I don't think anybody was suggesting that they move ALL operations.
Shortly, STN will reach it's current maximum capacity of 25m pax per annum. If FR, EZY or AB are wanting to expand further from the airport, they may have to move some to of their servies.
Personally, I don't see what is wrong with LTN, but if Cambridge can offer the goods, I am sure EZY etc would take it.
Maybe FR will move it's domestic services such as BLK, NQY, PIK and Londonderry to the airport. This would free up alto of slots at STN, as BLK flies (x2), NQY (X1), PIK (x5) and Londonderry (x2).
IF FR were to go into long haul, then 10 turnaround slots would be great for starters!
Base two a/c, with the PIK aircraft operating the PIK flights.
Would you have ever guessed this at Blackpool Airport:
*Final call for Ryaniar flight 2757 to Cambridge.*
Especially with a 738!!!!!
Anyway, will probably never happen!
