How do I use methods in a module script?

Hello,

I would like to find a way to get this method which is supposed to output a table with the raw string values of each airport name to work. Currently not even the method is being triggered/fired.

I would greatly appreciate any help.

My module script:

local airport = {}

airport.destinations = {
    Zakynthos = {
        Name = "Zakynthos";
        IATA = "ZAK"
    }
}

airport.airlines = {
    Airline = {
        Name = "Airline";
        GroupID = 1;
        IATA = "AA";
        Destinations = {
            airport.destinations.Zakynthos;
        }
    }
}

for i, v in ipairs(airport.airlines) do

    function v:GetDestinations()
        print("method fired")
        local dest = {}
        for _, x in ipairs(v.Destinations) do
            table.insert(dest, x.Name)
        end
        return dest
    end

end

return airport

Script

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local dest = airportData.airlines.Airline:GetDestinations()

for i, v in ipairs(dest) do
    print(v)
end

Thank you!
