Southwest Airlines Co. v. Saxon
The Supreme Court ruled unanimously that airline cargo loaders — including ramp supervisors who regularly load and unload planes — are exempt from the federal law that otherwise forces workers to arbitrate disputes individually, because they are directly engaged in interstate commerce.
The decision lets workers like the ramp supervisor at the center of the case pursue their wage claims in court as a class rather than in private arbitration, and clarifies which transportation workers fall outside the Federal Arbitration Act's reach.
How it got here: A federal district court held Saxon was not exempt; the Seventh Circuit reversed; the Supreme Court agreed to hear the case to resolve a conflict with the Fifth Circuit.
The Case in Depth
What happened
Latrice Saxon works as a ramp supervisor for Southwest Airlines at Chicago Midway Airport. Her job regularly requires her to personally load and unload baggage, mail, and freight on and off planes flying across the country, in addition to training and supervising ramp agents who do the same work. Believing Southwest was underpaying overtime wages, she wanted to sue on behalf of herself and fellow ramp supervisors. Southwest tried to enforce a contract clause requiring her to resolve any dispute through individual arbitration rather than a class-action lawsuit.
The question before the Court
Can an airline ramp supervisor who regularly loads and unloads cargo on planes avoid a mandatory one-on-one arbitration agreement because she belongs to a class of workers "engaged in interstate commerce"?
The Court's answer
Yes — Saxon qualifies as a member of a "class of workers engaged in foreign or interstate commerce," which means she is exempt from the Federal Arbitration Act and cannot be forced into individual arbitration.
The Court reached this in two steps. First, it defined Saxon's "class of workers" by what she actually does — frequently loading and unloading cargo on planes — not by what her employer does as a whole. Second, it held that workers who physically load cargo onto planes traveling in interstate commerce are directly "engaged in" that commerce. Plain statutory text, reinforced by the Court's earlier decisions and by the FAA's own definition of related terms, left no serious doubt.

Why it matters
Transportation workers who regularly handle cargo crossing state lines may now be able to sue their employers in court instead of being forced into one-on-one arbitration. This matters most in wage-and-hour disputes, where class actions typically recover far more than individual arbitration. Cargo handlers, freight loaders, and similar workers at airlines — and potentially other carriers — could benefit directly.
What changes now
Saxon's overtime wage class action against Southwest under the Fair Labor Standards Act can now continue in federal court rather than being diverted to individual arbitration. The ruling also provides guidance for other airline cargo workers in similar roles. The Court explicitly left open whether ramp supervisors who only supervise cargo loading — and never physically handle cargo themselves — would also be exempt, leaving that question for future cases.
What this does not decide
The Court did not decide whether supervisors who only oversee cargo loading, but never personally handle cargo, are also exempt from the FAA. It also did not resolve ongoing lower-court disagreements about workers in other industries — such as "last mile" delivery drivers or food delivery workers — whose ties to interstate commerce are more indirect.
How the Court got there
The legal reasoning, step by step
- The Court first had to define Saxon's 'class of workers' under FAA §1. It rejected the idea that all airline employees form one class simply because airlines operate in interstate commerce. The statute says 'workers' — not 'employees' — which focuses attention on the work actually performed. The word 'engaged' similarly emphasizes what members of the class typically do day-to-day. Saxon's class is therefore workers who physically load and unload cargo on planes, not all airline employees.
- Next the Court asked whether cargo loaders are 'engaged in foreign or interstate commerce.' The ordinary 1925 meaning of 'commerce' includes the transportation of goods across state lines. Workers who physically load and unload cargo onto planes flying interstate are, the Court said, directly involved in that transportation — a conclusion it called 'too plain to require discussion,' citing a 1924 railroad loading case (Baltimore & Ohio Southwestern R. Co. v. Burtch) that treated loading and unloading as part of interstate transit.
- The Court drew further support from Circuit City Stores, Inc. v. Adams (2001), which had used two canons of statutory interpretation — the rule that different words in a statute carry different meanings, and the rule that a catchall phrase at the end of a list takes its meaning from the specific items before it — to conclude that §1 exempts only 'transportation workers.' Circuit City also said any exempt worker must play a direct and necessary role in the flow of goods across borders. Cargo loaders meet that standard.
- A final textual clue came from FAA §1's own definition of 'maritime transactions,' which lists 'wharfage' (payments for access to a cargo-loading dock) as a 'matter in foreign commerce.' The Court reasoned that if paying to access a loading facility counts as commerce, then actually loading cargo at such a facility is even more squarely 'engaged in' commerce.
- The Court rejected Southwest's narrower reading that only workers who physically ride aboard vehicles crossing state lines — pilots, ship crews, and the like — qualify. Southwest tried to use the fact that 'seamen' must be employed 'on board a vessel' to narrow the catchall provision in the same way. But Southwest itself admitted that 'railroad employees' is ambiguous on this point, which the Court said defeated the argument: a catchall phrase cannot be narrowed based on an attribute found in only one of the specific items preceding it.
- The Court also turned aside Southwest's argument that the FAA's general pro-arbitration purpose should push toward fewer exemptions. The Court acknowledged using statutory purpose to interpret the FAA before, but said it is not free to override clear statutory text in the name of advancing a policy goal — and here the plain text was clear enough on its own.
Doctrinal impact
Cases affected by this decision
Reaffirms Circuit City Stores, Inc. v. Adams (532 U. S. 105)
The transportation-worker framework and canons Circuit City used still govern who is exempt from the FAA.
Reaffirms Baltimore & Ohio Southwestern R. Co. v. Burtch (263 U. S. 540)
Loading and unloading interstate shipments remains part of interstate transportation, not a separate activity.
Distinguishes Gulf Oil Corp. v. Copp Paving Co. (419 U. S. 186)
That case involved activities far more removed from interstate commerce than physically loading cargo onto outbound planes.
