yep...my firsthand experience in recent memory, pmUA DEN-LHR-DEN, in it's brief existence, was generally always full. BA's flight didn't suffer much, either.

First, they didn't operate it in winter (ski season), conceding that tourist traffic to BA,then it just died. As a twice monthly TATL traveler in those days, it was a SWU (GPU) users dream.

Other examples abound, and Greece's current politco-economic situation is certainly not helping, but full doesn't always equal profitable.
