Your task is to give feedback on the statement given provided context.\n    Here is the context: Flight, Booking, Airline, Airport, and Passenger are the entities in the environment.\n Each flight departs from a specific airport and arrives at another one, therefor flights have two different relationships with the airport. In this environment, we only model direct flights. Each flight has a flight number and maximum passenger size. Many flights depart from one airport and many flights arrive at one airport however one arriving flight is associated with only one airport and one departing flight is associated with only one airport.\n A flight may be scheduled by different bookings. Each booking must have at least one flight therefore, the booking must have a total participation relationship with the flight. we can say flight has booking or booking includes flights. \n A booking identifies by booking id and has a total cost. An airline schedules different flights and one flight may be scheduled by different airlines. each passenger must have one or more bookings, so we don't define a passenger unless he/she has at least one booking, so the passenger has total participation in the relationship with booking. Booking must also be associated with one and only one passenger so booking also has a total participation relationship with booking. A passenger makes bookings and booking holds by passengers.\n  \n    Passenger has not any relationship with the airport in this environment.\n    Statement:\npassenger has many-to-many relationship with airport\n   You should write your response with 600 or more words.
