They don't just hand out airside passes. Seem to remember having a 2 month wait for disclosure Scotland and criminal record checks prior to being given my pass to enable me to do my job. Conviction or failure to pass the disclosure = no pass = no job. If the pass did not give access to other airports, it would be a little difficult to operate return flights and I would do every return sector on the train!
Do 100% of passengers have to remove their shoes? Only asking as I know this didn't used to be the case, which was rather galling when the aircraft drivers did.
