Q2: What is the worst performing High Frequency Route in terms of EWT (Estimated Waiting Time)? Q3: What is the best performing Low Frequency route in terms of On Time and QSI points? Q4: What is the worst performing Low Frequency route in terms of On Time and QSI points? Q5: What route has the most operated mileage?
