RCA was set up by BB and eventually sold to the company that bought Exeter off BB. Im led to believe by someone in the know that all the licences and key contracts are in the name of / contracted to RCA, airport director transferred to RCA as did the SATCO so when the operating company went out of business it had limited impact on the airport.
I think most people would come to similar opinion of the situation and motives if they reviewed the facts that are in the public domain over the last 4 - 5 years. From around 2010 when airport staff were put at the risk of redundancy due to a dispute with Jet2 and the airports desire to renogiate terms, subsequent court cases the airport lost with Jet2 and now the closure and reopening minus commercial operations.
Personally I say good luck, if Jet2 were making large profits while aware of the imbalance in the relationship they can have no complaint when the golden goose dies through neglect. No organisation however big can continue to sustain such large losses year on year with no realistic prospect of the situation turning round.
Unfortunately its the people who can least afford to lose their jobs who ultimately suffer, the staff at the bottom on low wages and often zero hour contracts.
Hopefully they can now build a sustainable business based on commercially viable contracts.
