Which of the following is NOT a type of baggage designation mentioned in Delta ramp operations?

In Delta ramp operations, the designation of baggage plays a crucial role in the efficient handling and processing of passengers' luggage. Among the listed types of baggage, express bags are not typically recognized as a standard classification within Delta's operational framework.

Local bags refer to those that are checked in for a flight and remain within the local travel area, while priority bags are given expedited handling due to specific passenger preferences or status levels. International bags are those that are set for travel between countries and may require additional processing due to customs and regulations.

In contrast, express bags, while they may sound like a designation that indicates speed or urgency, are not categorized within Delta's baggage designations. The terminology used in ramp operations primarily focuses on local, priority, and international classifications, making express bags an inaccurate choice in this context.
