The General Rule: Which Transport Wins by Distance?

| 500–1000km (Barcelona, Madrid, Frankfurt) | FlixBus or Ryanair | Train or flight (depends) | Flight |
| 1000–2000km (Rome, Lisbon, Athens) | Ryanair/easyJet | Flight | Flight |

FlixBus — The Secret Weapon for Budget European Travel
FlixBus is the most underused budget travel option for UK-to-Europe journeys. Overnight coaches from London to Paris, Amsterdam and Brussels depart from Victoria Coach Station and arrive city-centre. At £22–£35 including a full checked bag, they're significantly cheaper than flights or Eurostar for budget-conscious travellers willing to sacrifice a night's sleep.
- London Victoria to Paris: From £22, departs ~23:00, arrives ~08:30
- London to Amsterdam: From £30, overnight journey
- London to Brussels: From £22, overnight option
- Luggage: 2 large bags included at no extra cost — better than budget airlines
💡 Pro Tip: Search FlixBus routes on Omio alongside trains and flights. The overnight bus comparison is particularly useful — you save a night's accommodation AND transport cost in one journey.
