Here are some other offers that we think are worth mentioning. List updated 11/18/2024.

We now list 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: The Chase Sapphire Preferred® Card allows for 1-to-1 point transfers to several airline loyalty programs. Booking with points is a good alternative to paying with cash when the price of airfare is high. Here is the current list of Chase Sapphire transfer partners: United, Southwest, jetBlue, British Airways, Iberia, Singapore Airlines, Emirates, Air France, KLM, Virgin Atlantic, Aer Lingus, and Air Canada.
  • 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.
