We recommend you use Google Flights to find dates to fly, then book through an online travel agency such as Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using 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 Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.Over all this winter snow? These deals will let you run away to sunny beaches in Western Mexico, even on a post-holiday budget. No special tricks needed for these fares; just use Google Flights to set the dates you want, then book on Expedia or directly with the airline itself.Note that most of these carriers charge additional fees for checked baggage and larger carry-ons, so pack lightly or budget accordingly.Airline: United, Delta, Interjet, Alaska, Volaris, SpiritRoutes: various US airports to PVR/SJDCost: $165+ round-trip in economy classDates: January to May 2018, September to November 2018Booking Link: Expedia or with the airline directlyPay With: The Platinum Card from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (3x on airfare) or Chase Sapphire Preferred Card (2x on travel)Here are a few examples of what you can book:Los Angeles (LAX) to Puerto Vallarta (PVR) for $165 round-trip nonstop on Volaris:Houston (IAH) to San Jose del Cabo (SJD) for $191 round-trip nonstop on United:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
