I wanted to share a recent experience that may be useful for other frequent American Airlines travelers.
I was traveling from Europe to the United States on an itinerary that included a long-haul American Airlines flight from Frankfurt to Dallas. Months before departure, I selected an exit row aisle seat specifically for the extra legroom, a benefit I have regularly used as an Executive Platinum member for many years.
A week before departure and again during check-in, my seat assignment remained unchanged, and the exit row seat was even printed on my boarding pass. However, after an overnight stay in Frankfurt, I checked the app and discovered that I had been moved to a standard seat while my original exit row seat had been assigned to someone else.
When I spoke with customer service at the airport, staff reviewed the booking history and found no operational reason for the seat change. There had been no aircraft swap, and the passenger who received the seat was not traveling with companions who might have required seating adjustments.
According to the supervisor, the records suggested that the seat had been sold as a paid upgrade to another traveler, despite already being assigned to me. The situation was particularly surprising because my trip was already in progress and the seat reassignment occurred after check-in.
Fortunately, another exit row seat remained available, and later a last-minute upgrade to Business Class cleared. However, the experience raised concerns about whether premium seat assignments for elite members are being replaced by paid upgrade opportunities shortly before departure.
I am sharing this as a data point in case other travelers notice similar last-minute seat changes on future flights.
