What This Site Is For

TravelTime Planner is designed for people who want a practical answer to "when should I leave?" without building a spreadsheet every time they travel. The site covers general flight and rail departure planning, including how to think about buffers, route risk, and pre-departure preparation.

The calculator is meant to support planning, not to replace operator instructions. Airline, airport, rail operator, and station guidance still take priority over any general baseline published here.

Editorial Approach

Content on this site is written and reviewed by the TravelTime Planner Editorial Team. Pages are updated when the planning framework changes, when the site structure changes, or when source links used for general guidance need review.

We aim to keep content narrow in scope, practical in tone, and clear about uncertainty. Where the correct answer depends on a specific operator or location, we recommend checking the operator directly instead of pretending one generic rule applies everywhere.
