Has anyone ever done this..?
Purchase a ticket (Y class) -which has a penalty for cancellation.
A week later, a cheaper fare shows up - can one then cancel the original ticket, and buy the cheaper fare (including the penalty, the price still works out cheaper)..?
This is CX specific - but presumably would apply to all other airlines?

Or is there a way to move to the lower fare (can the travel agent through whom this was done help in this) without cancelling and re-purchasing?

Thanks!
