Trying to complete your SWISS check in but the website or app will not let you continue? A SWISS online check in problem can be stressful, especially when your departure is approaching and you still need your SWISS boarding pass.
An unsuccessful online check-in does not automatically mean that your ticket is invalid or that your flight has been cancelled. There are several legitimate reasons why SWISS may not allow you to complete the process online. The timing of check-in, your booking details, travel documents, operating airline, airport procedures, or a temporary technical problem can all play a role.
If SWISS online check in is not working, start with the following possibilities:
Online check-in has not opened yet.
The online check-in deadline has passed.
Your booking information does not match the reservation.
Additional passport or passenger information is required.
Another airline operates your flight.
Your itinerary includes a codeshare segment with different check-in rules.
Automated check-in is unavailable for your route.
Your booking has recently changed.
The website or SWISS app is experiencing a temporary technical problem.
You need to complete check-in at the airport because of your travel circumstances.
SWISS states that web and mobile check-in are generally available from 23 hours until 1 hour before departure, while exact airport check-in deadlines vary by destination.
One of the easiest explanations for SWISS check in unavailable is that you are checking in too early.
SWISS currently states that online check-in opens 23 hours before departure. Its FAQ also confirms that web and mobile check-in are available from 23 hours to 1 hour before departure.
For example, if your flight leaves tomorrow afternoon but you are trying to check in more than 23 hours beforehand, the check-in option may not be active yet.
Check your scheduled departure time and calculate when the 23-hour window begins.
If you are too early, there may be nothing wrong with your booking. Wait until online check-in opens and try again.
If you are already within the check-in period, move on to the other troubleshooting steps below.
SWISS online and mobile check-in generally closes 1 hour before departure. Airport deadlines can be different and depend on the airport and destination.
This creates an important distinction between online check-in and airport check-in.
If you are already less than an hour from departure and online check-in has closed, repeatedly refreshing the website will not solve the problem. Your priority should be getting to the airport and using the available check-in facilities, assuming you can still meet the airport's deadline.
SWISS recommends arriving around 2 hours before departure for short-haul flights and 3 hours before departure for long-haul flights.
SWISS says passengers can identify themselves for online check-in using their name and SWISS booking code, or through their online profile.
A simple entry error can therefore cause a SWISS check in issue.
Check that:
Your first and last names match the booking.
You are using the correct SWISS booking code.
You have not accidentally used a reference from a separate travel booking.
You are checking the correct flight date.
You are using the latest reservation details if the itinerary has changed.
If you booked through a travel agency or another travel provider, make sure you are using the SWISS reservation reference required for check-in rather than another agency reference.
A particularly common source of confusion is the difference between the airline selling or marketing a flight and the airline actually operating it.
Your itinerary can contain a SWISS flight number while the aircraft is operated by a partner airline.
For codeshare flights, SWISS states that check-in times are determined by the operating airline.
Open your itinerary and look for the operating carrier.
If another airline operates the relevant flight, that carrier may handle the check-in and boarding pass for that segment.
This is especially important on connecting itineraries where different portions of the trip may be operated by different airlines.
Some destinations require airlines to collect additional passenger information before travel.
SWISS says passengers may need to provide additional passport information during online check-in, depending on the destination.
The airline also provides an Advance Passenger Information System process for destinations where additional passenger information is required.
If SWISS asks for passport or travel information, make sure:
Your passport details are accurate.
Your name corresponds with your booking.
Your passport is valid for the journey.
Any required visa or entry authorization has been arranged.
You have completed all mandatory fields.
If the online process cannot complete the required verification, airport staff can assist with the necessary checks.
A recent itinerary change can sometimes explain why your SWISS online check in is not working.
For example, your flight may have been:
Rescheduled
Rebooked
Changed because of an operational disruption
Re-routed
Replaced with another flight
Changed from a SWISS-operated segment to a partner-operated segment
If you have received a new itinerary, use the latest booking information rather than an older confirmation saved in your email or phone.
Compare the information in your current reservation with your original booking.
Pay particular attention to:
Flight number
Departure date
Departure time
Airport
Operating airline
Connection details
If these details have changed, the check-in process may also have changed.
SWISS offers automated check-in for eligible bookings, but it is separate from manually checking in online.
SWISS says automated check-in is available for bookings made through swiss.com and can send the boarding pass automatically by email. It also notes that automated check-in is unavailable for some flight connections.
For certain departures, including flights from Dubrovnik, Niš, Pula, Split, Tirana and Toulon, SWISS states that automated check-in is not available.
That does not necessarily mean that normal online check-in is unavailable.
SWISS advises that if you have not received the boarding pass or notification when expected, you should check your spam folder and then use online check-in or check in at the airport.
A SWISS boarding pass not available message can be different from a failed check-in.
SWISS says mobile boarding passes can be sent by email or text message, printed, or saved in the SWISS app or a digital wallet.
If you cannot print or access your boarding pass, SWISS says you can obtain another one at a check-in machine or check-in desk at the airport, provided you are still within the applicable check-in time.
If you have already checked in:
Check your email inbox and spam folder.
Open your booking again on swiss.com.
Check the SWISS app.
Look for the boarding-pass link sent by email or SMS.
Try downloading or displaying the pass again.
If necessary, get a new boarding pass at the airport.
A missing digital pass does not automatically mean that your ticket has disappeared.
Sometimes SWISS online check in not working is simply a technical problem.
Possible symptoms include:
The check-in page fails to load.
Your booking cannot be retrieved.
The page freezes after you enter your information.
The app displays an error.
Check-in appears to finish but the boarding pass does not load.
Before assuming there is a problem with your reservation, try a few basic technical fixes.
Try:
Opening swiss.com in another browser.
Using a private or incognito browser window.
Switching from Wi-Fi to mobile data or vice versa.
Trying another phone, tablet, or computer.
Updating the SWISS app.
Closing and reopening the app.
Signing out and back into your SWISS account.
Re-entering your booking information manually.
If the problem occurs only on one device or browser, the issue may be technical rather than related to your reservation.
If you want a practical troubleshooting sequence, work through these steps in order.
Make sure you are inside the normal online check-in period of 23 hours to 1 hour before departure.
Enter your name and SWISS booking code carefully.
If your flight is operated by a partner, check that airline's check-in requirements.
Complete any required passport or passenger-information fields.
Use the latest flight information from SWISS.
If the website fails, try the SWISS app. If the app fails, use the website.
SWISS provides check-in desks and self-service check-in options at airports, although availability and opening times vary.
Yes.
SWISS provides airport check-in options at its destinations, including check-in desks and self-service facilities at many airports. The exact options depend on the airport.
If online check-in fails, take your booking information and required travel documents to the airport.
Do not wait until the last possible moment. Airport check-in deadlines vary by destination, and SWISS recommends allowing approximately two hours for short-haul travel and three hours for long-haul travel.
There is no single airport deadline that applies to every SWISS flight.
The closing time depends on factors such as:
Departure airport
Destination
Flight duration
Operating airline
Type of journey
SWISS provides destination-specific check-in times and recommends passengers check the applicable airport information before travelling.
If you arrive after the check-in or baggage-drop deadline, airport staff may not be able to accept you or your baggage even if your flight has not yet departed.
For that reason, treat the published check-in deadline as a hard operational cutoff rather than the time you should aim to arrive.
Having checked baggage does not automatically prevent you from using SWISS online check in.
After completing online check-in, eligible passengers can use baggage-drop facilities where available. SWISS also provides self-service baggage options at a number of airports.
At Zurich Airport, for example, SWISS offers Self Bag Drop facilities, and passengers can prepare their boarding pass and baggage tag before reaching the airport.
If online check-in itself is unavailable, use the airport's normal check-in process.
Travelling with an animal requires additional airport procedures.
SWISS recommends passengers travelling with a pet in the hold go to the check-in desk. It specifically advises bringing the pet to the check-in desk in its appropriate transport container within the recommended time window.
Therefore, if you are travelling with an animal and cannot complete the normal digital process, airport check-in may be the appropriate procedure.
Passengers who need special assistance should allow additional time at the airport.
SWISS states that passengers with special needs, including unaccompanied children and passengers using wheelchairs or with impaired vision or hearing, are handled by airport staff from check-in through boarding.
If your travel arrangements include special assistance, follow the instructions provided by SWISS rather than assuming that every step will be completed through ordinary online check-in.
Codeshare flights require particular attention because the airline shown on your ticket may not be the airline operating the aircraft.
SWISS states that check-in times for codeshare flights are set by the operating airlines.
Before departure, identify:
The flight number.
The marketing airline.
The operating airline.
Where that airline requires you to check in.
The applicable check-in deadline.
This can prevent a common SWISS check in issue where a passenger tries to use SWISS's check-in service for a flight actually handled by a partner.
If your SWISS check in problem today occurs several hours before departure, you still have time to troubleshoot the online process.
But if your flight is approaching the airport check-in deadline, stop spending time repeatedly refreshing the website.
Take your:
Passport or required ID
Booking confirmation
Latest itinerary
Visa or entry documents, if applicable
Any relevant travel documentation
and go to the airport.
SWISS provides check-in desks and self-service options, with availability depending on the airport.
A few simple steps can reduce the chance of a last-minute problem.
For standard SWISS online check-in, the window opens 23 hours before departure.
Save your latest booking confirmation somewhere accessible on your phone.
This is especially important when your itinerary contains codeshare or partner-operated flights.
Complete any additional passenger or passport information required for your destination.
Save the boarding pass in the SWISS app, your digital wallet, or another secure location after receiving it.
If online check-in fails, you should still have enough time to use a kiosk or staffed check-in desk.
The most common explanations are that online check-in has not opened, the online deadline has passed, booking information is incorrect, additional passenger information is required, or another airline operates the flight. Technical problems can also prevent online check-in.
SWISS currently states that online check-in opens 23 hours before departure and is generally available until 1 hour before departure.
Check whether you are outside the online check-in window, whether your itinerary contains a partner-operated flight, or whether your booking requires additional travel-document information.
First check your booking reference, name, flight timing, operating airline, and travel-document requirements. Then try the SWISS app or another browser/device. If the problem continues, use airport check-in.
Your boarding pass may not have been delivered or displayed correctly even though other parts of the check-in process are complete. SWISS says boarding passes can be delivered by email or SMS, printed, or stored in the SWISS app or a digital wallet.
Yes. SWISS says passengers who cannot print or access their boarding pass can obtain one from a check-in machine or check-in desk at the airport, provided they are within the applicable check-in time.
Yes. SWISS provides airport check-in desks and self-service check-in options at many airports. Availability and opening times vary by location.
The process can differ for codeshare flights because the operating airline determines the applicable check-in times and procedures. Check which airline actually operates your flight before attempting check-in.
Check your spam folder first. SWISS says that if the automated boarding pass or notification has not arrived when expected, you should use online check-in or check in at the airport instead.
Online check-in can be used with baggage on eligible journeys. Afterward, you can use the relevant baggage-drop facility where available. SWISS offers self-service baggage options at a number of airports.
Do not spend too long troubleshooting online. If you are still within the airport check-in deadline, go directly to the appropriate SWISS check-in facility with your booking details and travel documents.
A SWISS check in problem does not necessarily indicate a problem with your ticket. In many cases, the reason is straightforward: the online check-in window has not opened, it has already closed, the booking information is incorrect, or additional passenger information is required.
If everything looks correct, check whether another airline operates your flight. Codeshare flights can have different check-in procedures and deadlines, making the operating airline an important detail to verify.
If SWISS online check in is not working, try the SWISS app, another browser, or another device. If your SWISS boarding pass is not available, check your email and app before assuming the check-in failed.
Most importantly, do not let a website problem cause you to miss an airport deadline. SWISS provides airport check-in desks and self-service facilities at many locations, so airport check-in is the practical fallback when online check-in cannot be completed.
