With the Economy Flex fare you will enjoy even more advantages with SWISS on Europe flights. This fare provides maximum flexibility and is perfect when your travel plans change suddenly and you need to change your booking. When boarding, be among the first on the plane thanks to Priority Boarding. Watch out for the black «Priority Boarding» symbol on mobile and self-printed boarding passes. If you obtain your boarding pass at a self-service check-in machine or at the traditional counter, the Eco-Flex printout entitles you to priority boarding. SWISS is thereby aligning itself with Lufthansa and Austrian Airlines for whom priority boarding has been a standard component of the Economy Flex fare for some time already.
