Omio (originally GoEuro) is a travel search and booking platform aimed at making intercity travel easier to plan across trains, buses and flights. The site aggregates schedules, fares and trip durations from national rail operators, low-cost airlines and long-distance bus carriers so you can compare multiple modes in one search. The interface emphasizes route duration and transfer details, which helps when comparing a direct but more expensive option with a slower, cheaper connection.

The platform covers a wide range of European routes and also lists services that connect Europe with nearby regions; availability varies by carrier. Omio’s app and website let you filter by duration, number of changes and carrier, and in many cases you can buy a ticket directly through Omio and receive an e-ticket. For some operators the booking completes on the carrier’s site, so ticket delivery method and support are provided by that partner.

Practically, Omio is strongest when you need a quick comparison between trains, buses and flights for the same route and want a single interface instead of visiting multiple carrier sites. It’s helpful for planning multi-leg trips since the search results show transfer times and platform or station names when available. Customer service and refund policies are handled on a per-booking basis: Omio can assist with issues for bookings made through its platform, but many policies (cancellations, changes, seat reservations) depend on the original carrier and fare type. The app is useful for storing mobile tickets where supported, and the site displays booking conditions clearly before checkout so you can see whether a ticket is changeable or refundable.
