Route planning under constraints.
Treat the itinerary as a system with inputs, handovers, buffers and failure modes.
Input: airport and city
The departure and arrival airport determine more than the runway. They shape public-transport access, check-in layout, gate distance, border sequence, baggage reclaim and the time required to reach the actual destination. Compare door-to-door shape rather than only air time.
A secondary airport may be perfectly practical for a flexible leisure journey and awkward for an early meeting. The answer belongs to the traveller’s constraints.
- Name the actual airport
- Include the ground leg
- Check the earliest and latest practical transport connection
Input: date and season
Seasonal demand changes queues, transport resilience, daylight, weather exposure and the number of alternatives when a segment is disrupted. Flexible dates are useful because they reveal different journey shapes, not because this publication can promise a lower price or current availability.
For winter or high-demand travel, plan a larger operational margin and review the airline and airport instructions close to departure.
Output: a plan with recovery
A resilient itinerary answers the recovery question: if the first train is cancelled, if the bag must be checked, if border control is slower or if the terminal changes, what is the next action? A protected connection may transfer some responsibility to the airline; a self-transfer leaves more of the recovery with the passenger.
The plan should be specific enough to use under stress without pretending that the day can be controlled.
Official resources belong to the final decision.
