​Limit orders on plane tickets

There should be a feature where you can pick out the plane tickets, dates, cabin, and filling out all your information as usual but instead of paying right away you can set a limit order of how much you’re willing to pay, like how you would with stocks and ETFs. Then your ticket order will auto fill if/when the airline drops the price to that amount. I know you can set price reminders on Google but those usually slip by me. Autofill order would be hella nice for booking these far out international trips.
