Not a great experience. We were on an Air France flight from the US that was delayed. We missed our connecting flight because of the delay, but AF did nothing to help us. We ended up having to book an $800 rental car and drive 6 hours to our destination in Amsterdam, because flights and trains were full.

Getting around Porto

Buses, trams and the metro will get you around the city quickly, and the funiculars can take you from the Ribeira to the city’s centre. Local trains can take you to the outer edges of the city and to the beaches. Avoid travelling during rush hour, as public transport can get very crowded. Look for discount or multiple-trip tickets such as the Passe Turistico, bulhete diario (day pass) and the rechargeable Andante Card to save money.
