Checked bag fees start at $25 each way. 

Frontier also has a promo code for travel to Florida or Las Vegas. Using the promo code SAVE75 on FlyFrontier.com will discount travel to Florida or Las Vegas on Sundays, Mondays, Tuesdays, and Wednesdays, from April 3 through May 9. Promo code expires at 11:59 pm ET, on March 21.

Flights from Florida or Las Vegas will not be discounted so you'll only see a price drop in one direction if you're traveling round-trip. Also, the discount does not apply to taxes nor Frontier's online booking fee, which they label a "Carrier Interface Charge". This means some routes still won't have a very big price drop. As always, Frontier has a long list of specific routes that are excluded from the promo code sale.
