled, with routes between the United Kingdom and Switzerland—such as those from Heathrow, London City, Manchester, and Edinburgh—accounting for up to 12% of the total cancellations. According to AirAdvisor, up to 50,000 UK passengers alone could be affected, with even more disruption expected across Europe and North America.

Why Are These Flights Being Cancelled?

The reasons behind the SWISS cancellations are multi-layered and reflect broader challenges in the aviation industry:

• Pilot Shortage: SWISS is facing a shortage of available pilots, partly due to a new collective labor agreement that reduces working hours and increases the need for more pilots.
• Fleet Issues: Several Airbus A220 aircraft are grounded because of ongoing problems with Pratt & Whitney engines, reducing the number of planes available for service.
• Training Bottlenecks: The introduction of the new Airbus A350 fleet requires extensive retraining for pilots, further limiting the pool of qualified crew.
• High Levels of Leave: Increased parental and sick leave among pilots has added to the staffing crunch.
• Limited External Support: The parent company, Lufthansa Group, and other partner airlines are unable to provide extra crew, as they are also dealing with their own shortages.

Chief Operating Officer Oliver Buchhofer explained, “We regret that we are unable to offer the affected connections as originally planned. In such cases, we inform the affected customers as early as possible. Schedule adjustments are made as far in advance as possible to minimise inconvenience and to find the best possible alternative travel solutions for our passengers.”

Who Is Affected and How?

The cancellations will impact a wide range of travelers, from business passengers on the Zurich–Chicago route to holidaymakers flying between the UK and Switzerland. The disruption is especially significant for those who have already booked flights for the summer period, as they now face uncertainty about their travel plans.

Key groups affected include:

• UK Passengers: Up to 50,000 travelers from the UK may need to rebook or seek refunds.
• European and North American Travelers: Many connecting flights and long-haul journeys, such as Zurich–Chicago, will be less frequent, making travel planning more difficult.
• Business Travelers: Reduced flight options may complicate business trips, especially on popular intercontinental routes.
• Families and Tourists: The summer season is a peak time for vacations, so families and tourists are likely to feel the impact of fewer available seats and higher prices.

What Should Affected Passengers Do?

SWISS has outlined a clear process for passengers whose flights have been canceled:

1. Notification: SWISS is contacting affected passengers directly by email or phone to inform them of the changes.
2. Rebooking: Passengers can accept a new, rerouted itinerary offered by SWISS or request a full refund.
3. Compensation: Under EU261 regulations, travelers may be entitled to additional compensation, depending on the circumstances and how much notice they receive.
4. Customer Support: Passengers are encouraged to contact SWISS customer service or visit the official SWISS website for assistance with rebooking or refunds.

The Zurich–Chicago Route: A Closer Look

One of the most high-profile routes affected by the cancellations is Zurich–Chicago. This service is a key link between Switzerland and the United States 🇺🇸, used by both business and leisure travelers. The frequency of this route will be halved in September and October 2025, meaning fewer options for those needing to travel between these two major cities.

With fewer flights available, passengers may face:

• Longer layovers or indirect routes
• Higher ticket prices due to increased demand on remaining flights
• Limited flexibility for rescheduling or last-minute bookings

Competitor airlines such as British Airways and easyJet are also seeing increased demand, which may further drive up prices and reduce availability.

Why Is There a Pilot Shortage at SWISS?

The pilot shortage at SWISS is the result of several overlapping factors:

• New Labor Agreement: SWISS pilots recently approved a new collective labor agreement that improves working conditions but reduces the number of hours each pilot can fly. This means the airline needs more pilots to operate the same number of flights.
• Training for New Aircraft: The arrival of the Airbus A350 requires pilots to undergo special training, temporarily taking them out of the regular flying schedule.
• High Leave Rates: Many pilots are on parental or sick leave, reducing the available workforce.
• Fleet Groundings: Technical issues with the Airbus A220’s Pratt & Whitney engines have forced several planes out of service, further complicating scheduling.

SWISS is trying to address the shortage by:

• Increasing pilot recruitment targets from 80 to 110 new pilots per year
• Asking older pilots to delay retirement
• Encouraging part-time staff to increase their hours
• Offering a voluntary vacation buyback scheme to boost pilot availability

Despite these efforts, it remains uncertain whether these measures will be enough to resolve the shortage in time for the summer season.

The Broader Impact: What This Means for the Airline Industry

The SWISS cancellations are not happening in isolation. Airlines across Europe are facing similar challenges, with strikes, labor shortages, and technical problems causing widespread disruption. According to analysis by VisaVerge.com, the situation at SWISS is part of a larger trend affecting the entire aviation sector.

Key industry-wide challenges include:

• Labor Shortages: Many airlines are struggling to hire enough pilots, cabin crew, and ground staff as travel demand rebounds after the pandemic.
• Fleet Modernization: The introduction of new aircraft types often requires retraining, which can temporarily reduce the number of available crew.
• Operational Strain: High demand during the summer season puts extra pressure on airlines, making it harder to recover from disruptions.

As a result, passengers across Europe and North America should be prepared for possible delays, cancellations, and higher fares during the peak travel months.

Passenger Rights: What You Need to Know

Under EU261 regulations, passengers whose flights are canceled are entitled to certain protections:

• Full Refund: If your flight is canceled, you can request a full refund of your ticket price.
• Free Rerouting: The airline must offer you an alternative flight to your destination at no extra cost.
• Compensation: Depending on the circumstances and how much notice you receive, you may be eligible for additional compensation.
• Assistance: Airlines must provide meals, refreshments, and accommodation if you are stranded due to a cancellation.

How Is SWISS Responding to the Crisis?

SWISS has taken several steps to try to minimize the impact of the cancellations:

• Early Notification: The airline is informing passengers as early as possible to give them time to make new arrangements.
• Alternative Solutions: SWISS is working to find the best possible alternative travel options for affected passengers.
• Operational Adjustments: The airline is asking older pilots to postpone retirement, encouraging part-time staff to work more hours, and offering incentives for pilots to give up vacation time.
• Increased Recruitment: SWISS is ramping up its pilot hiring efforts, aiming to bring in up to 110 new pilots per year.

Despite these efforts, the airline acknowledges that some disruption is unavoidable. The parent company, Lufthansa Group, is unable to provide additional crew support, as it is also facing its own operational challenges.

What Should Travelers Do Now?

If you have booked a flight with SWISS for travel between April and October 2025, especially on routes like Zurich–Chicago, here are some practical steps to take:

• Check Your Email and Phone: SWISS will contact you directly if your flight is affected.
• Review Your Options: Decide whether you want to accept a rerouted itinerary or request a refund.
• Know Your Rights: Familiarize yourself with EU261 regulations so you understand what compensation and assistance you are entitled to.
• Contact Customer Service: If you have questions or need help, reach out to SWISS through their official website or customer service hotline.
• Monitor the Situation: The situation is evolving, so keep an eye on updates from SWISS and other airlines.

The Future: Will Things Improve?

Looking ahead, SWISS is taking steps to prevent similar disruptions in future seasons. The airline is reviewing its planning processes, expanding pilot training capacity, and working to modernize its fleet. However, with ongoing labor shortages and the possibility of further strikes across the European aviation sector, travelers should be prepared for continued challenges.

Key points for the future:

• Pilot Recruitment: SWISS aims to hire up to 110 new pilots per year, but it may take time for these efforts to have a noticeable impact.
• Operational Planning: The airline is re-evaluating its scheduling and staffing models to better match resources with demand.
• Industry-Wide Issues: Other airlines are facing similar problems, so disruptions may continue across Europe and North America.
