• List all customers stored in the system
• Issue bookings for customers
• Cancel bookings
• Saves status of the system to backend storage (i.e. text file storage)
• Has a number of seats (capacity) property and a price property in the flight object
• Has an email property in the customer object
• Stores data to file storage after execution of commands that change state of the system and informs the user of failure to store the data, rolling back any changes made to the system prior to the error
• Can remove (hide) existing flights from the system
• Can remove (hide) existing customers from the system
• Imposes a limit on the maximum number of passengers that can be added to a flight using the capacity property of the flight object
• Has Javadoc documentation for newer methods
