Does any United States based airline still operate the Boeing 727 on regularly scheduled flights?

As far as I know, only freight carriers use the Boeing 727. Airlines have phased out the 727 because you need 3 people to fly it while other aircraft only require 2 people. Also the 727 is an older plane and the engines are not as fuel efficient. I have seen FedEx use the 727. UPS has gotten rid of their fleet as my friend who flies for UPS did operate the 727 and now is being trained on the Airbus 300.
