Buy the 90-minute PID ticket: CZK 50 on paper or at a machine, CZK 46 in the app, CZK 55 by SMS. It covers transfers across Prague. The 30-minute ticket will not reliably last the whole trip. Children under 15 and anyone 65 or over travel free, visitors included; children from 10 need proof of age.
Luggage. Free up to 25 × 45 × 70 cm; a larger bag needs a luggage ticket (CZK 25, or 23 in the app) with a 30- or 90-minute fare, and travels free with a 24- or 72-hour ticket. The 24-metre trolleybuses have a baggage area; the metro does not.
