First, I can see where that could be very funny if done right. I can just see the bomb squad trying to disarm a vibrator.
Since this is a comedy bit, I wouldn't worry too much about being absolutely correct in every detail. If you want bomb sniffing dogs in the scene, add them. There used to be two or three types of airport guards; airport police, armed security guards, and the regular, unarmed guys. With all the Homeland Security stuff, that has changed somewhat.
If a suitcase was found that was suspected of having a bomb, they would overreact in the name of "playing it safe". They would close down the terminal, maybe the roads to the airport, maybe stop all planes from taking off, etc.
I'm no expert on airport security, just throwing out some ideas.
