The LCCs in Europe do some pretty long sectors. UK-Morocco (Ryanair), flights into Istanbul, Athens. These are 3-4 hour sectors at least!!
The European LCC market is interesting - you have everything from Ryanair's glorified bus service (not even glorified!) to some LCCs with assigned seating, free meals, FF program etc etc. As an example I was most impressed with Air Berlin and Morocco's Atlas Blue even gave me a full HOT meal on a flight between Brussels and Morocco despite paying about only 30 euros for a 3 hour+ sector!
