Converting route-level demand, utilisation, economics, reliability and strategic network fit into decision-ready service recommendations across 20 European corridors.
Route planning cannot rely on passenger volume alone. Strong demand can still hide weak margins, poor reliability or a network role that requires a different action. This project builds a structured way to see the full picture before committing capacity, so decisions are based on sustainable performance, not assumptions.
High load factors do not guarantee healthy contribution or positive commercial outcomes.
On-time performance and cancellations can erode customer trust and revenue quality.
Some routes strengthen the network even if their stand-alone margin is modest.
Inconsistent or diluted data can mislead decisions and waste capacity.
Corridors are not isolated. The project first understands each route in the context of the wider European network. Mapping passenger volume and recommended network action highlights where to expand, optimise, maintain or review - where it creates the most value.

A weighted prioritisation model evaluates each route across five dimensions to identify the strongest candidates for expansion and the routes that need optimisation.
| Corridor | Demand | Margin | Reliability | Network fit | Score | Recommended action |
|---|---|---|---|---|---|---|
| Berlin–Munich | High | Strong | High | High | 4.2 | |
| Munich–Vienna | High | Strong | High | Medium | 3.9 | |
| Berlin–Prague | Medium | Medium | Medium | High | 3.1 | Optimise |
| Cologne–Amsterdam | Medium | Medium | High | Medium | 3.0 | Optimise |
| Berlin–Warsaw | High | Medium | Low | Medium | 2.8 | Maintain |
| Berlin–Copenhagen | Low | Weak | Low | Medium | 2.1 | Review |
| Leipzig–Dresden | Low | Weak | Low | Low | 1.8 | Review |

The revised schedule removes weak late-night departures and shifts capacity toward stronger morning, afternoon and weekend demand windows - testing whether better timing can improve utilisation before the network adds more total trips.

Berlin–Munich is used as a sample corridor test - the same model can be extended through to whether additional service justifies added capacity.
The corridor combines high demand, resilient service quality and strategic fit. The proposal recommends adding two peak departures during Friday and Sunday demand windows. Decision logic: expand only when the pilot confirms load factor and margin thresholds are met.

Recommendation
Run a four-week pilot with two additional peak departures. Make the change permanent only when incremental load factor stays at or above 75% and weekly contribution reaches at least €250k.
≈ €85k incremental weekly contribution · fewer >90% load events on peak days · stronger connections into Hamburg and Cologne.
Vehicle and crew availability, competitive discounting, congestion during peak windows.
A robust data foundation turns raw operational inputs into visibility and monitoring, enabling exception management and faster, clearer decisions. Each route-week record connects demand, economics, reliability and network context in one structured table.
Decisions are tested and phased. Pilots are designed to validate customer value and only scale what works.
| Test / action | Corridor | Business question | Gate | Status |
|---|---|---|---|---|
| Four-week peak departure test | Berlin–Munich | Does added capacity sustain margin? | Load factor ≥75%, contribution ≥€250k/week | Piloted |
| Two early-morning departures | Munich–Vienna | Does earlier timing lift utilisation without hurting reliability? | On-time performance holds, load factor improves | In progress |
| Off-peak fare adjustment | Leipzig–Dresden, Berlin–Copenhagen | Can pricing repair weak off-peak utilisation? | Contribution margin improves, no volume loss | Not started |
Small, time-boxed tests reduce risk before real demand is committed.
Reliability and on-time performance are non-negotiable.
Margin and contribution must improve with the change.
Expand what works, redesign or exit what doesn't.
From raw data to a decision-ready recommendation.
A transparent, repeatable model across five dimensions.
Demand, margin and cost translated into one commercial case.
Measurable gates before any capacity becomes permanent.
One weighted model. Clearer priorities. Stronger network decisions.
This project is an independent recruitment case study built using a simulated and anonymised route-week dataset. It was not commissioned by, conducted inside or endorsed by Flix. It shows how route data can be transformed into repeatable, evidence-based decisions across expansion, optimisation, maintenance and review.
