For airport transfers, city buses 55 and 65 run from the airport to the centre of town, with bus 65 connecting to Łódź Kaliska train station. Otherwise, a taxi to the centre will cost about 40zł.
Łódź's public transport system includes trams and buses, both of which use the same ticket system. A ticket becomes valid for a set length of time after you validate it in the machine on board, and remains valid for unlimited transfers between bus and tramlines. Tickets valid for 40/60 minutes cost 2.60/3.40zł; a 24-hour ticket costs 12zł.
