The Federal Aviation Administration has put Dallas-based Southwest Airlines on notice, proposing a $304,272 civil penalty and alleging the carrier failed to complete required follow-up drug and alcohol testing for a group of employees. Regulators say those lapses let 11 safety-sensitive workers get back on the job before finishing mandatory return-to-duty checks.
What the FAA alleges
According to the Federal Aviation Administration, the 11 employees included pilots, flight attendants and aircraft mechanics who had previously tested positive for alcohol or drugs such as marijuana, cocaine and amphetamines. The FAA says the alleged failures occurred at various times between August 2021 and July 2024. The agency has given Southwest 30 days to respond after receiving the enforcement letter.
Southwest's response
In a statement to the Houston Chronicle, Southwest said it takes seriously its drug-and-alcohol testing responsibilities and noted that it took steps more than two years ago to strengthen procedures and oversight. The airline said it is working with the FAA while the agency completes its review and repeated that safety remains its top priority.
Why the rules matter
Federal regulations bar crewmembers from performing safety-sensitive duties with a breath alcohol concentration of 0.04 or greater and generally require at least eight hours between drinking and flying, according to the Department of Transportation. DOT and FAA rules also mandate a return-to-duty process and follow-up testing so employees who test positive are evaluated, treated and formally cleared before they resume safety-sensitive work.
Enforcement trend
Trade reports indicate the FAA has been stepping up enforcement actions on drug-and-alcohol testing programs. Aviation outlets have highlighted a March enforcement notice proposing a $65,000 penalty against Avelo Airlines for similar compliance problems. Airways and other industry publications report that regulators are putting a premium on clear, auditable testing and recordkeeping across carriers.
What happens next
The FAA's move remains a proposed civil penalty for now, and Southwest can respond or contest the findings within the 30-day window. The company can try to settle, dispute the allegations or submit additional documentation as part of its reply. The action lands at a time of heightened federal scrutiny of the carrier, including a separate $140 million Department of Transportation penalty tied to Southwest's 2022 holiday operational meltdown, underscoring that regulators are keeping a close eye on both safety programs and consumer protections. Department of Transportation records note the agency's broad authority to seek civil penalties when carriers fall short of legal requirements.
