It also depends on where you bought the ticket and if it has been used. If it is an unused ticket, then you only get credit for what you paid for it. So, if you bought it at a disocunt, then you don't get the gate price for it. However, if you use a day off it, then you would get full gate price for it as long as you're in the 14-day window from first use.
Chesire Figment can tell you for sure, but I'm pretty sure that's how it works.
