Getting around Europe is easy once you know which websites to use to find the best or least expensive options. You can get around by flight, bus, train, or shared car services. There are two sites I use, Rome2rio and Google Flights.
Rome2rio provides different ways to get from one city to another. It shows you approximate costs as well as how long the trip will last.
Flights within Europe are relatively inexpensive. Google Flights is a flight search engine that helps you find the best deals available. Keep in mind European airlines tend to charge you extra for seat selection, food/snacks, and to carry on or check in luggage. Check the airline’s website for more information.
