You guys are totally getting carried away with yourselves, in the last page or so it is being peoposed, from SOU:
KLM to Amsterdam
Air France to CDG
Aer Fungus to Dublin
SAS to Copenhagen
Luxair to Luxembourg
Swiss to Zurich
BMI to Copenhagen, Lyon, Hamburg and Berlin
Lufthansa to Frankfurt, Munich, Dusseldorf, Hamburg and Stuttgart
Crikey guys, you're asking for more services and operators than even England's 2nd largest city of Birmingham has yet SOU is a regional 'town' airport!
To comment on the above, KLM to AMS or AF to CDG, one or the other but not both from 'KLM Air France'.
Dublin as an 'end of the road route' fair enough but a LCC route.
SAS to CPH, business travellers want onward connections on the same airline (for price) and SAS's route network leaves a lot to be desired!
Luxair to LUX, in UK Luxair only serve London, they tried MAN previously, is it seriously being suggested that their 2nd UK destination become SOU before MAN, BHX, Scotland etc?
Swiss, and what a lovely service they provide, in England, they only serve LON, MAN and BHX, next should be SOU?
BMI to CPH, Lyon, HAM and Berlin, CPH, HAM and Berlin already provided, by suggestions, via SAS, LH and Lyon via a connection from umpteen airports already mentioned.
Lufthansa to umpteen points in Germany? Come off it, if AF or KL are already operating, providing the worldwide connections, including connections to these German airports, then why would LH be interested however it only takes one LH route from SOU to provide connections to all over Germany and indeed the world.
Get real guys, SOU is not a major gateway airport and never will be, just as an example Cardiff, on the same level, is only served (for international connections) by KLM and it works very well for travelling the world, you seem to be expecting some 7 such operators and it ain't ever going to happen!
