cant see why the real lo-cos dont want to go there
Given that rather more "lo-cost" operators serve Ringway than serve Liverpool, I presume that you're talking about easyJet when you say "real lo-cos"?
In what way are Jet2, Air Berlin, Hapag Lloyd Express, bmiBaby, Ryanair and MyTravel Lite unreal?
OK - maybe not the last one.....
Oh, and I suppose we have to include the "no-frills" scheduled services by Monarch, too.
