Swiss leisure carrier Edelweiss has detailed its plans to launch twice-weekly flights from Zurich to Las Vegas' McCarran International airport in the spring.

Edelweiss will initially operate the new route on Mondays and Fridays from 5 May. The Swiss carrier will deploy refurbished 275-seat Airbus A330 aircraft on the route from June.

"We realised the strong demand for this route from the Swiss market and are more than happy to meet the wish of so many Swiss people who want to travel to the entertainment capital of the world with our new service," says Edelweiss chief executive Karl Kistler.

The route marks the carrier's second US destination and the first connection between Las Vegas and Switzerland.
