Overview
- American launched the feature in its mobile app at the end of September and early October 2026, with the change appearing in App Store notes for version 2026.28.
- Solo AAdvantage members with an assigned seat can opt in after booking and choose a window, aisle or middle preference for automatic monitoring and reassignment.
- Moves are limited to the passenger’s ticketed cabin, carry no extra charge, will not place customers into higher‑priced seats, and exclude exit rows and multi‑passenger reservations.
- When multiple customers seek the same seat type, the system gives priority first to AAdvantage status and then to the order in which members enrolled for the service.
- American says the tool was built through its two‑year ADEPT program using early‑career technologists and AI‑enabled development tools, and the rollout follows a broader airline trend of adding automated services to apps.
