United Airlines could furlough 36,000, or 45 percent, of its U.S.-based frontline employees by Oct. 1, the company announced Wednesday.

Airlines that received government loans were forbidden from furloughing or laying off employees until Sept. 30 under the terms of a  $2.2 trillion federal coronavirus stimulus package aimed at helping airlines retain staff as the pandemic crushes the travel industry.

"None of the decisions we've made so far have been more difficult than the decision we are announcing today," a United official told reporters during a Wednesday press call.

United estimates that furloughs could impact 11,000 airport operations employees, 15,000 flight attendants, 5,500 technical operations employees, 2,000 flight operations employees and hundreds of other workers in catering operations, contact centers and network operation centers.

Another official added that the company decided to announce the potential furloughs to employees today to allow its teams "as much time as possible" to think about the impact furloughs will have on their careers. Read more at FOX Business
