You have missed the point. Stansted is operating at around half capacity while Luton is almost at capacity.
Agree with your comment about the town. Bit unfair about the airport which due to massive demand is having the nearly double capacity while Stansted is struggling to hang on to its passengers.
Think you miss understand my points...
Stansted circa 18,000,000 passengers in 2011
Luton circa 9,500,000 passengers in 2011
Yes Stansted has seen a decline since it's 2007 triumph, something that MAG intends to address.
Luton is seeing an increase in passenger numbers but, despite this
Stansted still has double the number of passengers that Luton has.
Stansted has the infrastructure in place and is in a better position now to expand as Luton will get left behind.
Maybe it's time to put this rather tedious debate to bed, once and for all.
