It’s Frontier, so the nickel & dime cattle car experience, but if you’re going for cheap flights, can’t imagine how you can beat this at 99% off. Promo code NEWYEAR.
T&Cs say 1/1/2020 but there’s a timer on the site that looks like it will expire around 8pm Mountain. I wouldn’t assume the promo code will be valid after that.
