I gather its bidding, as you seem to have forgotten to put the price on.
A name change is for the likes of someone who may of just got married and now has a different name, whereas what you you might need to look at is 'Transfer of ticket to a third party', which is a different thing and is where they usually bump up the price.
The reason I keep harking on about this is simply because sometime ago someone said they got stung with charges as it was not in the airlines opinion a simple 'name change' and what the airlines are trying to do is to stop people buying cheap tickets and then selling them on for a profit.
Charges will be added to update the ticket/s to the current cost on the day of the later transaction.
The only advantage to the buyer is to purchase a ticket on a otherwise 'SOLD OUT' flight.
Have you asked the airline if they would "freeze" your money until you need the flight? We did this with Monarch a while ago. It was just a small charge for "admin".
