Do the important checks the evening before departure, not while transport is waiting. Put identification, tickets, booking details, medicine, keys, and payment methods together in a secure place.
Prepare the home for the length of the trip. Lock doors and windows, handle food and rubbish, unplug appropriate devices, adjust heating or cooling, and arrange care for plants, pets, or deliveries.
Just before leaving, check the route and current travel updates, charge the phone, download essential information, and share the plan with a trusted person when appropriate. Pause at the door for one final essentials check.
