Festpreis (fixed price) is the alternative to the standard taxi tariff (Taxameter) — instead of starting a meter and accumulating cents per minute and metre, we agree a single price up-front. The price is calculated from your origin postcode to Stuttgart Airport (or vice versa), based on a published distance matrix, and is locked the moment you confirm.
For airport transfers the value is predictability: the taximeter keeps running every minute spent in B27 traffic and only settles at the destination — so its total swings with the day. The fixed price removes that variance. You see one number when you book, and you pay exactly that number — no surge, no surprises, whatever the traffic.
The matrix is built once, then recalibrated quarterly against actual fuel, drive-time, and the underlying Stuttgart taxi tariff. We don't play games with surge pricing — every customer who books the same route at the same time of week sees the same price, regardless of how busy our dispatch is.
