This is called a companion flight and you have to phone the flying club to see if there are any. You also have to pay the taxes, plus a full flight fare for yourself. If you are going off peak, you may get lucky.
Thanks, I understand I have to pay taxes on the free fare but will the paid for fare be the fare published on the website? when it was mentioned before I think someone said it would the dearest seat code you would need to pay for.
