Try this
- Identify the travel stages where a message might be possible, and distinguish possibilities from commitments.
- Agree on a simple arrival update if wanted. Handle genuine emergency planning separately through appropriate contacts and services.
A worked example
“I may have no connection between trains. I’ll message after I reach the hotel, rather than trying to update from every station.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
If the itinerary changes, send an update when practical. Avoid escalating ordinary connection gaps into repeated demands for location proof.
