At EMA, Servisair are really the big cheeses when it comes to ground handling. They handle all the charter airlines (with the exception of TCX), including the ones who only fly in a few times a week, as well as FR & EZY. Their subsidiary Airport Agencies is responsible for the representation of all the major tour operators (again with the exception of Thomas Cook.) They're a great company to get some valuable aviation experience with, though with difficult working conditions many seem to move over to bmibaby, Menzies (a growing company, though apparently clinging desperately onto the TCX contract) or try a job elsewhere.
I've noticed there isn't really much standardisation within the company in terms of branding though. Everybody refers to the company as "Servisair" with uniforms, ground equipment and desks in a variety of "Servisair" "Servisair Globeground" and "Penauille Servisair" logos and liveries.
