I have an upcoming flight on a 2-class 777 which appears to be oversold already a few weeks out (zeroed out in both J and Y). Does anyone know if they oversell both cabins and if a IDB might come into play? As of now there are only 2 J seats unselected. Would they really oversell J on a 2-class as I don't believe they normally oversell F on a 3-class.
