> I wonder if a plane was packed with all first class seats how expensive the tickets would be. It's pretty normal to have all lie-flat business/first-class flights between major business centres such as New York and London. You wouldn't know about them unless you were booking a first-class ticket in the first place, so they're not very visible. I think the prices are the same as normal? Otherwise nobody would use them, of course.
