I may be in the minority but having seen the options I actually think Opt 2 is the better.
Yes it means obtaining land from Mid Beds( not easy) using green belt land ( def not easy) and heritage problems (someries)
But they could build it without all the problems associated with Wigmore , the tip , etc
Build a new road link to the south and a second line on the DART. most of this could be built without impeding on the current traffic flow into the Airport.Similar to how STN got their terminal built.
Ok I know it's not going to happen but financially it is viable in comparison to how much it will cost for the North Option.
Regarding the airport operation of having a terminal north and south of the runway, maybe somebody from ATC would like to comment on the pitfalls, if any.
The way it is at LTN at the moment give Easy one terminal and Wizz/ Blueair/Ryanair the other one. Sorted!!
