How would you improve the worst post-booking experience at an airline?

Focus on identifying specific pain points that travelers face after booking a flight, such as confusion over itinerary changes, difficulty accessing customer support, or lack of communication regarding flight status. Consider the entire post-booking journey, including pre-flight reminders, check-in processes, and any ancillary services that could enhance the experience. Propose concrete solutions that leverage technology, such as a mobile app feature for real-time updates or a chatbot for customer inquiries. Be prepared to discuss how your improvements would impact customer satisfaction and retention, and consider the feasibility of your ideas within the airline's existing infrastructure.
