Scottie Dog: FR will grow because the Sales Director, Tim McDermott, plans to slash the off peak charges from next April.
He's also increasing the peak charges a bit but the overall charges total will go down. It's a classic strategy to increase demand by reducing costs. A good idea given that most of the airport is under-utilised at off peak times, so it's money for old rope as most of the airport's cost is in the fixed assets (concrete, bricks and mortar) anyway so might as well be earning a few pence rather than sit idle, costing the same, and earning nothing.
Watch out for Tim. I tip him as the next MD of MA or CX of the MA Group. Can't do a worse job than the current bumbler anyway.
The masterplan will not reveal a 3rd runway or 4th terminal IMHO. I predict it will reveal massive expansion of the three existing terminals, more apron to east and west, and assume much better use of the off peak hours.
