I'm flying SYD/LAX and wondering f I an take (several) jars of Vegemite in my carry-on? I am flying Air NewZealand, didn't realise baggage allowance only included one checked bag. I don't want to pay for a second, but, the weight will be close to the limit. 2-3 lb's vege in my cary-on might help, but, it would be tragic if it was confiscated at security.
