In the comment you are replying to, I specifically said "I have to re-use them within 12 months, and the airline deducts a change fee from the value before making the deposit." Changeable with a fee is not the same as non-changeable. Yes, there's a penalty, but if the original ticket was $500, you can still re-use more than half of the value.

Even on fully changeable tickets, with no fee, you can't assign them to another passenger. You'd have to have a refundable ticket, get the refund, and then buy another ticket.

But I don't think I ever implied differently?
