Airlines can schedule multiple flights with the same flight number on the same day (sometimes on the same route and sometimes on different flight segments). This varies by carrier. Something less common but what is confusing and does occur is two flights with the same flight number on the same route in the air at the same time. This is most common with flights in Asia and for some smaller North American regional carriers.
