Flight chains fail in the last hour, not in the booking email.
Humans already know this story — Kanpur to Lucknow when the buffer vanished. Agents face the same street.
What the agent must do
1. Read the itinerary window (planner agent). 2. Book a real hop on 19Cabs with OTP (booking agent). 3. If confirmation is slow, raise fare within limits — criticality on the screen. 4. Hand `liveTrackUrl` to the next agent or to the traveler.
Why not “just notify the user”
Notifications do not move metal. 19Cabs is the network that moves it. Same captains as the app. Same fare control idea.
