Hi, I'm thinking about sending my mom standby on Continental from ROC-EWR, EWR to PHX. I have checked the loads on employee-res system and they seem fairly good. I'm wondering how accurate this system is.

Skynet will often say a flight is oversold only to have 30 plus seats open, or make it seem the flight is wide open and one hour later it's oversold. I realize there can be offloading, delays and cancellations but I'm just trying to get a general idea of how reliable the numbers are on employee-res. Thanks in advance for any input.
