Edelweiss Air, Switzerland...long haul ops with their A330.
Only one single aircraft, if it goes tech another is leased in.
Destinations are only the Canaries short / mid haul and the Maledives, Brazil, the Caribbean and Japan (seasonal) long haul.
Most destinations served once or twice a week only, gives the crews a lovely long layover at destination
apart from Punta Cana I believe, which is min. rest.
