Wonder how Ryan Air etc would cope if a full complement of pax on one of their 737's got on with a carry on suitcase each, would be absolute bedlam
I have seen this happen. Excess cabin baggage is taken down the steps and put in the baggage hold. It is waiting for the pax when they disembark, along with the baby buggies etc.
This does not stop the pax who have their baggage removed from complaining though. The common theme is "I was on before him so I want my bag with me" or " there is stuff in there I need during the flight".
