A former United Airlines pilot who joined the Chicago-based carrier in 2023 after spending 13 years serving the United States as a decorated C-130 combat pilot in the Air Force is now suing the airline for race discrimination and retaliation after he was terminated for refusing to enter a substance abuse treatment program.
The pilot started flying with United Airlines as a First Officer in March 2023, but just a few months later, he was arrested on suspicion of DUI following a traffic stop and a failed field sobriety test in Montgomery County, Texas.
Law enforcement never took a blood draw, which would have confirmed whether the pilot was actually over the alcohol limit, and the charges were later dismissed. Nonetheless, the pilot followed United and FAA protocols by immediately reporting his arrest.
Within days of reporting his arrest, the pilot claims United started to pressure him to enter a substance abuse program designed for pilots who have been diagnosed with alcoholism.
According to a new lawsuit filed in a Southern Texas district court, United acted as if the pilot was an alcoholic – a claim that the pilot denies and even got an independent psychiatric report to show that what happened in July 2023 was a “one-off, aberrant event.”
The pilot pushed back on United’s insistence that he should enter the so-called HIMS program, which requires pilots to attend regular Alcoholics Anonymous meetings, arguing that this was unnecessary.
When the pilot refused to enter the HIMS program, United terminated his employment, although the carrier used the temporary loss of his FAA medical flying license as the pretext for his dismissal.
The lawsuit makes the point that while pilots with actual substance abuse problems have been allowed to keep their jobs at United, he was sacked for a single mistake that didn’t even lead to criminal charges being pursued.
The pilot alleges that another crew member arrested for DUI shortly after his own arrest was allowed to keep his job because he enrolled in the HIMS program.
“United’s perception of Mr. Castillo as an alcoholic was not a neutral medical judgment but reflected racialized stereotypes about Hispanic men and alcohol use,” the complaint reads.
“These intertwined biases—viewing a Hispanic pilot’s single arrest as evidence of addiction while extending leniency to White pilots for comparable conduct—amplified the discriminatory motive underlying United’s decision.”
The lawsuit further alleges that United then reported to the Federal Aviation Administration that he had been terminated due to “pilot performance issues” – a report that he says is a “stigmatizing designation” that was only withdrawn when he brought in a specalist attorney to fight his case.
The pilot is fighting for his job back, as well as back pay for the time he has spent unemployed at United.
In 2022, United agreed to a $305,000 settlement in another lawsuit centered on the HIMS program. In that case, an alcoholic Buddhist pilot said attending Alcoholics Anonymous meetings was not appropriate as the program is rooted in the Christian faith.
The famed AA 12-step program includes specific references to a Christian God and acknowledgment that a “greater Power exists”. As a Buddhist, the pilot didn’t share these beliefs and felt uncomfortable beginning every session, held in a church, with a Christian prayer.
The pilot requested to swap the AA meetings with regular attendance at a Buddhism-based peer support group, but United Airlines refused.
The latest lawsuit is filed under case number 4:25-cv-04881 in the district court for the Southern District of Texas.
