Everyone loves a fare deal. Sites like Airfarewatchdog.com have sprung up to help fill this insatiable need, and now another site, TheFlightDeal.com, automatically sorts airfare, vets the deals, and publishes them. The site even posts a list of “bad” deals and offers useful booking tips. Deals are also posted to social media, and readers can sign up for a free newsletter. If a deal is more than two days old, it’s probably no longer available, the editors warn, adding that they plan to double the site’s size in a year, covering more cities with more real-time access for frequent flyers.
