Plaintiffs Christine Monahan, Lillian Taylor, and Renee Iannotti sued Southwest Airlines Company on behalf of themselves and all passengers who purchased tickets between August 2017 and March 2019. The plaintiffs alleged that Southwest breached its Contract of Carriage and Customer Service Commitment by flying unsafe Boeing 737 MAX aircraft with inadequately trained pilots.

The plaintiffs conceded they never flew on a MAX aircraft during the relevant period. Instead, they claimed Southwest overcharged them for tickets because the flights were not as safe as the airline promised. They argued that Southwest breached safety assurances regarding pilot training, aircraft safety, and FAA compliance.

The district court dismissed the complaint, concluding the plaintiffs failed to allege an injury in fact. The district court reasoned that because the plaintiffs did not fly on the MAX, they could not reasonably infer they were overcharged.

The Fifth Circuit affirmed the dismissal, holding that its prior decision in Earl v. Boeing Co. foreclosed the plaintiffs' theory of economic injury. The court determined that the plaintiffs' breach-of-contract claim was substantively identical to the fraud-based overcharge theory rejected in Earl.

The court noted that the plaintiffs' theory rested on the assumption that Southwest would have lowered ticket prices if the MAX's safety defects were known. The Fifth Circuit previously found this inference implausible, noting that the FAA likely would have grounded the aircraft, which would have raised ticket prices due to reduced capacity.

Because the plaintiffs could not plausibly allege they were financially worse off, they suffered no injury in fact. The court held that plaintiffs cannot recast an unpresented economic injury under a different legal theory to generate Article III standing.
