Toontartcart !
In my experiences of Groundstar/Northeast Aviation at NCL and the sister-company (previously Northwest)at MAN I can honestly vouch for the staff at both bases, who do an excellent job with minimal staffing levels.
Their operation which serves BA and its subsiduaries to a high standard is geared up for prompt turn-arounds in a helpful and professional manner. Not wanting to start a slanging match by any means, but believe me Servisair quite often leaves a lot to be desired in it's level of service at some airfields whilst at the same time achieving good results at others!
