Essential checklist for an international flight

Passport, visas and electronic authorizations

The first check concerns passport remaining validity: many countries, including Argentina, Australia, Egypt, India and Thailand, require at least six months beyond your return date, while the United States only asks for a document still valid. Checking the specific rule of your destination (here's how to understand if your passport is enough) avoids unpleasant surprises at check-in. Similarly, a visa or electronic authorization like ESTA for the United States or equivalent systems from other countries must be obtained with the necessary lead time, which can be several weeks.

Currency, customs and travel insurance

Organizing in advance a minimum amount of local currency and adapters for electrical outlets avoids complications in the first hours after arrival. The customs declarations required by the arrival country must be checked before departure if you're traveling with valuable goods or large quantities of cash, as well as the coverage of your health insurance abroad, often missing from policies designed only for your own country.

Practical details not to overlook

Learning about the main regulatory or cultural differences of your destination, from limits on importing certain products to dress codes in certain places, completes the specific preparation for an international flight.

The most useful tip for an international flight: check the passport validity rule required by your specific destination, because it's not always six months and varies from country to country.
