Bus 175 is the ultimate budget hack from Chopin Airport - runs every 15-20 minutes from 5:30am until 11:20pm daily. The ticket machine at the bus stop accepts coins and contactless cards (4.40 PLN for 75 minutes of city transport). Compare that to taxi quotes of 80-120 PLN or Uber at 45-60 PLN to centrum.

Exact route breakdown: Terminal departures → Rondo Waszyngtona → Metro Centrum (perfect for M1/M2 connections) → Aleje Jerozolimskie → Dworzec Centralny (main train station) → continues to Krakowskie Przedmieście for Old Town access. Total journey time 45 minutes vs 25 minutes by taxi, but you save 40+ PLN every single trip.

Download Jakdojade app before you land - shows live bus arrivals and exactly which stop you need. The app works flawlessly and prevents that confused tourist look at bus stops. Pro tip: if you're heading straight to Old Town, stay on until Krakowskie Przedmieście stop instead of transferring at Metro Centrum.
