DELTA AIR LINES, INC. · 2026-07-10 · Importance 40 · Surprise 42 · In source text
Delta TechOps third-party MRO revenue increased versus the prior period driven by a shift in work mix toward legacy engines versus next-generation engines. Management expects this mix shift to continue through 2026, supporting higher third‑party MRO revenues. The MRO business contributed to the growth in other revenue alongside cargo and refinery sales, indicating demand from external airline and operator customers. This shift affects TechOps workload composition and may influence margins depending on parts and labor intensity of legacy engine maintenance.
