    (SELECT a.departure, a.arrival, 0, price
            FROM flights a 
            WHERE a.departure = 'Chicago' OR
                  a.departure = 'New York'
     UNION ALL 
     SELECT r.departure, b.arrival, r.connections + 1,
                  r.cost + b.price 
            FROM destinations r, flights b 
            WHERE r.arrival = b.departure) 
SELECT departure, arrival, connections, cost 
       FROM destinations
