Mulhouse sits just beyond Basel in the Alsace, and the practical question on this route is always the same: whether the passenger should have flown into the EuroAirport instead. It is a genuinely trinational airport with a French sector, and for a Mulhouse destination it is usually the better arrival.
When Zurich is the arrival anyway — a long-haul that only lands here, a connection that could not be changed — the run is straightforward motorway with one border on it.
