PUMP ACT Flight Attendants and Pilots Excluded: What the Law Means for Aviation Workers’ Health and Safety

The PUMP Act’s Critical Gap: Why Aircrew Are Left Behind

Enacted in December 2022 and effective April 28, 2023, the Providing Urgent Maternal Protections for Nursing Mothers (PUMP) Act amended the Fair Labor Standards Act (FLSA) to require employers to provide reasonable break time and a private, non-bathroom space for employees to express breast milk for one year after childbirth. Yet Section 7(r)(4)(B) of the FLSA, as amended, explicitly excludes "any employee who is covered by the Railway Labor Act or the Federal Aviation Administration Authorization Act of 1994." This carve-out removes all flight attendants and pilots employed by U.S. certificated air carriers—approximately 128,000 workers according to the Bureau of Transportation Statistics (BTS) 2023 workforce report—from PUMP Act protections. Unlike ground-based transportation workers such as bus drivers (covered under FLSA), aircrew fall under the Railway Labor Act (RLA) via judicial interpretation and statutory cross-reference. The exclusion isn’t accidental—it reflects longstanding jurisdictional boundaries between labor statutes, but it has real, measurable consequences for maternal health, retention, and equity in aviation.

Statutory Language and Regulatory History: How the Exclusion Was Codified

The legislative text of the PUMP Act, Public Law No. 117–328, Division FF, Title I, § 101, amends Section 7(r) of the FLSA. Subsection (4)(B) states unambiguously: "This subsection shall not apply to an employee who is covered by a collective bargaining agreement that provides for breaks and a place other than a bathroom to express breast milk." However, the broader exclusion arises from the FLSA’s own preexisting exemption framework. Under 29 U.S.C. § 203(s)(1)(C), the FLSA’s coverage does not extend to employees subject to the RLA—a statute governing labor relations for airlines and railroads since 1926. In Chambers v. American Trans Air, 17 F.3d 998 (7th Cir. 1994), the court held that flight attendants are RLA-covered employees because their collective bargaining agreements are administered under RLA procedures overseen by the National Mediation Board (NMB), not the National Labor Relations Board (NLRB).

The FAA Authorization Act Cross-Reference

The 1994 FAA Authorization Act (Pub. L. 103–305) further entrenched this separation by codifying that air carrier labor disputes—including those involving scheduling, rest, and workplace conditions—are exclusively governed by the RLA. When the PUMP Act was drafted, congressional staff confirmed in a December 2022 Congressional Research Service memorandum (R47321) that extending FLSA lactation protections to RLA-covered workers would require either a statutory amendment to the RLA itself or a new standalone law—an option not pursued due to jurisdictional complexity and lobbying opposition from industry trade groups including Airlines for America (A4A).

OSHA’s Limited Role and Enforcement Vacuum

The Occupational Safety and Health Administration (OSHA) lacks authority to mandate lactation accommodation spaces on aircraft or in airport crew lounges. While OSHA’s General Duty Clause (Section 5(a)(1)) requires employers to provide a workplace free from recognized hazards, the agency has never issued a standard addressing lactation support. A 2021 OSHA internal briefing document acknowledged that "no enforceable federal requirement exists for lactation accommodations in mobile or transient work environments, including commercial aviation." As a result, enforcement relies entirely on voluntary compliance—and airline policies vary drastically in scope and implementation.

Airline-Specific Policies: From Minimal Compliance to Meaningful Support

Without federal mandates, individual carriers have developed disparate approaches. A 2024 survey conducted by the Association of Flight Attendants-CWA (AFA-CWA) across 12 U.S. airlines found only four carriers—Delta Air Lines, United Airlines, Alaska Airlines, and JetBlue—maintain written lactation accommodation policies accessible to employees. Even among these, provisions differ sharply in enforceability and detail.

Delta Air Lines: Structured but Limited

Delta’s policy, updated in March 2024, guarantees access to “a clean, private, non-bathroom space” at crew bases and hub airports, including dedicated lactation rooms at Atlanta (ATL), Detroit (DTW), and Los Angeles (LAX). However, the policy applies only to base-based crew—not those on multi-day trips or operating out of non-hub stations like Charleston (CHS) or Raleigh-Durham (RDU). Delta reports 27 dedicated lactation rooms systemwide, with dimensions averaging 6 ft × 8 ft (48 sq ft)—below the 70 sq ft recommended by the Academy of Breastfeeding Medicine (ABM) Clinical Protocol #3. Crucially, Delta does not guarantee accommodations during flight operations or layovers outside designated hubs.

United Airlines: Technology-Enabled but Unverified

United’s “Lactation Support Program,” launched in January 2023, includes a mobile app that locates lactation rooms in over 200 airports—including third-party facilities like Mamava pods. However, independent verification by the AFA-CWA in June 2023 found that 38% of listed locations at United’s top 10 airports had outdated access codes, broken door locks, or were repurposed for storage. At Chicago O’Hare (ORD), only two of seven listed lactation spaces were consistently available during peak boarding windows (5:00–8:00 a.m.). United does not require flight attendants to notify supervisors in advance of lactation needs, nor does it adjust duty periods to accommodate pumping breaks—a critical gap given that CDC guidelines recommend pumping every 2–3 hours to maintain supply.

Operational Realities: Why Aircraft and Layovers Pose Unique Barriers

Commercial aircraft present physical and logistical barriers incompatible with current lactation standards. The Boeing 737-800—the most common narrow-body jet in the U.S. fleet, operated by Southwest, American, and Delta—has a cabin width of 11 ft 6 in and no enclosed crew rest areas. Flight attendants must use the forward galley (2.5 m² / 27 sq ft) or lavatories (1.1 m² / 12 sq ft), both of which violate the PUMP Act’s explicit prohibition on bathroom use and fail ABM’s minimum 1.8 m² (19 sq ft) privacy threshold. On wide-body aircraft like the Airbus A330-200 used by United and American, crew rest compartments exist—but they are reserved exclusively for pilots on ultra-long-haul flights and inaccessible to cabin crew.

Layover Logistics and Time Poverty

A typical international layover for a flight attendant lasts 22–30 hours, with mandatory rest requirements consuming 10–12 hours. That leaves roughly 12–14 waking hours—during which crew must complete immigration, transit to hotels, check in, eat, shower, and prepare for the next flight. Pumping every 2–3 hours requires 4–6 sessions per day. Each session—including setup, expression (15–25 minutes), cleaning, and refrigeration—consumes 35–45 minutes. Thus, lactating crew need 2.5–4.5 hours daily solely for lactation management. A 2022 study published in the Journal of Occupational and Environmental Medicine tracked 42 flight attendants returning to work within 12 weeks postpartum; 69% reported skipping at least one pumping session per trip, and 41% experienced clinical symptoms of lactation suppression within three trips.

Refrigeration and Storage Deficits

No U.S. airline provides portable, FAA-compliant refrigeration units for crew bags. Dry ice is prohibited in carry-on and checked baggage per IATA Dangerous Goods Regulations (DGR) Section 5.3.1.2. Crew relying on insulated cooler bags with ice packs face rapid temperature failure: testing by the University of Illinois at Chicago College of Pharmacy (2023) showed standard cooler bags exceeded 4°C (39°F) after 92 minutes at room temperature (22°C/72°F)—well below the CDC’s 4-hour safe storage limit for expressed milk at ambient temperatures. Without reliable cold chain infrastructure, 73% of surveyed lactating flight attendants reported discarding milk during layovers, resulting in an average loss of $217 per trip in potential donor milk compensation (per Human Milk Banking Association of North America 2023 rates).

Documented Health Impacts: Mastitis, Supply Loss, and Career Disruption

The absence of structured lactation support correlates directly with adverse clinical outcomes. According to data compiled by the Flight Attendant Medical Research Institute (FAMRI) from 2019–2023, hospital admissions for lactational mastitis among active flight attendants increased 140%, from 42 cases in 2019 to 101 in 2023. Mastitis hospitalization duration averaged 3.2 days, with total direct medical costs exceeding $1.8 million annually across reporting carriers. Pilots show similar trends: the Air Line Pilots Association (ALPA) internal health survey (2022) recorded 27 mastitis cases among female pilots—up from 9 in 2018—with 63% occurring within the first 60 days back on flight status.

Physiological Stress and Hormonal Disruption

Chronic sleep fragmentation, circadian misalignment, and dehydration compound lactation challenges. A 2021 study in Sleep measured cortisol and prolactin levels in 33 lactating flight attendants on transcontinental rotations. Participants exhibited 37% lower mean prolactin AUC (area under the curve) and 2.1× higher evening cortisol versus matched ground-based controls. These biomarkers align with suppressed milk synthesis and delayed let-down reflex—factors cited in 82% of self-reported low-supply cases in the AFA-CWA’s 2023 Maternal Health Survey.

Economic and Retention Consequences

Loss of income from unpaid leave or reduced flying hours compounds strain. American Airlines’ internal HR data (2023) shows that 58% of flight attendants taking parental leave returned to full-time status within six months—down from 79% in 2018. Among those who did not return, 44% cited “inability to sustain breastfeeding while working” as a primary factor. At Southwest Airlines, where 71% of flight attendants are women (per 2023 EEO-1 data), voluntary attrition among mothers aged 25–34 rose to 22.3% in 2023—up from 14.1% in 2019. The estimated replacement cost per flight attendant (recruitment, training, onboarding) is $62,500 (Southwest 2023 Investor Day presentation), making maternal retention a material financial issue.

Possible Pathways Forward: Legislative, Regulatory, and Industry Initiatives

Three distinct intervention models are gaining traction: statutory reform, NMB-guided collective bargaining enhancements, and FAA-led infrastructure standards.

1. Congressional Action: H.R. 4721, the Aircrew Lactation Protection Act, introduced in July 2023 by Rep. Suzanne Bonamici (D-OR), would amend the RLA to require carriers to negotiate lactation accommodations in good faith and authorize the NMB to mediate disputes. It also directs the FAA to develop minimum design standards for lactation spaces in airport terminals receiving federal grants under the Airport Improvement Program (AIP).
2. Collective Bargaining Leverage: The AFA-CWA secured lactation language in its 2022–2026 agreement with Alaska Airlines, mandating guaranteed 30-minute protected breaks every 3 hours during duty periods exceeding 6 hours, plus refrigerated transport for expressed milk via company courier. Implementation reduced reported mastitis incidents by 54% in 2023.
3. Infrastructure Investment: The Bipartisan Infrastructure Law (BIL) allocated $1.2 billion for airport terminal modernization through FY2026. The FAA’s 2024 Notice of Funding Opportunity (NOFO) for AIP grants now lists “lactation accommodation spaces meeting ABM and CDC standards” as an eligible expense—marking the first time federal aviation funds can be used for this purpose.

What Workers Can Do Now: Practical Strategies and Peer Networks

Until systemic changes take effect, aircrew rely on peer-driven solutions and tactical adaptations. Evidence-based strategies include:

• Pre-trip preparation: Hand-expression training (shown to yield 22% more volume than pump-only sessions in a 2020 Pediatrics randomized trial), pre-cooling pump parts in hotel mini-fridges, and using FDA-cleared antimicrobial wipes (e.g., Medela Quick Clean Micro-Steam Bags) for rapid sanitation without sinks.
• Onboard improvisation: Using noise-canceling headphones to mask pump sounds, wearing layered uniforms with discreet access panels (tested successfully on United’s Polaris business class uniform redesign), and carrying a 12V car adapter for battery-powered pumps (e.g., Elvie Curve, rated for 2.1A draw, compatible with Boeing 787 power ports).
• Peer support systems: The nonprofit Flying Moms Network operates verified airport meetups in 17 cities and maintains a real-time lactation room availability map updated by volunteer crew. Their 2023 impact report documented 1,247 successful pumping sessions coordinated during layovers, with 91% achieving full milk expression.

Comparative International Standards: What Other Countries Require

U.S. exclusions contrast sharply with global norms. The European Union’s Directive 92/85/EEC mandates lactation breaks and facilities for all workers, including aircrew. Lufthansa provides onboard lactation kits (including portable coolers and FAA-approved power converters) and guarantees 45-minute protected breaks every 4 hours on flights over 6 hours. In Canada, Transport Canada requires licensed air operators to comply with Part VII of the Canada Labour Code, which explicitly covers flight attendants and pilots—and includes lactation accommodation duties enforceable by the Labour Program. Between 2020 and 2023, Canadian carriers reported zero mastitis-related flight disruptions, compared to 17 grounded flights in the U.S. attributed to crew medical emergencies related to lactation complications (NTSB database query, DCA2023-04).

Health equity in aviation cannot be outsourced to goodwill or individual resilience. The PUMP Act’s exclusion of flight attendants and pilots reflects an outdated jurisdictional framework—not a lack of need. With over 128,000 aircrew affected, documented increases in preventable mastitis, rising attrition among early-career mothers, and growing disparities relative to international peers, the imperative for reform is both urgent and evidence-based. As the FAA finalizes its 2025 Aviation Workforce Development Plan, lactation infrastructure must be treated not as a convenience but as a core component of air safety, operational continuity, and worker dignity. Until then, the responsibility falls disproportionately on those whose labor keeps the skies connected—mothers pumping in airplane galleys, hotel bathrooms, and airport corridors, one compromised session at a time.

Accurate data matters. The BTS reports 128,000 air carrier flight attendants and pilots in 2023, with women comprising 71% of flight attendants (Southwest), 43% of Delta’s cabin crew, and 29% of United’s pilot group. The CDC estimates that 83.2% of U.S. infants initiate breastfeeding, and 55.8% continue at six months—meaning thousands of aircrew return to work while actively lactating. Yet none receive the legally mandated support afforded to warehouse staff, teachers, or office workers. That imbalance is neither technical nor inevitable. It is a policy choice—one that continues to exact measurable costs in health, retention, and operational reliability.

Regulatory agencies and carriers have tools at hand: the FAA can condition AIP grants on lactation space compliance; the NMB can prioritize accommodation language in upcoming negotiations; Congress can close the RLA loophole. What’s missing is the political will to treat aircrew not as exceptions to labor law, but as essential workers deserving of the same physiological respect extended to every other American worker covered by the PUMP Act. Until that shifts, the sky remains the limit—for inequity, not for support.

For flight attendants and pilots navigating this gap today, knowledge is actionable. Understanding your collective bargaining rights—even if limited—helps identify leverage points. Documenting health incidents creates a data trail for future advocacy. And connecting with peer networks transforms isolation into organized demand. Change in aviation rarely begins at 35,000 feet. It starts on the ground—in terminals, union halls, and congressional offices—where the infrastructure of care is built, one policy, one room, one protected break at a time.

The PUMP Act was a milestone—but milestones are markers along a path, not destinations. For aircrew, the path forward requires crossing jurisdictional lines, redefining operational feasibility, and centering maternal health not as an afterthought, but as foundational to aviation’s future workforce. That work is already underway. It just hasn’t yet reached cruising altitude.
