Our duration estimates include time for transfers, and are generally conservative. For example, our estimate for Hanover, Germany to Bourges, France is approximately 11 hours by train. This estimate includes around 2.5 hours for the four transfers, and around 8.5 hours for actual travel time.
For international flights, approximately 2 hours is included for airport related activities, such as check-in, security, and immigration. If you’re worried about having enough time to make transfers, we strongly recommend visiting the relevant transport company websites to check schedules and get more specific advice.
