BlaBcar vs TGV vs FlixBus

A multi-modal cost / time / CO₂ comparator for any French intercity route. Plus a unique signal: at what booking window does the TGV stop being cheaper than BlaBcar?

What this tool actually solves

TGV wins on speed but the price varies 4× depending on how early you book. BlaBcar is cheaper but you have less control over timing, less luggage space and the driver's choice of departure city matters. FlixBus is the slow-and-cheap option but the carbon footprint is acceptable if the bus is half full. This tool ranks them on cost, time and CO₂.

How to read the result

Each row is one mode, with the door-to-door time (including city-to-station and station-to-city transfers), price for the chosen number of passengers and booking window, and the CO₂ estimate. The "winning option" cell summarises when each wins.

Limitations

BlaBcar prices vary by driver, vehicle and demand — published averages are ±25%. TGV INOUI fares follow dynamic pricing — what we show is the median for the chosen window, not a quote. FlixBus prices are stable but route frequency is seasonal (most daily in summer, less in winter).

FAQ

Is BlaBcar safe?
Yes, with normal precautions: read the driver's profile (verified blue badge), don't sit in the front seat on first rides, meet in a public place for pickup. BlaBcar carries a third-party liability insurance up to €1M for all passengers, including medical coverage. Cancellation refunds depend on the driver — most offer a 50% refund if cancelled 24h+ ahead.
How early do I need to book a cheap TGV?
The cheapest TGV INOUI tickets drop 4 months before departure, between the 3rd and 4th week. OUIGO tickets drop 6 months ahead but with smaller initial inventory. The first week after a schedule opens is usually cheapest; the last week is the most expensive, often 2×–4× the cheapest fare.
