However there will ALWAYS be a demand for people wanting to fly direct into the center of the City.
Er....well Glasgow failed three times before it was reinstated for a fourth time. Dropped by Air UK, ScotAirways and then BA before BA returned when they axed a few GLA-LHR slots.
Belfast was dropped recently by ScotAirways as the traffic didn't materialise as a lot of Befast traffic is connecting on and there's none of that at LCY. The leisure market is best served on a cheaper option than a Do328.
Newcastle was uneconomic on a Jetstream 41 for Eastern as the landing rates discount ran out and market rates killed the yield.
Manchester has just been axed by VLM, following Liverpool last year.
Therefore, unless this operation is seriously capitalised to take losses for a long period, I doubt they'll last six months as the demand for air travel from the square mile to Middlesborough and the Tees Valley isn't that huge. They will have to charge real money to make this work and somehow I don't see that happening.
Ryanair would surely run STN-MME just for the summer to kill them off.
