if Newcastle management had any nous...which I'm sure they haven't....they could offer eastern and klm an offer they couldn't refuse...free landing fees for 2 years??? For any flights transferred..."
Not 100% sure, but I believe this sort of action would be against Competition Law i.e. where 2 or more companies exchange data, pricing, contract info etc... to affect the market.
Penalties are quite substantial if found guilty (up to 10% of turnover I think) Maybe someone with legal qualifications can enlighten.
