AwardWallet.com is an invaluable tool for us frequent travelers to track of our travels, miles, points, etc. It supports hundreds of airlines, hotel chains, rental car agencies, and other travel-related programs. Delta forced AwardWallet to stop allowing us to track our Delta travel. We, AwardWallet users, specifically chose to use AwardWallet to track our travel. Why would Delta disallow this? If Delta wants to keep its loyal Medallion members, it will reverse this decision.
