Below is the layout for the EER diagram:

Passenger: $($PassengerID$,$ Name, ContactNumber, Email$)$

Flight: $($FlightNumber$,$ DepartureTime, ArrivalTime, DepartureLocation, ArrivalLocation$)$

Specializes into: DomesticFlight, InternationalFlight

Airline: $($AirlineID$,$ AirlineName, Headquarters$)$

Reservation: $($ReservationID$,$ ReservationDate, Status$)$

Airport: $($AirportCode$,$ AirportName, Location$)$

Ticket: $($TicketID$,$ Price, SeatNumber$)$

Relationships:

Makes: Passenger to Reservation

Includes: Reservation to Ticket

Operates: Airline to Flight

ScheduledAt: Flight, Airport, Time $($ternary$)$

BelongsTo: Ticket to Flight

Using this structure, we can now draw the actual EER diagram. Here is a detailed diagram:

Passenger $($PassengerID$,$ Name $[$First Name, Last Name$],$ ContactNumber, Email $\{$multivalued$\})$

Flight $($FlightNumber$,$ DepartureTime, ArrivalTime, DepartureLocation, ArrivalLocation$)$

DomesticFlight, InternationalFlight $($Specialization$)$

Airline $($AirlineID$,$ AirlineName, Headquarters$)$

Reservation $($ReservationID$,$ ReservationDate, Status$)$

Airport $($AirportCode$,$ AirportName, Location$)$

Ticket $($TicketID$,$ Price, SeatNumber, FlightNumber, PassengerID$)$

Relationships:

Makes $(1,$ N$)$: Passenger to Reservation

Includes $(1,$ N$)$: Reservation to Ticket

Operates $(1,$ N$)$: Airline to Flight

ScheduledAt $($Ternary$,1,$ N$,$ N$)$: Flight, Airport, Time

BelongsTo $($N$,1)$: Ticket to Flight

By following these steps and using the example diagram given, we have outlined an EER diagram for an airline tickets reservation management system.
