How to create query with twice a connection to a table in Laravel 5.3?

I'm sorry my English is not good.

I need get 2 city name with once query:

For example:

City table:

+---------+----------+
|  Pana   |   Name   |
+---------+----------+
|   THR   |  Tehran  |
|   LON   |  London  |
+---------+----------+

In Model: [from_city is THR and to_city is LON]

public function scopePrintQuery($query, $id)
{
    $join = $query
        -> join('cities', 'cities.pana', 'flights.from_city')
        -> join('cities', 'cities.pana', 'flights.to_city')
        -> where('flights.id', $id)
        ->get([
            'flights.*',
            'cities.name as from_city'
            ??? for to_city?
        ]);
    return $join;
}

Now, I need get from_city name and to_city name this query. In query dose not work 2 join from one table !
