Is LEEDS APPROACH the only person here who actually believes there is a need for another commercial airport in this area?
Whilst LBA is undoubtedly one of the most difficult airports I have ever had to get to by road (along with BRS!) there is already DSA serving South Yorkshire / North Notts', and a much bigger fish, in EMA, which is only around 1 hour south of Sheffield given a fairly clear run down the M1.
The UK needs fewer, not yet more nonviable commercial airports. I seriously wonder why banks and other institutions seem keen to support these kinds of ventures. Airports handling less than 1m passengers p.a. must be marginal, from a financial perspective - unless they have other revenue streams such as cargo operations to fall back on.
