The new price concept, with one-way tickets from 89 Swiss francs, was reported by the Travel Inside journal and picked up by Swiss media on Thursday.
The 89-franc deal applies to flights from Zurich to a number of EU cities, including Paris, Berlin, Birmingham and Barcelona.
For other destinations – Amsterdam, Florence, Hanover, Prague and Oslo – passengers will have to buy a return ticket.
Business rates will be available from 299 francs.
“The airline is trying to stay competitive with these low price ticket offers,” aviation expert Andreas Wittmer told the 20 Minuten newspaper.
The new campaign starts on July 9th, but tickets at the special rate are already available to purchase online, a spokesperson for the airline told the Swiss news agency SDA.
In September last year the carrier – owned by the German airline Lufthansa – introduced a similar concept from Geneva.
Swiss is under pressure from low-cost carriers in Switzerland, including newcomer Etihad Regional, which is seen as attempting to undercut established airlines with an aggressive pricing strategy.
However, Swiss denied that its campaign was a response to Etihad’s tactics. Myriam Ziesack told SDA it was a reaction to market conditions in general.
