Ask HN: Would you use a periodic travel ticket search engine?

What I mean by this, suppose you want to go home for a weekend but you don't necessarily care which weekend as long as it's cheap.

I have built a small script which searches every Friday to Sunday train and flight tickets for 4 weeks and gives you the cheapest fare for a weekend.

Right now it's a command line script and I was just wondering if anyone else would find it useful?
