The changes processed on swiss.com are limited to the flight booking only. No changes to any other service included in your package (e.g. hotel, rental car etc.) will be processed. It is in the sole responsibility of the person processing the flight change on swiss.com to make sure that the other services, which are part of a package purchased with a Travel Agency, are changed as well. We don’t recommend to process changes to flights, which are part of service packages purchased with a Travel Agency, online but ask you to contact your Travel Agency instead. SWISS shall not be liable for damages resulting from flight changes processed on swiss.com which result in the desynchronization of services included in Travel Agency service packages.
