Thanks for the reply SB12! I knew better on the change fee, but forgot.

I have been reading the very long threads in the other forum and came across this information. Please see post #436 in this link where the poster claims that on CO you can only use the residual ticket value for one additional ticket. Do you know if there has been a recent change, or perhaps you really can only get one additional ticket? Have you ever used the residual value for more than one ticket?
