RTG - Things are not looking too good for many other companies not just Servisair!
In fact they have several new contracts too. Sometimes, the loss of a contract although it may seem like a huge loss can in fact help in a twisted way. If these contracts were negotiated on unfavourable or barely break-even terms then cutting these out "could" improve the books slightly.
Likewise, Aviance/Menzies et.al. have their own issues too. This is a common problem for ALL ground handling companies.
TUPE can also cause problems for the new handling company. Significantly higher employee costs than those on their on contracts will push up their costs. While they may have secured low contract prices--margins would be greatly reduced.
