If winter just isn’t your thing, you’re in luck. An all-out airfare war between United Airlines and Delta Air Lines has resulted in $230 round-trip flights to popular resort towns in western Mexico.

Friday morning, Thrifty Traveler announced that cheap seats to Puerto Vallarta and San Jose del Cabo were available from a number of U.S. cities.

The most inexpensive seats ($230 round-trip) can be found on flights originating in Atlanta, Cincinnati, Detroit, Minneapolis, Salt Lake City, San Francisco, Seattle, and San Diego. But affordable flights can also be found from Los Angeles and Santa Ana.

East Coast-based travelers, meanwhile, can score $272 round-trip flights from two Washington, D.C.-area airports.

Flights to Puerto Vallarta and San Jose del Cabo can be found from January until May, but we wouldn’t wait to book these tickets. Upon arrival at one of the region’s luxurious all-inclusive properties, all thoughts of icy winter temps will quickly melt away.

To book, travelers should use Google Flights to identify the most inexpensive days to travel from their preferred airport. To score even steeper savings, enter those travel dates into a search engine like Momondo or Skyscanner, which can locate tickets from third-party retailers.
