If your flight or train is late, enter your updated arrival date and time. TripPlanr keeps the original plan, then shows which reservations and timed activities are no longer reachable or have become tight.
- Activities marked Booked or Confirmed are protected from rescheduling.
- Flexible activities get conflict-aware replacement times you can review one at a time or apply in a safe batch.
- Move an affected activity back to Ideas, mark it handled, or undo the last recovery change.
- Warnings appear in Trip Details, Builder, and Itinerary.
