Hi @MisterRickH, AARP members do not get discounts on flights booked through Expedia as AARP members only get discounts with companies who have a contract with AARP. The AARP Travel Center allows members to book with AARP providers as well as non-AARP providers just like the regular Expedia website. This is to provide members with the ability to comparison shop. AARP does however, partner with British Airways to provide flight discounts. With British Airways, AARP members save $65 off World Traveller (economy) and World Traveller Plus (premium economy) or $200 off Club World (business class) fares when you purchase round-trip transatlantic tickets on the British Airways website.
To see the full list of providers who offer discounts and benefits to AARP members, visit the Member Benefits page: https://www.aarp.org/MemberBenefits. When viewing the page, click on the name of the benefit (like Avis/Budget under the Rental Car section, for example) to learn more about what is included and to get started with using the benefit and/or discount. If a company is not listed on the AARP Member Benefits page, then they do not have a partnership with AARP. I hope this helps to clarify!
