Are you travelling with hand baggage only and want to save time at the airport? Then opt for automated check-in. You can benefit from this option if you sign up via "Manage booking" at swiss.com, no later than 24 hours before departure and automated check-in is offered for your destination. You can book your chosen seat free of charge or for a fee, depending on the route and your flight class, when you make your online booking.
If you subsequently want to edit your registration for automated check-in or your boarding pass option, you can do this with Manage booking.
If you have not received a boarding pass or a notification by 20 hours before your departure, you will not be able to use automated check-in. However, you will be able to choose from all the other check-in options, as usual.
