I need to check if I can bring the items I am planning on bringing. Who should I ask? The airport or the airline I'm flying with?

Additional info :

  • Airport - Perth Airport T1
  • Airlines - Cathay Pacific
  • Items I'm not sure if I could bring - Toothpaste, mouthwash, Vegemite, chocolate

I'm listing these details for additional info, but my question still remains as a generic one. I'm not specifically asking if I could bring the above items on said airport and airline, I'm asking for who I should contact so I can confirm with them.

Short answer: To be sure both, and check with the customs of the place you're flying to if it's an international flight.

The airport security will have it's own rules, probably based on national or international standards. The airline will also follow those rules but may impose additional rules or requirements. Finally the country you are flying to may have rules regarding import and declaration of different things.

The airline will likely know the local airport rules, but they may not have completely up to date information. The airport staff will not necessarily know about specific airline rules. And neither of them will care if you're going to get your Vegemite confiscated when they land, because all they care about is the safety of the airport, aircraft and getting you to the destination (and through immigration there).

Fortunately you don't specifically need to contact anyone as all this information is generally on the internet. If you're carrying something unusual then you need to check, and it can't hurt to check over the phone just in case the rules have changed.

For examples, here's Cathay Pacific's Prohibited Items list you'll want to cross-check the Liquids / Gels / Aerosols restrictions page too. And here's Perth Airport page covering both. Finally here's the generic Australia page on the same topic.

For your list, Toothpaste, Mouthwash and (probably) Vegemite are all going to count as 'Liquids, aerosols or gels' therefore (from my last link):

  • Liquid, aerosol or gel products (such as toiletries) must be in containers of 100 millilitres or less (broadly equivalent to 100 grams or less).
  • The containers must be carried in one transparent, resealable plastic bag, like the one in the image below.
  • The four sides of the bag's sealed area must add up to no more than 80 centimetres (e.g. 20x20 cm or 15x25 cm).

There's more on the page, but that's the basics. One bag, resealable, matching those sizes, each individual thing in containers of 100ml of less. That's for cabin baggage, all of those should be fine in checked baggage if you have bigger sizes.

Chocolate should be fine in carry-on or checked bagged as long as it's a reasonable amount, I guess there might be a country somewhere that controls the import of chocolate but I can't find one.

I'm guessing your flight is domestic, but for completeness here's the Australian Customs page on Food, Plants and Animals which may apply.

  • Otherwise spot on, but a Cathay Pacific flight from Perth is highly unlikely to be domestic ;) Commented May 28, 2015 at 6:03
  • @jpatokal D'oh -- you have a point there. :)

    Don't forget the local law enforcement authorities. US airlines generally allow transportation of firearms in checked baggage, but New York law requires permits for the possession of firearms. People have been arrested.

  • If your flight has scales, I would recommend checking also with those airports. If you miss a connection you might have to spend the night and have to cross the security control there. Commented May 28, 2015 at 23:01

At the end of the day, the airline. Airline get full control over what goes into the plane's cabin and hold, so they should be your first point of contact. They will also generally be aware of the airport (or, rather, government) restrictions of the day.

However, since airport security is run by the government, they've also got their own rules that you need to comply with. The airport itself is not directly involved though, and for anything mildly borderline they'll just tell you to go call the relevant government agency, which in Australia is the Department of Infrastructure.

Your specific items, though, are easy enough to figure out, and these answers will apply to 99% of airlines and airports:

  • But to get to the airplane, you have to pass through the airport, which may have tighter restrictions. For example, the airline might allow firearms in checked baggage, but there could be a city ordinance forbidding the possession of firearms.
