Re: NATS at City, an interesting aspect of the tender was:
Belfast City Airport (BCA) is seeking a provider of Air Traffic Control (ATC) services. The successful bidder will utilise staff that are currently directly employed by BCA in this service provision. It is anticipated that TUPE (being the Transfer of Undertakings (Protection of Employment) Regualtions) will apply.
which would suggest that consolidation of operation at International's site would be difficult.
