The same bot, DoNotPay, that helped users overturn parking tickets and sue Equifax for small sums of money is now offering you protection against volatile airline prices. The Verge reports: Joshua Browder, a junior at Stanford University, designed the new service on the bot in a few months, after experiencing rapidly fluctuating airline prices when flying to California during the wildfires last year. "It annoyed me that every single flight, I could be paying sometimes double or even triple the person next to me in the same type of seat," he told The Verge. Browder first used the service himself and then tested it among his friends in a closed beta. He claims that the average amount saved among the beta testers is $450 a year, though it's not clear how many flights were booked and how much they cost. The service is available to the public starting today. To use it, log in with a Google account, input your phone number, birthday, and credit card information through Stripe. (Browder swears the credit card information won't be stored.) Then the chatbot tells you you're all set. Now, every time you buy airline tickets, whether from an airline's site or a third party, the chatbot will help make sure you pay the lowest price for your class and seat.
