is there a way to use a variable in another method without using a parameter?

there is a variable called (limitOfPassengers) in the first method called (addFlight), asking the user to enter a number for the limit then save it in the variable. then i want to use this input in another method called (addPassengerToTheFlight) with an if statement to check if the added passengers doesn't exceed the given limit number.

if i use a parameter in the second method there will be an error on a switch method. What should i do?

The code is too long but here are the codes issue

 switch (choice) {
                case 1: {
                    airway.addFlight();
                    break;
                }
                case 2: {
                    System.out.println("\t\t\t\tPlease Enter Detail of Passenger");
                    airway.addPassengersToFlight();
                    break;

                }
// the first method
public void addFlight()
    {
int limitOfpassengers;
System.out.print("Enter passenger limit:   ");
        limitOfpassengers=ss.nextInt();
}

//the second method

    public void addPassengersToFlight() {
if (flight.getPassengerLimit() <= limitOfpassengers) {
                flight.addPassengers(passengers);
                System.out.println("New Passenger is Added!");
            } else {
                System.out.println("!!!No More Space for Passenger!!!");
            }
}
