Omio review

Omio is the broadest app on this list. Its App Store listing says it compares more than 3,000 transport companies across 45+ countries, and the train partners it names span three continents: Amtrak and VIA Rail in North America, Eurostar, SNCF, Deutsche Bahn, Trenitalia, Renfe, Italo, Iryo and SBB in Europe, and Shinkansen routes plus the Japan Rail Pass in Japan. Buses, flights and ferries sit in the same search, so a trip like Milan to Rome by train and then a ferry to an island can be planned in one place. Mobile tickets live in the app, and live updates cover platform changes and delays where the operator provides them. A booking also includes 2 days of free eSIM data, up to 1GB, through Kolet. The main catch is cost transparency: Omio's help center says its service fee depends on the trip, the platform and the booking and travel dates, and that many bookings have none, so compare the checkout total with the operator's own site.
