In terms of ticketing, what does 'consecutive numbers' signify for issued tickets?

In the context of ticketing, 'consecutive numbers' signifies that the tickets correspond to a single itinerary. This means that the tickets are usually part of a single journey involving multiple segments or legs. Airlines often use consecutive numbering to indicate that the tickets are interconnected and should be treated as a coherent travel plan, allowing passengers to travel on a sequence of flights without needing to check in multiple times for different travel legs.

When tickets are issued with consecutive numbers, it simplifies the travel process for passengers by ensuring that changes to one ticket may affect the others in the series, as they are linked. This is particularly important for fare rules and travel conditions that apply to the entire journey. In essence, consecutive ticket numbers provide a clear indication of a unified travel experience.
