United warns of cargo disruptions as it reviews fleet options following 777 incident

United has warned of possible disruptions to its cargo flight schedule in March as it juggles its fleet after its decision to ground 24 Boeing 777-200 aircraft, according to a notice sent to cargo customers. United temporarily removed the 777-200 planes from service after an engine failure on Saturday forced an emergency landing on a passenger flight soon after take-off. “As we review options for swapping aircraft in for scheduled passenger flights, we will be readying planes that have been parked in storage, reconfiguring some cargo-only flights to return to the passenger schedule, and modifying the March cargo flight schedule,” United Cargo said in the notice on its website, posted late Monday.<br/>
