$247 - Flights from San Francisco to Cancun

This July and August, flights from San Francisco to Cancun Mexico are going for $247 roundtrip. This price includes all taxes and fees.

Mexicana Air offers the cheapest flights to Cancun right now, though flights have either a single or double layover at any of three Mexican airports - Mexico City (MEX) , Huejotsingo (PBC) , or Miguel Hidal (GDL) .

Still, if you have a little extra time on your hands and want to get to the Yucatan Penninsula for under 300 bucks. This should be the way to go.

These flights leave on a number of different days in July and August, but especially earlier in the week, on Mondays and Tuesdays.

From Cancun, I’d personally suggest going south to Carmel or Tulum. If you have even more time, go even further south into Belize, one of my favorite countries in all of Central America or the Caribbean.
