I got $5 credits from Song last month. They applied a $25 per person charge for making the change, and gave me the difference, one in each person's name. Now I have a 12 year old with little chance of flying within the next year holding a $5 credit. If I had known the flights were going to decrease in price again, I would have waited and gotten a bigger credit. Now it's not worth calling again, the $25 charge would more than eat up the credit. Live and learn, at least I was happy with my original prices so the rest is all gravy.
