We recommend you use Google Flights to find dates to fly, then book through an online travel agency such as Orbitz or Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using the The Platinum Card® from American Express, you’ll need to book directly with the airline or through Amex Travel portal to get 5x MR points. Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz or Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.We are seeing good fares from a number of US cities to Mexico — including capital city Mexico City and beach getaway Cancun. To book, head to Google Flights and plug in your desired departure city. After finding dates that work best for you, book with the airline directly or with an OTA such as Expedia or Priceline. If you want to make sure that your ticket includes a carry-on bag, you’ll want to use Google Flights’ newest feature, which allows you to filter out no-carry-on fares.Airline: Sun Country, Interjet, Volaris, United, JetBlue, DeltaRoutes: DFW/MCO/LAS/EWR/MCO/JFK/MIA/IAH to CUN/MEXCost: $185+ round-trip in economyDates: May-June, August-NovemberBooking Link: Orbitz, Expedia or directly with the airlinePay With: The Platinum Card from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (5x on airfare plus excellent trip delay insurance) or Chase Sapphire Preferred Card (2x on travel)Dallas/Fort Worth (DFW) to Cancun (CUN) on Sun Country for $185 round-trip:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
