You have selected a Business upgrade offer that is based on an Economy fare. Rebookings or refunds are thus governed by the same terms and conditions as the underlying Economy fare. If the upgrade booking class is unavailable, any price difference between the underlying Economy fare and the upgrade offer cannot be refunded. These offers are not valid on codeshare flights. If a flight is missed due to a delayed connnecting flight or if a flight is cancelled, SWISS can rebook the passenger in Business Class on the next SWISS flight if a seat is available. If the rebooking is on a flight operated by another airline, only onward transport in Economy Class is guaranteed, in which case the amount of the SWISS Business Upgrade would be refunded.
