As someone who worked for the Gov't for 9 years, I can tell you that Gov't fares are generally very low (not including the fact they are completely unrestricted and changeable).

Though I don't have a person stake in this matter anymore, I was very happy to see this change. Federal workers get horribly shafted. They don't even get the basics that most employees get. No frequent flier miles even though the airlines will give them to them? Heck, we had to pay for our own water cooler.
