Airlines price routes independently. Sometimes flying A → Porto → B costs less than A → B direct. The difference is your savings — and Porto is your free city.
TAP and Ryanair make Porto a natural European stopover. São Bento train station was completed in 1916 and its entrance hall is lined with 20,000 azulejo tiles depicting Portuguese history — it is used daily as a commuter station and costs nothing to enter. Porto costs $80/day. The savings are the port wine tour.
