bmi are recruiting customer service agents at GLA just now (if it has to be GLA or PIK). would most likely only be a 6 month contract @ 20 hours a week to begin with but with the summer season coming up theres usually overtime. as with most airlines, other departments vacancies (eg dispatch) are filled internally so you would need to start as a csa.
youd either be trained in EK's system and mainly do their flight to begin with or trained in bmi and bmibaby first, eventually leading to all 3 systems.
if youre interested then phone 0141 889 0660 and ask for an application.
dont work at PIK so dont know of anything there sorry
