Most, if not all, U.S. carriers are similarly enlightened and have been since circa 1980. But, all bets are off if a pilot reports for duty intoxicated. That is automatic termination.
If the pilot was "turned in" off duty, then the company would keep him/her on full pay and send him/her to a first-rate 30-day recovery facility. Then, the pilot had to be monitor for several months afterward.
