TopApps analysis
BlaBlaCar puts you in a car with someone already making your journey, often for less than the coach and without depending on station timetables.
BlaBlaCar puts drivers with empty seats in touch with travellers heading the same way: you cover intercity routes for a fraction of the train fare by sharing a car, with verified profiles and ratings. It also lists coaches (BlaBlaCar Bus) so you can compare. On routes with poor public transport, it is often the only sensible option.
Pros
- Much cheaper than train or plane
- Verified profiles with ratings
- Reaches places public transport does not
Cons
- You depend on the driver being punctual
- Booking fee on every reservation
- Less flexible if your plans change

Frequently asked questions
What is the cheapest way to travel between European cities?
Usually a coach booked in advance, or car sharing. Alsa and FlixBus charge much lower fares the earlier you buy, and BlaBlaCar tends to land at a similar price or below. It is worth comparing on Omio, because on some routes discounted train tickets drop to coach prices.
How far in advance should I buy a bus ticket?
The earlier the better: both Alsa and FlixBus use dynamic pricing that climbs as the vehicle fills up. Buying two or three weeks ahead usually saves a good deal compared with the same day. Around bank holidays or Christmas, book with even more margin, because seats sell out.
Is travelling with BlaBlaCar safe?
The platform verifies profiles, shows ratings for every driver and passenger, and payment goes through the app rather than in cash. The sensible advice still applies: check the driver's ratings and trip count, make sure the profile is verified, and avoid arranging anything outside the app.
What happens if I miss the bus?
It depends on the fare. The cheapest FlixBus and Alsa tickets allow no changes or refunds, so missing the bus means losing the ticket. Flexible fares, slightly more expensive, let you change the time until shortly before departure. If your schedule is tight, the price gap for a flexible fare is usually worth it.
