Embodiments relate to adjusting cabin pressure based on ambient conditions to achieve a target aircraft inflow. An aspect includes receiving a number of occupants on an aircraft. The ambient conditions on the aircraft are monitored and an occupant threshold limit is determined for the aircraft based on the ambient conditions. If it is determined that the number of occupants exceeds the occupant threshold limit, the cabin pressure is reduced in the aircraft according to embodiments. The cabin pressure in the aircraft is reset in response to the occupant threshold limit being increased due to changing ambient conditions.
