Design a product for air travelers.

Focus on identifying the specific pain points that air travelers face, such as long security lines, flight delays, or baggage handling. Consider the entire travel journey, from booking to arrival, and think about how your product can enhance convenience, comfort, or efficiency. Be prepared to discuss user personas and how your design addresses their needs. Additionally, consider the feasibility of your product in terms of technology, cost, and integration with existing systems in the airline industry.
