Q5) The following table (Modify some departure and arrival times) shows flight schedule for a B757-200. Generate a five-day valid routing with minimum 20 utilization hours in 5 days according to the following criteria: It starts and ends at the same city. Each day, flights start at the city where the aircraft ended the day before. An overnight stay at JFK occurs at least once. Turn-around time is 30 minutes. Routing in each day should be differdnt from the other days. Flight no.
