Frontier is having another one of their crazy, cheap $19 fare sales and there are tons of options for roundtrip fares for only $38 including taxes! I searched around for a minute and found tons of availability.
Crazy Cheap Flights $1.70 Airfare + Tax = $38 RT
As an example, ATL to PHL, airfare $1.70+ $36.30 in taxes = total $38!
- Use promo code 5OFF
Consider checking for a cheap flight for Thanksgiving with this sale that is bookable through October 14th. Use promo code 5OFF and be sure to use a card that will earn you bonus points on your airline purchase, like the Premier Rewards Gold Card from American Express which earns you 3X points for flights booked with airlines! You can read all about the additional new benefits of this card here, like the new $100 airline fee credit!
Of course Frontier has several additional fees for baggage and more but, at $38 it might still make sense for you.
