ATC can see what we put in our MCP altitude box!
When flying over Europe and cleared to a flight level, we read back the cleared level but put the wrong flight level in, (the next higher, what I had expected and the planned level.) long before getting close ATC called and asked us to confirm assigned flight level. So, they could tell we put the wrong number in the box.
Maybe our aircraft are different.
and by the way, we have been putting a cabin crew in the flightdeck whenever a pilot leaves for years.
