I did have a giggle the other day when standing next in line at the x-ray- waiting for the passenger in front of me to go through the metal detector- only to have two Jetstar pilots put their stuff in front of mine for the X-ray, say 'excuse me', walk through the metal detector, pick up their stuff and then toddle off to the coffee shop. Their was two people behind me.
To both QF crew and JQ crew, if you're going to push to the front of the security line, don't then walk into the coffee shop and sit down for the next 20 minutes. Passengers notice that stuff.
