It is common to find Southwest gift-cards for sale at a discount of about -$70 to -$20 off the redeemable value at Costco and Sam’s Club. Before you finalize your booking you should check to see if you can save more money by using a gift card.

Southwest Vacations usually has discounted package deals available that can save you more money. Package deals require than you book your flight + hotel together as a package, so it’s less flexible, but the package discount may be significantly cheaper than booking your flight and hotel separately.

  • Tips: Use Tripadvisor to create a Hotel “short list”. First, plug in your dates and destination. Then select “Sort by Traveler Ranked”. Finally, select the “Traveler Ranking” filter to show “only 4* and up”. Use this resulting “short list” of hotels to find the cheapest one with a high ranking.
  • Tips: Hotel rates for Weekend dates are usually higher than the rates for Sunday through Thursday. Tripadvisor has a color-coded date calendar, red when the average hotel price for that day is more expensive, green for less expensive. You can use this to get an overview of what dates in the month are at a discount.
  • Tips: Different booking websites will often have differing routes, prices, and availability. Before you finalize your purchase, do a quick check on BookingBuddy, Skyscanner, and Kayak to see if any other site or airline is offering a better deal.
