If you're a regular airport warrior like me, then you'll love this new web service. Called Flyspy, it's one of those tools which will leave you wondering how you ever did without it (especially if you work for an SME/SOHO and you watch those expenses carefully).
Reviewed by Nik Cubrilovic who's standing in for Techcrunch's Michael Arrington whilst he's on holiday (I wonder whether he used this service?), you tell Flyspy your departure and destination airports and it returns the cheapest ticket prices AND the days in a handy graph.
I'm sitting here waiting for the service to go live (keep watching their website!), imagining how much wear and tear it'll save on my Back button, and my wallet, when booking airline tickets.
