Considering should Tees Valley Airport close, which seems more & more likely (Especially for passenger services), wouldn't the best alternative be to provide better, faster and more comfortable surface links to Newcastle Airport via Coach & Rail. In particular from the East of the region; Midllesbrough & Stockton are not served well,(in terms of Comfort & Speed) although the cost in providing better rail rolling stock, interlining with the Metro to Newcastle Airport and regular Direct Airport Coach services, would be far less than those costs associated in attempting recue of a failing Tees Airport. There may be further benefits in this approach, attracting more services to the North East's wider region, with a larger catchment population. Thoughts!
