River Joint,
I have endured your liquid fueled replies for some time,it's about time you realised that SOU has been lacking in progressive management and development for some time.There is no certainly that any LCC operators will come to the airport even after any runway developments. Notams show there is no stand developments contrary to your post. Planning permission and any adjustments in airport opening times have yet to be discussed. BOU and SOU can exist perfectly in future operations,but especialy with the Brexit loming things might change that effect operations.
Certainly without runway extensions SOU future is in no way certain. BOU operations could serge upwards given better transport connections,they do have two essential asserts over SOU ,and that is a 7000ft runway,and plenty of space for stand development,oh and can stay open for sustainable operations.
So take stock of realistic possibilities for both airport's and take note of the silly little details that could have signigfcant reprocusions on the airport's development.
