You have a confirmed ticket and you checked-in for your flight on time, but you were still denied boarding by SWISS. The reason? Your flight was overbooked. So, what happens now? 

If you were involuntarily denied boarding a SWISS flight because of overbooking, you’re entitled to as much as £520 (€600) in compensation.

So, in this guide, you’ll learn your rights and what to expect in these situations as well as some helpful tips to avoid denied boarding in the future.

What SWISS Owes You for Denied Boarding 

Anytime you fly with SWISS in the EU or UK, you are protected by EU Regulation EU261 and the UK’s UK261. Both regulations state that if you are involuntarily denied boarding because of overbooking, SWISS must provide you with the following:

• A replacement flight to your destination at no additional cost
• A refund if you don’t want to continue with your journey
• Meals, refreshments, and access to 2 free phone calls, emails or wi-fi at the airport if you have to wait for your new flight to depart. 
• Hotel accommodation and transport there and back to the airport if you must wait overnight for your new flight to depart.

SWISS Compensation for Overbooked Flights

If your flight was oversold and you were involuntarily denied boarding, you may be eligible for compensation for denied boarding between £220 (€250) and £520 (€600), depending on the flight distance (see the table below).

However, your compensation from SWISS could be halved if you accept a rebooking and arrive within 2 hours of your original flight, for flights up to 1,500 km, within 3 hours for flights between 1,500- 3,500 km or within 4 hours for flights longer than 3,500 km.

What to Do if You’re Denied Boarding by SWISS

1. Get written confirmation of why you were denied boarding. Ask SWISS gate agents for a document describing why you were involuntarily denied boarding. This should include the amount of compensation you’re owed.
2. Request a replacement flight. Also, you might want to ask about a seat upgrade on your new flight or lounge access if you have to wait. If the denied boarding incident made your travel plans useless, you can also request a full ticket refund and a return flight to your original departure point.
3. Ask for care and assistance if you are forced to wait for hours at the airport for your flight, SWISS will most likely provide coupons or vouchers.
4. Start collecting evidence. Collect as much supporting documentation as possible, including communication with SWISS agents, any documents you were given, and any other information. If, for some reason, you don’t get the compensation you’re owed, you can use this to file a claim.

Why SWISS Overbooks Their Flights

With all the sophisticated tools available these days, you might be wondering why SWISS overbooks flights and why they don’t do more to prevent denied boarding.

Basically, SWISS wants to make sure that each flight is booked to capacity to maximise profits. So, to do this, they employ software programs and many other tools to carefully calculate how many passengers are likely to miss a particular flight. Some passengers don’t make it to the airport in time, others cancel, and another group will miss their flight because of earlier flight cancellations or delays 

This system works well most of the time as the estimations are fairly accurate, but when all travellers show up to board a flight that has been oversold, then SWISS has to work fast to get some of the passengers to take a different flight instead.

What Happens when a SWISS Flight is Overbooked

When SWISS overbooks a flight and all ticketed passengers arrive at the gate to board, they will first ask for volunteers to surrender their seat in exchange for an agreed-upon compensation package. These deals are designed to make it enticing for passengers, so if you have the ability to take a later flight, it might be worth it.

As the flight gets closer to its departure time, SWISS will begin choosing passengers to involuntarily deny boarding if they don’t get enough willing volunteers. Usually, passengers who have checked-in for their flight last will be chosen first along with those seated in the least expensive seats. However, anyone with disabilities, minors travelling alone, and families with small children will not be selected for denied boarding.

When You Won’t be Compensated for Denied Boarding

Not every denied boarding situation will be eligible for compensation. The following list provides a few circumstances when SWISS will not compensate you for denied boarding.

• Intoxication or acting under the influence of illegal drugs
• Interfering with the duties of the flight crew
• Failure to have the correct travel documents
• Posing a security or safety concern
• Engaging in unruly behaviour towards the crew and other passengers. An example is physically assaulting a passenger or threatening airline staff.
• Presenting communicable health issues 

Frequently Overbooked SWISS Routes

As a general rule, the most frequently overbooked flights are those with the busiest routes. Also, you might find that overbooking happens more during peak travel and holiday seasons. To help you avoid a denied boarding experience, try to steer clear of the following routes or try to avoid them during busy travel times.

• Zurich (ZRH) to London Heathrow (LHR)
• Zurich (ZRH) to Berlin Brandenburg (BER)
• Zurich (ZRH) to Amsterdam Schiphol (AMS)
• Zurich (ZRH) to Palma de Mallorca (PMI)
