Can't think of many low cost going to LCA, FCL,POP,Izmir,TLV,Ibiza, (long haul to Cuba, caribbeans).... let me know, specially since many of charter airlines are operating things like 757/767/A320/A330, when in comparison the low cost flyw 737, 146 (EZ,FR,Buzz,...)
I was more under the impression that the low cost were concentrating on high revenue routes like (from the UK) NCE, BCN,GVA,LPL,HAN,... or odd routes like POI and stuffs.
