There are a several Swiss credit cards, but they are not available in the U.S., deal with it. Swiss shares the Miles&More frequent flyer program with Lufthansa and several other airlines, so you may get a Miles&More card. Beware of high annual fee and limited earnings, though. Better still, get a travel credit card and never bother with a question of whether there is a card for your favorite airline. The miles earned are applicable for any of them! And the level of earnings is the same as on any co-branded card, sometimes more. For example, the Discover it® Miles card offers you 1.5 miles on all purchases. Seeing that you don’t spend more than 50% on your travels, it beats most of the card on the market.
