Teeside is only 50 miles from Newcastle Airport (approx. 1 hour by road) Wouldn't time and money better be spent improving links to Newcastle, along with a strong campaign to attract more services to the North East Region as a whole. In comparison it takes about the same commuting time from Central London to Heathrow! I'm sure the whole N.E. Region would benefit from Airport Express Rail & Coach links, and improvements to A1/A696/ Airport road junctions, with more Air routes serving a wider catchment area from Newcastle.
Thoughts!
