Cork routes
The shortage of stands at Cork is chronic but that shouldn't stop Ryanair or Easyjet from expanding. There are times during the morning and early evening when there are up to eight stands free for several hours.
Cork management have traditionally been cautious in the kind of concessions they give to airlines but they'll probably have to be a bit more adventurous if they want to reach their 5 million per annum target for the new terminal.
An expansion by FR on UK routes would not greatly dilute their Shannon Traffic though it would probably get rid of many of the smaller regional operators such as Loganair, BMI Regional, Air Wales and Aer Arann.
However the first two listed have made no effort to grow the traffic on their Cork Routes so I don't see why management at Cork will be over concerned about them.
