The RDA caused alarm on Teeside when its draft economic strategy document recommended Newcastle airport become the main centre in the north-east for passenger travel.
Mo Mowlam, MP for Redcar, met John Bridge, One NorthEast's chairman, to discuss the document.
Keith Legg, Ms Mowlam's constituency assistant, said: 'She told John Bridge she did not like the language of the document. What she wants is a level playing field where one airport will not be pushed against the other.'
Newcastle, with three million passengers a year, currently has four times Teeside's throughput.
