I used to work as an aircraft cleaner (or as some people like to call it, aircraft groomer) at MAN
and in that time i cleaned :
I can't remember if i also cleaned Monarch or the then titled Air 2000.
I'll never forget almost being knocked off my feet when i was cleaning one of Virgins 747's, i was reaching for a seat pocket to check it and the tug driver began towing the aircraft onto the stand. I ended up 'headbutting' the seat!!
One day i was in the cockpit of a Delta MD
-11, and there were THREE flightcrew in there. So as i'm vacuuming in there, the 3rd flightcrew member is sitting there eating crackers spilling most of it on himself and the floor!!!!!!
I got the job by checking the airports website, plus in the UK we have 'jobcentres' where lots of jobs are posted so that always helped when i was searching for a job at the airport.
