Frontier Airlines is offering flights to destinations across the country starting at $20. The $20 one-way flights are available on routes including Albuquerque to Denver, Atlanta to Orlando, Austin to Indianapolis, Chicago to Charleston, and many more. There are also deals to San Juan, Puerto Rico, starting at $33 one-way from Miami. Return flights are also cheap, and there are round-trip fares available for less than $50. The Frontier sale runs through Wednesday, May 9, and the cheap flights are available for travel from May 11 to June 6. Frontier is a budget airline, so seat selection and baggage cost extra. Depending on what extras you'll need on your trip, it could make sense to purchase a bundle. Make sure to check any and all fees before purchase so you really do get a great deal.
