My first reaction is:
Nice Domain! But Oveture Stats weren't as huge as I'd Expect:
2498 discount fare
1867 discount airline fare
Looks like the searches are more on:
62775 discount travel
Having said that. It's two word domain which is nice, easy to remember. By itself probably you could pull $50-$150 but if you put some time in to it, got some traffic up, key spots on search engines I thing you could find the value being 4-5x that.
my 2 cents
