The United States Federal Aviation Administration (FAA) has proposed significant financial penalties against two major carriers. American Airlines and Southwest Airlines both face fines. The regulator cited serious lapses in their airline drug and alcohol testing programmes.

The proposals came in early April 2025. They raised fresh questions about how rigorously commercial airlines enforce safety rules for workers responsible for millions of passengers each year.

FAA Moves Against American Airlines Over Drug and Alcohol Testing

On 8 April, the FAA proposed a civil fine of $255,000 (approximately £202,000) against American Airlines. The regulator cited repeated breaches of federal testing requirements spanning more than four years.

Between May 2019 and December 2023, American Airlines allowed 12 flight attendants to resume safety-sensitive duties. Each had previously returned a positive result in aviation substance testing compliance checks. None had completed all required follow-up testing before returning to work.

American Airlines said it was reviewing the FAA notice. “The safety of our customers and team members is paramount. We take drug and alcohol testing seriously and collaborate with the FAA to address any issues,” a spokesperson said.

Southwest Airlines Faces Larger Penalty for Aviation Substance Testing Failures

Two days later, on 11 April, the FAA turned its attention to Southwest Airlines. The regulator proposed a steeper fine of $304,000 (around £241,000). Southwest allegedly failed to conduct required follow-up testing for 11 employees. That group included pilots, flight attendants, and aircraft mechanics.

Those employees had previously tested positive for alcohol or controlled substances including marijuana, cocaine, and amphetamines. During various periods between August 2021 and July 2024, they continued performing safety-sensitive functions. Southwest had not subjected them to the mandatory rounds of airline drug and alcohol testing that federal rules require.

Southwest insisted it takes its testing obligations seriously. The airline also noted it acted before regulators intervened. “We took immediate action more than two years ago to enhance our procedures and to strengthen oversight and accountability,” a Southwest spokesperson said.

Why Airline Drug and Alcohol Testing Compliance Matters

The stakes in aviation are high. Impaired judgement at 35,000 feet, on a runway, or in a maintenance bay can be catastrophic. Airline drug and alcohol testing rules exist to protect the travelling public, not to fill paperwork.

Under the FAA’s framework, any employee who tests positive must complete a structured return-to-duty protocol. A substance abuse professional must evaluate them first. They must then pass a series of verified, unannounced follow-up tests. Only then can they resume safety-sensitive work. These tests can continue for up to five years after a positive result.

Across both airlines, 23 employees returned to safety-sensitive positions without completing this process. That points to real gaps in how each carrier managed its aviation substance testing compliance obligations.

The scale of the sector adds context. The FAA oversees hundreds of carriers and more than 700,000 people in safety-sensitive aviation roles across the United States, according to US Department of Transportation data. The lapses at American and Southwest were not isolated slip-ups. They spanned years.

What Happens Next

Both carriers have 30 days to respond to the proposed fines. They can contest the amounts, negotiate a settlement, or accept the charges. Airlines commonly settle with regulators for a reduced sum in exchange for agreeing to stronger compliance measures.

The scrutiny lands at a difficult moment for US aviation. The sector has faced sustained public and political attention over safety standards following a series of high-profile incidents over the past two years.

The expectation from passengers is simple. Every crew member and every engineer who touches an aircraft should be fit to do their job. Rigorous airline drug and alcohol testing, consistently applied and properly followed up, is central to that promise.
