Ok so how do I go about finding a cheap seat to BCN? Am I trying to book too far out? LH/OS/AC from YYZ all come in at $4000 - $5000 bucks! I want to rent the seat, not buy it. Is the trick buying a ticket to FRA or LHR and then hopping a separate plane to BCN? (I am looking at Oct out, back on the 5th).
