Huge misunderstanding here, all the article is saying is that Eastern have bases at those airports.
I don't think any of those routes would EVER work for eastern, unless an existing flybe route that needed a reduction in capacity like Southampton-Paris
Also, Eastern are based at Orly, Flybe and Air France at Charles de Gaulle
dtvmovements really clutching at straws here I'm afraid. It is a slightly confusing article, but I struggle to see how anyone could think that was an announcement of a Flybe/Eastern Teesside-Paris flight. Who would pay £400+ for that when you can spend half the money on KLM? And realistically Paris isn't that huge from a lot of UK markets... It wouldn't work. London, Dublin, Belfast, Spain, Canaries, Balearics, Greece, Bulgaria, Portugal... Yes. Paris, not so much
