Actually there is a ‘bug’: This particular combination of provided cableway timetable data without available respective online tickets is not reflected on the displayed ticket information before you buy it. If a regular ticket would be purchased for 65/130.-, then the applicable route Zurich - Zermatt (NOT till Klein Matterhorn) would be mentioned only on the issued point-to-point ticket after purchasing it.
Same situation with some other cable cars, e.g. Hoher Kasten.
Bu there are also additional bugs in the timetable data provided by the Zermatt cableways in this case: Apart from the fact that there’s a gondola about every minute (so stated departure times only make limited sense), there’s no transfer at Furi nor at Schwarzsee, you simply remain seated in the same gondola until Trockener Steg.
However the cableway timetable data do help estimating the overall travel times, which is probably the reason why they are provided to SBB at all.
