Worked for Aviance in London for more than 2 years, and my girlfriend works for them at the moment. I cannot say anything about outstations. YouŽll find the problems youŽd find in any other handling agent or airline (admin problems, rosters, etc), but the unions are quite strong and, to be fair, Aviance, at least on a local basis, tries to keep the staff happy. The money was good (that is, for the job I was doing), almost the best wages for the same position in LHR.
Staff benefits, the usual. Pension scheme, some travel discount and good prospects of promotion and movement between departments.
