New travel deals for Amazon Prime members on cruises, rental cars, flights and more

Amazon Prime Day is fast approaching, and beyond viral beauty products or hot new kitchenware, the e-commerce giant is introducing savings on travel just in time for any last-minute summer vacations.

Amazon partnered with various travel companies, including Southwest Airlines, Viator, Turo, Carnival, and others, to give Prime members early access to price cuts on travel packages, car rentals, and cruises.

In a similar move last summer fellow retail competitor Walmart partnered with Expedia to give Walmart+ members the ability to earn Walmart Cash by booking vacations.

"These travel deals are sort of an extra that they can offer their members," RetailMeNot editor Kristin McGrath told ABC News. "There are plenty of ways you can save and get discounts. These membership programs can just make it a little bit easier."

Costco travel discounts and deals

The warehouse retailer's travel arm offers everyday savings on top-quality, brand-name vacations, hotels, cruises, and rental cars, exclusively for Costco members.

Teresita Nino has used Costco to book vacation packages and told ABC News how she saved on international deals.

"My last trip that we booked was to Saint Lucia and we ended up booking the airfare and the hotel -- I ended up saving about $700," Nino said of her experience using Costco. "Nine out of ten times is Costco Travel is always giving me a better deal overall than other travel companies."

Access to Costco's travel deals require a paid membership as an extra perk for customers.

"The travel savings are the cherry on top -- but it's not necessarily the most lucrative benefit," McGrath said. "In these membership programs, you have to take the value of membership as a whole rather than just joining to save on travel."
