How can I make this program less wordy for eg. with structs and classes and function?

I find that my program is a bit too wordy and im not sure as to how i can make it into less line. Can someone help me please?

Code:

#include<iostream>
#include<string>

using namespace std;
void details( string fNum,int dHour,int dMin,int aHour,int aMin, string aircraft);

int main()
{
 //Flights tB:Trinidad-Barbados,tN:Trinidad to New York,tL:Trinidad to London.
        int dHour;
        int dMin;
        string fNum;
        int aHour;
        int aMin;
        int durHour;
        int durMin;
        string aircraft;
        int rows,columns;
        int dOption;
        bool availabe=true;
        int tbSeats[15][4]={0};
        int tnSeats[32][6]={0};
        int tlSeats[30][10]={0};
        int resAmt;
        int empty=0;

                cout<<"Aircraft is the "<<aircraft<<endl;

}

1)I would do is make a Flight class that contains all the details of a flight. The details function would be a member of Flight

2)You have a lot of code that is Identical except the array which represents the list of seats. Instead of using 3 separate arrays, use one. Either make this array big enough for the biggest plane, or dynamically allocate the correct size array for each flight and use that array.

3)Several times you write a comment like "//This section does such and such". Instead of what you have, for each of those sections make a separate method of Flight with a descriptive name, and remove the comments.

These suggestions may not in all cases decrease the amount of code, but they will make your code clearer, which is generally more important.
