a) Does Warsaw even need a second airport?
Modlin will be dedicated to low cost airlines, as a frequent flyer when spending my own money I select on price, so in my opinion competition is good for the consumer.
b) In what way is it a leg up?
Modlin should assist in bringing down prices for travelers, provide more low cost routes, as well as taking some traffic away from Okęcie.
c) Real second airports are places such as Gatwick.
I could not even begin to compare Warsaw to London.
Maybe Manchester or Birmingham in size of population.
