Daniel Ferreras v. American Airlines Inc, 946 F.3d 178

American Airlines’ timekeeping system defaults pay to scheduled shift hours, automatically deducts a 30-minute meal break, and treats brief early/late clock-ins as unpaid “grace periods.”
Employees must request supervisor approval as an “exception” to be paid for pre-/post-shift, meal-break, or off-the-clock work; plaintiffs allege supervisors regularly deny such requests.
Putative class: all non-exempt, hourly employees at Newark Liberty International Airport from April 29, 2014 to present; named plaintiffs are fleet service employees and mechanics (no passenger-service agents among named plaintiffs).
District Court certified three subclasses (Grace Period, Meal Break, Off-the-Clock), finding common questions about the timekeeping system and a policy that discouraged exception requests; the court relied on “allegations and initial evidence” and compared to FLSA conditional-certification practice.
Third Circuit held the District Court applied the wrong Rule 23 standard (effectively conditional/pleading-level), failed to resolve key factual conflicts, and that commonality and predominance cannot be satisfied because individualized inquiries about whether members actually worked are necessary. The certification order was reversed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Proper Rule 23 standard for certification	Initial evidence / conditional approach is sufficient at this stage	Rule 23 requires a rigorous, preponderance-based analysis; no conditional certification	District Court applied improper pleading/conditional standard; must resolve disputes and require proof by preponderance
Commonality & Predominance (can class-wide proof resolve liability/amounts?)	Timekeeping system and alleged discouragement policy create common questions that can drive resolution	Whether each employee actually worked during disputed periods requires individualized proof; activities varied across employees	Commonality and predominance not met; individualized issues predominate; class cannot be certified
Use of representative/aggregate evidence (Tyson Foods analogy)	Representative proof can estimate unpaid time across the class	Tyson Foods is distinguishable because here employees’ activities while clocked in vary widely	Tyson Foods was distinguishable; representative evidence cannot resolve the individualized disputes here
Scope of class/subclasses across job categories	Single certification covers all non-exempt hourly employees at Newark	Different job groups (mechanics, fleet, passenger agents) have different duties/supervisors/policies; a putative company policy was shown primarily for mechanics	District Court’s class/subclass definitions overbroad given differing practices; classwide resolution not feasible
