Anyone approaching you inside the terminal is off-rank — Cape Town's own guidebook calls these 'pirate' taxis, with quoted prices diverging from anything paid and real safety concerns behind them.
MyCiTi is fully tap-in/tap-out: the A01 needs a R90 single-trip card from the station kiosk (or a loaded myconnect). There is no driver to pay and no cash fallback at the bus stop.
When the Emirates or KLM widebody clears, hundreds hit the same e-hailing queue at once — the usual R150–250 City Bowl fare jumps to R350+, and the 05:00–21:30 window hides it from early/late travelers in the other direction.
Some rank drivers skip the meter and state a flat 'airport fare' — 2026 guides record R500+ quotes to the City Bowl for a 20 km trip the app does at R200.
