Well, Continental apparently will sell you as many seats as you want. When I flew EWR-HKG Mar 9, there was a guy sprawled out sleeping on all three seats in the middle row. It was a crowded flight and when people complained, the FA checked and then we noticed that he had all three boarding passes placed in the seatbacks of the row in front of him so people wouldn't bother him. The FA told us that he had said that he had to go to work immediately on arrival and wanted to ensure some sleep.
