You Can Score Tickets to Mexico or the Caribbean For Just 100 Miles With This U.S. Airline — What to Know

Booking a Caribbean or Mexican getaway just got cheaper. 

Frontier Airlines recently announced a special promotion that drops the number of miles for a one-way flight to international destinations from the United States to only 100 miles, whereas it usually is 15,000 miles. Best of all, the discounted mile redemptions also extend to select domestic routes, with one-way flights available at 2,500 miles versus the regular 10,000 miles. 

The promotion runs through January 24, 2025, giving travelers extra time to plan the ultimate vacation to the Caribbean or Mexico. Travelers can book the deal on Frontier’s website. 

Frontier offers service to a variety of Caribbean destinations including:

• Antigua and Barbuda, Belize
• Guatemala City, Guatemala
• Kingston, Jamaica
• Liberia, Costa Rica
• Montego Bay, Jamaica
• Nassau, Bahamas
• Punta Cana, Dominican Republic
• San Jose, Costa Rica
• San Juan, Puerto Rico
• San Salvador, El Salvador
• Santo Domingo, Dominican Republic
• St. Thomas, U.S. Virgin Islands
• Sint Maarten (Saint Martin)

The airline also operates other international services including Cancun, Cabo San Lucas, and Puerto Vallarta in Mexico, which are also included in the fare sale. 

While the offer is enticing, travelers should be aware of the terms and conditions for the sale, which include limited dates that tickets can be booked. For example, the reduced redemptions are not available during popular spring break travel dates such as April 4-6 or April 11-13, and all tickets are subject to taxes and fees. The tickets may also cost more due to baggage or seat assignment fees. 

The Denver-based airline has been on the move with customer enhancements, including recently reducing the threshold to achieve loyalty status, and announcing a new first class cabin. 

Frontier is the latest airline to offer discounted flight deals for the start of 2025. American Airlines recently announced discounted Europe tickets under $500, and Air France/KLM’s Flying Blue loyalty program has discounted Europe award tickets to 15,000 miles.
