Are you saying that you could book on one flight, monitor C class availability, then close to your departure date, switch flights to one that has availability? Would you have to pay a change fee to do that?</font>
On a discounted ticket, you can't change the outbound segment just by paying a change fee. The whole ticket has to be repriced. That's why it's better to hold off booking until closer to departure time when you can get a better idea of the availability of C class.
