According to an Italian newspaper (in Italian only, but throw it into babelfish.altavista.com and you’ll get the point), five people were so angry that their flight was oversold that they assaulted an Alitalia gate agent. And yes, one of them almost bit the poor agent’s ear off.
Apparently, there were many young people traveling together on the flight from Turin to Naples. The flight was oversold so five of them were put on another flight through Rome that landed only 15 minutes later. Now, that kind of treatment usually wouldn’t amount to much of a protest here in the US, but apparently in Italy it was an outrage.
The students started attacking and by the end of it, the agent had almost lost an ear. Ouch.
