How to Compare Flights, Trains and Buses in One Search

A practical guide to using Solvoya to find the cheapest way between two cities, whether that turns out to be a plane, a train or a bus.

Most people plan a trip with five browser tabs open: one for flights, one for trains, one for buses, and a couple more for the operators the first three missed. It is slow, and it quietly hides the best option. A €19 flight can end up costing €70 after bags and airport transfers, while a direct train you never checked was cheaper and dropped you in the city centre. This guide shows how to compare every mode in a single search so the real cheapest route is the one you actually see.

Why one search beats five tabs

The problem with searching each transport type separately is that you never compare them on equal terms. Flight aggregators show flights, rail sites show trains, and bus operators show buses, so you end up guessing which mode wins on your route. For short hops under 500 km, a train or bus is often cheaper and faster door-to-door than flying, once you count the trip to a far-flung airport and the wait at security. On longer legs, a budget flight usually wins. The only way to know is to put all three side by side.

Solvoya does exactly that: you enter your origin and destination once, and it queries flights, trains and buses at the same time, then ranks everything by price. Ryanair, Google Flights, national railways like CP, Renfe and Deutsche Bahn, plus coach operators like FlixBus and Gipsyy all appear in the same list.

Running your first search

Start on the home page and fill in three things: where you are leaving from, where you want to go, and your dates. The origin and destination fields autocomplete as you type, so "Porto" or "Madrid" is enough. A few tips to get better results:

Use city names, not just airports. Typing a city pulls in nearby airports, train stations and bus stops, not only the main airport. That matters when a smaller station has the cheaper connection.
Try one-way first. If your dates are flexible, run a one-way search to see the baseline price, then add a return date to compare round-trip fares.
Be honest about flexibility. Shifting your departure by a day or two often changes the price more than any other single factor.

Solvoya searches all matching operators in parallel and streams the results in as they arrive, so you do not wait for the slowest one to finish before seeing the cheapest.

Reading the results properly

Once results load, a few details are worth understanding so you compare like for like:

Total price, not headline price. For round trips, Solvoya ranks by the real combined cost of the outbound and return legs, not two separate one-way teasers added together. This avoids the classic trap of a fare that looks half the price it really is.
Mode is always visible. Each result is tagged as a flight, train or bus with the operator's logo, so you can weigh a slightly pricier train that lands you downtown against a cheaper flight to an airport an hour away.
Self-transfer options. On some routes Solvoya finds a cheaper journey by combining two separate tickets through a hub, the kind of virtual connection the big airlines never show you. These are flagged clearly so you know it is two bookings, not one protected ticket.

Filter and sort until the list matches what you care about, whether that is the absolute lowest price, the fastest journey, or the fewest changes.

Discovering where to go with the Explorer

Sometimes you know you want to travel but not where. The Explorer flips the search around: instead of naming a destination, you give an origin and let it surface the cheapest places you can reach right now. It is the fastest way to turn a free weekend and a small budget into an actual trip, and it covers flights, trains and buses just like the main search, so a cheap overnight coach can beat a flight you would never have thought to look for.

Paying with points and miles

If you collect frequent-flyer currency, the Points search checks award availability so you can spend miles instead of cash. Solvoya supports Iberia Avios with a calendar view of how many Avios each day costs, and Smiles for routes across the Smiles network. It is a quick way to see whether a route is a good use of your balance before you commit them.

Putting it together

The habit worth building is simple: before you book anything, run the route through a single search that includes every mode. On a short intercity hop you may find the train wins on both price and convenience; on a longer trip a budget flight or a self-transfer combination might be far cheaper than the direct option the airline pushes. Either way, you decide with the full picture in front of you instead of guessing across five tabs. That is the whole point of searching flights, trains and buses together.
