SWISS has launched their Spring Business Fare Sale to Europe with fares starting in the $2500 range. The best prices can be found from US Eastern gateways such as Boston, New York, and Washington. As you move into the midwest, fares from Chicago start in the $2800 range and from the west coast, it will only take $3100 to get to Europe.
The lowest fares are to destinations in Switzerland, Spain, or Italy, but the sale does apply to all of SWISS’ European destinations.
The fare calendar suggests that all travel needs to take place with April. For some reason the link to the fare terms and conditions that SWISS has provided on their site reflect a fare sale from December.
