Delta has round-trip flights from Austin (AUS) to Liberia, Costa Rica (LIR) for $345 with a connection. Flights April, May, September, November, December, and January. Departures on Monday, Tuesday, Wednesday, and Sunday. Origin/Destination reversible. Holiday blackouts.

A Carry-on bag and also a personal item is allowed for free on Delta. 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.

There is currently a limited time offer for Delta’s co-branded credit card with a higher than normal welcome offer! (the card offer ends 04/02/2025) Visit our Delta credit card landing page for the current sign-up offer and more details (link).

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

Don’t miss out: The bonus offer on the Capital One Venture Rewards Credit Card has recently been increased to $250 Capital One Travel credit and 75,000 miles after $4,000 in purchases within the first 3 months of card membership! This is equivalent to about $1000 worth of Travel value and beats the previous offer that was worth $750 of travel value.

Do a search on Tripadvisor and GetYourGuide to find guides, tours, attractions, and cool things to do. I use both of those sites to help me plan my own day-to-day itinerary while on vacation.

We post new flight deals often! You can check out our other deals by returning to the Front Page of our website: escapeatx.com (linked).

Here are some other offers that we think are worth mentioning. List updated 03/25/2025.

We now track coupon codes, discount codes, gift card discounts, and credit card offers that have a better value than their historical averages.

  • Airfare/Hotel coupons on Hopper: (updated daily-ish) Hopper always has discount coupons on their main page. The full list is on Hopper’s website. Keep in mind that Hopper is an OTA, so don’t expect them to honor the free 24-hour cancellation period, or to have the lowest base fare price. Hopper will try to up-sell you on a lot of extras like “cancel for any reason” policies, if you decide to use Hopper we advise that you decline all of those extras.
  • It is common to find Southwest and Alaska Airlines 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 on either of these airlines, you should check to see if you can save more money by using a gift card.

  • 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.
