Sorry if this has been posted before. I did a search first and couldn't come up with the answer I was seeking. I booked our tickets for our April trip a couple weeks ago and today the price went down $50. If I'm understanding their website correctly all I have to do is cancel my reservation and then they issue me a credit and then I take that credit and use it to re-book the same flights at the lower rate and then I'll have a credit leftover to use towards a future reservation? Is that right and how long does it take to get the credit? I would like to re-book right away so I don't lose the lower fare. The new fare is not a Ding fare, I don't know if that matters or not. Any help with this is greatly appreciated.
