Delta Faces Class Action Over Unpaid Military Leave for Pilots

Delta Air Lines is confronting a certified class action lawsuit from thousands of pilots who claim the carrier unlawfully denied them pay during short-term military service spanning nearly two decades. The litigation, which received class certification in August, encompasses approximately 3,361 pilots who collectively took 119,285 periods of short-term military leave between April 2007 and December 2022, with the final tally expected to grow substantially.

The crux of the dispute centers on Delta's policy of not compensating pilots for military leave lasting 30 consecutive days or fewer, even as the airline provides pay for jury duty, bereavement leave, and sick leave. Under the carrier's current framework, pilots on military assignment must either use accrued vacation time or go unpaid during their absence. While the Uniformed Services Employment and Reemployment Rights Act does not mandate paid military leave outright, it requires employers to extend the same benefits offered for comparable nonmilitary absences to service members.

The pilots' legal theory hinges on demonstrating that short-term military duty qualifies as comparable to at least one form of paid leave Delta already offers. Federal law evaluates comparability based on leave duration, purpose, and whether employees can choose when to take it. If an employer treats different but comparable leave types inconsistently, service members are entitled to the most favorable treatment provided for any such category. The plaintiffs argue they need only prove military leave resembles a single paid leave type — such as jury duty — rather than all of them.

Delta is expected to challenge the class structure by arguing that military absences vary too dramatically in nature to warrant uniform treatment. The airline will likely contend that a single-day National Guard drill differs fundamentally from a 30-day deployment in terms of length, purpose, frequency, and pilot control over timing. Some military obligations are mandatory while others are voluntary, and pilots retain the ability to trade shifts with colleagues. This defense strategy mirrors American Airlines' successful approach in defeating a similar class action last summer, where a judge determined military leave varied too widely for classwide resolution.

However, the Delta pilots counter that they are challenging a single, uniform company policy that applies the same unpaid-leave rule across all short-term military absences regardless of individual circumstances. Two separate lawsuits, filed on March 11 and March 16, 2021, have been consolidated into the current action. With potential damages reportedly exceeding $100 million, the case could establish significant precedent for how airlines compensate pilot-service members.
