Heads up, deal hunters! The Flight Deal has spotted some seriously cheap flights to and from Las Vegas. We're talking around $171 for regular economy. This is a "good sale", meaning that the price is significantly lower than the average fare, but can still be further discounted if you know how to search. To snag this deal, they recommend using the Matrix Airfare Search by ITA Software. It's a powerful tool that lets you search for the absolute lowest fares, but be aware that you cannot book directly through Matrix. Once you find your dates, you'll need to head over to an online travel agency (like Expedia or Priceline) or directly to the airline's website to book the flight. Why should you care? Well, Vegas flights are rarely this cheap, especially outside of the off-season. If you've been dreaming of hitting the Strip, catching a show, or just soaking up the desert sun, now's your chance to do it without breaking the bank. This is also a great opportunity to use your travel rewards for hotels or entertainment, since you'll be saving so much on the flight itself!
