Look up comparable sales of domains ending in "LY" or (better yet) .LY.
It has been a very popular naming trend. And travel is a big industry.
I wouldn't be shocked to see a good-sized $x,xxx sale or even $10k or more -- as a best-case scenario.
As a domainer, I wouldn't pay anywhere near that much wholesale. But I MIGHT be interested if you decided to let it go cheap.
