List each destination and connection in order. For every stop, check what travel documents and entry or transit permission may be required for the traveller.
Compare passport expiry with the destination’s validity rules. Then read current travel advice and confirm anything uncertain with the relevant authorities.
Make the information usable
Keep a simple route note with booking references and contacts. If a connection or destination changes, redraw the list and check the affected rules again.
These are general editorial notes, not a decision about anyone’s eligibility to travel. Check current rules with the relevant authorities for your situation.
