My flight to Lisbon was $200 cheaper if I landed in a different city
I was booking a trip to Portugal and saw a direct flight to Lisbon for $600. But a flight to Porto was only $400, with a 3 hour train ride to Lisbon for about $25. I picked the Porto option, saved over $150, and got to see a cool extra city for an afternoon. Has anyone else saved big by flying into a cheaper nearby airport and taking ground transport?
