Travel Practicalities
Travel Insurance
Most people's regular health insurance quietly stops covering them the moment they land in another country — travel insurance is what fills that specific gap.
Passports & Visas
A perfectly valid, unexpired passport can still get a traveler turned away at check-in — many countries require it to have several months of validity left beyond the trip itself.
Jet Lag
The same total number of hours flown can produce dramatically different jet lag depending on which direction the plane happens to be heading.
