What passport validity is required for international flights?

Most foreign countries require your passport to be valid for at least 6 months beyond your scheduled departure date, along with 2-4 blank visa pages.

Can I take prescription medication on international flights?

Yes. Always carry medications in their original pharmacy-labeled containers inside carry-on baggage. Bring a written doctor's prescription or letter explaining your medical condition, especially for controlled substances.

Are liquid rules the same at international airport security?

Yes. Almost all international aviation security authorities (CATSA, ECAC, JCAB, CASA) enforce the standard 100ml (3.4 oz) limit per container, sealed in a single 1-quart transparent bag.

How much cash can I carry on an international flight without declaring?

You can carry up to $10,000 USD (or foreign currency equivalent) without declaring. Amounts equal to or exceeding $10,000 must be reported on customs forms upon arrival or departure.

Can I bring duty-free liquids bought at airport shops onto connecting flights?

Duty-free liquids exceeding 100ml are allowed ONLY if sealed in a Secure Tamper-Evident Bag (STEB) with the original purchase receipt visible inside. If re-clearing security in another country, they may be re-inspected.

What food items are banned at international border customs?

Most countries strictly prohibit fresh fruits, vegetables, seeds, plants, unprocessed meats, and dairy products to prevent agricultural pest infestation.

What should I do if my checked bag is lost internationally?

Report lost luggage immediately at your arriving airline's baggage service desk before exiting customs. Fill out a Property Irregularity Report (PIR) and retain your baggage claim check tags.

Do I need a power converter or just a plug adapter for overseas travel?

Most modern smartphones, laptops, and camera chargers are dual-voltage (100V-240V) and only require a plug adapter. High-wattage hair dryers or straighteners may require a voltage transformer.
