Candidate airports
A configuration-driven hub list covers major and low-cost European departure points.
Under the hood
How it works
RoatZero builds complete route candidates from provider segments, validates transfer buffers, removes dominated options, and ranks the remaining itineraries by price, time and risk.
Positioning routes
The MVP combines clearly labelled train, coach, rideshare, and airport-transfer estimates with a two-segment limit.
Long-haul fares
Duffel supplies live flight fares when configured. Automated tests use deterministic fixtures and never consume live searches.
Risk scoring
Separate tickets, self-transfer, airport changes, overnight segments and tight buffers influence route risk.
