Booking
Frontier doesn't currently fly nonstop to Mexico City (MEX). The airline serves other Mexican destinations like Cancun, Puerto Vallarta, and Cabo San Lucas, but not the capital. You can reach Mexico City by connecting through Frontier's network to a gateway city and then flying a partner carrier. Mundo Trip can piece together the best connecting itinerary at the lowest price.
Cheapest Months to Travel
Late January, May, and September offer the lowest fares. Avoid Easter/Semana Santa (March/April) and Day of the Dead (late October/early November).
Peak Travel Seasons to Avoid
Christmas to New Year, Semana Santa, and summer (June-August) are peak. Day of the Dead (Oct 31-Nov 2) has become a major tourism draw too.
Best Time to Book
Book 6 to 10 weeks ahead for the best prices on connecting itineraries. Holiday travel needs 2 to 3 months advance booking.
Midweek Advantage
Tuesday and Wednesday departures are cheapest. Weekend flights and holiday adjacents carry premium pricing.
Time Difference to Keep in Mind
Mexico City uses CST (UTC-6), same as Dallas and Chicago. It does observe daylight saving time from March to October.
