My son is in a division where everyone is goofing off, he is one of the leaders and doing great!! passing his tests as required. the problem is that due to the rest of the division, the graduation for this group may be delayed. The CO is trying to get my son into another division so he can graduate on time. I know I was told to buy refundable tickets but I did not, knowing how my son is, what I did not expect was how the others were going to be. I did buy ticket insurance though and I know I can change my flight date for a fee of course. Anyone have any input on this or experience?
