The rail station is due to open in December and I believe they have hopes that this will entice at least one airline to SEN, hopefully from Spring 2010. Aer Arann have been mentioned but in the current economic climate it's anybody's guess. With trains every 20 minutes throughout the day it should make SEN-Central London journey times at least as good as for LTN and STN.
The Ramada hotel is due to start construction later this year, with the new terminal expected to open in 2011. Both of these projects already have planning consent. They have also been talking about a new control tower being built this year adjacent to the fuel farm, but seem to be treading water on that project at the moment.
Phase 2 of the re-development includes a 200m runway extension to give a useable runway length of 1,799m with an ILS being added on 06. That should enable A319/E195 operations to Med destinations to commence and it is hoped that it will be completed by late 2011.
