Seguro have an excellent track record at PIK. They are Manchester based company who have built up a strong local following for quality hoildays at good prices. They may not generate dozens of weekly flights but they are more likely to be there in 5 years than some other companies.
As far as the Manston website is concerned I suspect they have employed the same company who redesigned the PIK one along with the slogan " Pure Dead Brilliant" It caused a lot of chat amongst the traditionalists in Scotland who were shocked. The overall look of their airport makeover was pretty snazzy.
