Appeal from the United States District Court for the Southern District of Texas USDC No. 4:21-CV-3451 ______________________________

ON PETITION FOR REHEARING EN BANC

Before Graves, Engelhardt, and Oldham, Circuit Judges. James E. Graves, Jr., Circuit Judge: Treating the petition for rehearing en banc as a petition for panel rehearing (5th Cir. R. 35 I.O.P.), the petition for panel rehearing is DENIED. Because no member of the panel or judge in regular active service requested that the court be polled on rehearing en banc (Fed. R. App. P. 35 and 5th Cir. R. 35), the petition for rehearing en banc is DENIED. The opinion issued June 4, 2025 is withdrawn by the panel and the following is substituted in its place.

No. 24-20136

Appellant Anna Palova claims that United Airlines (“United”) unlawfully terminated her on the basis of her age, in violation of the federal Age Discrimination in Employment Act (“ADEA”) and the Texas Commission on Human Rights Act (“TCHRA”). United contends that Palova violated her collective bargaining agreement by manipulating flight assignments to benefit her and her colleagues. The district court concluded that the Railway Labor Act (“RLA”), which divests federal courts of jurisdiction over certain employer-employee disputes, applied to Palova’s claims, and granted summary judgment in United’s favor. Because the Railway Labor Act does not preclude or preempt 1 Palova’s age discrimination claims from being heard in a federal forum, we VACATE the district court’s order and REMAND for further proceedings consistent with this opinion. I. Anna Palova worked as a Houston-based flight attendant for United from 1992 until February 2020. 2 She maintained “a perfect attendance and performance record” over this near thirty-year career. Despite this, United terminated Palova upon determining that she committed infractions linked to “parking,” a scheduling tactic related to the flight attendant industry. Parking results from the fact that an airline uses a scheduling system to efficiently distribute attendants across all of its flight offerings. United accomplishes this by assigning a group of flights, known as a “line,” to attendants based on seniority. After lines are distributed, attendants are allowed to trade with each other and/or forfeit unwanted trips into an open _____________________ 1 The RLA, if applicable, has a preclusive effect on federal claims and a preemptive effect on state law claims. See generally Hawaiian Airlines v. Norris, 512 U.S. 246, 259 n.6 (1994) (describing “RLA preclusion of a cause of action arising out of a federal statute” and “RLA pre-emption of a cause of action arising out of state law”). 2 Continental Airlines, Palova’s original employer, merged with United in 2010.

pool for others to take. Parking occurs when an attendant places a flight onto another attendant’s schedule to facilitate that flight’s eventual transfer. Attendants who possess a parked flight—that is, one they have no intent of servicing—often receive some kind of compensation in exchange for a desirable slot. The joint collective bargaining agreement (“JCBA”) that governs United flight attendants’ labor relations forbids parking. On March 22, 2019, a United executive issued an “Inflight Leadership Update” reminding all flight attendants that the airline had “zero tolerance” for parking and would “fully investigate [any instances] and take appropriate action, up to and including discharge.” The following day, March 23, the executive officers of United’s flight attendant union issued a letter stating that “management has been left with no alternative but to investigate these [parking] concerns.” The airline’s Corporate Security Department then “developed an algorithm to analyze flight trading data and determine [which flight attendants] had engaged in problematic trades.” According to United, this algorithm identified 28 flight attendants across three hubs. Palova was one of the 28. On February 17, 2020, Palova received a letter directing her to attend an investigatory meeting scheduled for February 20. United found Palova’s explanations unconvincing, and concluded she engaged in parking in violation of the JCBA. She was terminated on February 28, 2020. Palova has a different explanation for her firing. She theorizes that her old age made her an optimal target for termination as United cut costs to offset COVID-related profit losses. Palova also alleges that the only three Houston-based attendants fired for parking were “all women in their late fifties or early sixties who had worked at the airline for decades.” And Palova avers that United’s investigation was a sham: she notes that the airline’s algorithm gave substantial weight to an attendant’s seniority, and asserts that

the key piece of evidence used against her—a spreadsheet that detailed her alleged parking maneuvers—was “illegible and in small print” and presented to her “less than an hour” before the interview. Palova sued United in the Southern District of Texas on October 20, 2021. She originally alleged three claims: age discrimination in violation of the ADEA, age discrimination in violation of the TCHRA, and breach of contract. She later filed an Amended Complaint that contained only the ADEA and TCHRA claims—though in her facts section, Palova maintained that she had not parked at all. After discovery, United moved for summary judgment on two grounds: (1) the Railway Labor Act (“RLA”) precluded Palova’s ADEA claim and preempted her TCHRA claim, and (2) her discrimination claims were unsupported by the evidentiary record. On March 5, 2024, the district court granted United’s motion, finding that summary judgment was warranted due to the RLA’s preemptive and preclusive effect. It specifically reasoned that, under the McDonnell-Douglas burden-shifting standard, the burden would shift to United to provide a “legitimate, nondiscriminatory reason for [her] termination,” and United would “undoubtably rely on the JCBA as its legitimate, nondiscriminatory reason for [Palova’s] termination.” This position would require the district court to “determine if Plaintiff actually engaged in Parking, which is not within the Court’s jurisdiction to do.” Palova timely appealed. II. The district court’s order, a complete grant of summary judgment in United’s favor, creates finality under 28 U.S.C. § 1291. The core of this appeal—whether the RLA precludes or preempts Palova’s allegations— resolves subject-matter jurisdiction, as the RLA “divests federal courts of jurisdiction over minor disputes” between carriers and employees.
