AA 20% off sale to New Orleans, Orlando, and Vegas

American Airlines is taking a page out of Southwest's play book by launching sales that can only be booked on American's site.

They're offering 20% off flights between the lower 48 states and Las Vegas, New Orleans, and Orlando until Monday. Use promo code DFGHOST when booking on www.aa.com. Travel Oct 29 to Nov 14 only, and please note that all advance purchase restrictions apply, meaning that you'll get the lowest fares if you start your travel 14 days ahead of date of purchase. We found, for example, New Orleans to Las Vegas for $221 plus tax leaving Nov 9 and returning Nov 13 or 14, a savings of $56 RT. This sale ends on Oct 29, midnight CT. Some routes are excluded from this sale.
