Design a process for handling repeated seat disputes on a nearly full flight.

I would design the process so the first crew member handles the first minute the same way every time: verify the seat assignments, move the conversation out of the main aisle if possible, and separate facts from emotion quickly. Most seat disputes get worse because too many people start debating before anyone confirms the basics.

From there, I would split the cases into categories. If it is a simple misunderstanding, I would correct it and move on. If it is a request to swap, I would treat that as voluntary, not something the crew can force on another passenger. If it involves duplicate boarding data or an operational seating issue, I would escalate to the lead or gate team immediately.
