Swiss and Lufthansa are expanding their codeshare agreement to cover six new routes within Europe.
Swiss has already added Lufthansa's LX flight code to its services from Munich to Naples and Sofia.
On May 1, it will add the LX code to its flights from Frankfurt to Bilbao, and on its services from Munich to Bilbao, Krakow and Toulouse, reports airlineroute.net.
Two years ago, the airlines launched a free chauffeur-driven car service to and from selected UK airports for their first class passengers (see news, May 2013).
Swiss added 22 new destinations from its Zurich hub at the start of this summer season in late March (see news, March 23).
