Did two recent summers for Servisair as a Dispatcher / Load Controller/ Turnaround Co-ordinator.....Call it what you will
First season I was on a casual contract zero hours...so varied from 45+ hours a week in the peak of the summer to 10 right at the end of October wage was £6.44 for everything no extras at all.
Second season only difference was that I got a part-time temporary contract of 20 hours....helped a bit towards the end of summer when the hours where dropping off!
Certainly wouldn't go back for the money .....but a very fun exciting first step on the ladder job if you are wanting to get into aviation and I have fond memories of it!
Advice would be try to get into a big airline who self-handle ......most of the handling agents treatment of lower level staff has deteriorated severely in recent years considering the amount of responsibility held.
