Lufthansa used to self handle at some stations (LHR etc). They then split the company up to retain profitablity and so Lufthansa Ground Services was born. In time this changed to GlobeGround.
Servisair was a separate entity which was well established in Manchester, Luton etc. They bought GlobeGround and hence it became Servisair GlobeGround. Now all Servisair people are supposed to be under one umbrella!
Simple?...hold on...Last year (or was it early this year) Penauille Polyservices who are non aviation related bought Servisair GlobeGround. Penauille are a French company specialising in waste management. They also own ICS the cleaning company used by some airlines.
So..now...we have Penauille Servisair and the GlobeGround part has been dropped.
Penauille Servisair now have their own dedicated cargo facility at Heathrow handling EK, SQ and UL cargo operations. A further twist....rumours have it that there is a new owner..some scrap metal company...
