Cheap for what it is, priced annually rather than monthly, and the human-expert fallback covers the cases where a generated itinerary would otherwise fall apart. It is still a recommendation layer on top of booking partners, so verify prices and availability before committing.
Pros
- Annual pricing at $49 rather than a monthly subscription
- Free tier covers core planning
- Human travel experts available for complex bookings
- Named operating company with a Berlin address
Cons
- No public API
- Fares and availability come from partners and need checking
- No mobile app documented on the site
