Frontier Airlines is having a two-day sale. Tickets must be purchased by 11:59 pm Eastern time on Apr. 16, 2015. They have flights starting at $39 from many of the cities they fly from, but the deal is available for domestic, nonstop travel on: Mondays, Tuesdays, Wednesdays, Thursdays, Saturdays, Apr. 30, 2015 through February 27, 2019.
These cheap flights won’t help towards any major elite status, but you can still get extra credit card points by using a card that maximizes airfare purchases, such as 3x on airfare with the American Express Premier Rewards Gold or 2x on the Chase Sapphire Preferred. Make sure to book now as seats usually go fast.
