TAP Air Portugal and Aer Lingus provide full-service alternatives with more flexibility. The flight takes about 2.5 hours — comfortable for a city break or the start of a longer Portuguese road trip.
Lisbon has become one of Europe's most beloved cities for its pastéis de nata, hilltop trams, Fado music scene, and outstanding seafood. From Lisbon, the Algarve is 2.5 hours south, Évora in the Alentejo wine region is 1.5 hours east, and the fairy-tale palaces of Sintra are 40 minutes west.
