Southwest, American, and Delta have round-trip flights from Austin (AUS) to Sint Maarten (SXM) for $323-$357 with a connection. Flights June to March. Very few weekends available. Origin/Destination reversible.

Delta allows one carry-on bag and one personal item for free. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.

If you travel on Delta often, consider getting their credit card. Most of their cards allow for a free checked bag perk and a 15% discount on points redemptions.

Use a card like the Southwest Rapid Rewards® Plus Credit Card to earn points towards a Companion Pass®. Companion Pass is the benefit that allows you to choose one person to fly with you, free of airline charges* every time you purchase or redeem points for a flight. *Companion Pass doesn’t cover taxes and fees.

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.

You can usually save more money by booking your flight+hotel together as a package instead of separately.

  • Tips: Rent a car for cheaper by using Priceline’s “Express Deals”. The rental car company will be hidden until after you purchase, but this allows those companies to undercut the published rate indirectly. You can remove low quality companies from those hidden results. The trick is to use the quality filter on their website to remove any rental car company with a review rating under 7.0 and then pick the deals that survive the filter. Note that the quality filter is only available on the desktop/web version of the Priceline website and isn’t available on the mobile version.
  • 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.
