I took it from my home to the Incheon airport. When I take a taxi, it usually costs around KRW 65,000 except the toll. And it definitely goes up for 20% more because it goes via the Seoul outter circular highway. this app stated that it will go up 30% more than usual since it’s far based on their fare policy. I thought and expected around up to KRW 80,000 except the toll even if it costs 10% more. However, it was almost KRW 170,000 except the toll. I was so shocked and suprised. It was almost tripled. Ok. It’s fair and normal based on their fare policy. However, I cannot deny that it’s way more expensive than the black luxurious taxi even. If you go far, just don’t use this app.
