is celebrating its fourth anniversary by slashing rates on every flight by 50 percent. This under-the-radar domestic carrier provides non-stop flights to 15 destinations on the East Coast and in the Midwest including Niagara Falls, Fort Myers, Myrtle Beach, Pittsburgh, New York (Newark), Chicago, and more. Never heard of this Myrtle Beach-based airline? Direct Air's flights are public charters operated by Virgin America and USA Jet – so it's unlikely that you'll see it pop up in an airfare search on most major websites. Although Direct Air’s route network and flight schedules aren’t as robust as that of other domestic carriers, its flights are often significantly less pricey. This new fare sale cuts rates to just $55 one-way on select routes, but tickets must be purchased by March 7. Use promo code EMDA24 when booking.
