The rain cover for my pack is held around the container part of the pack with elastic, and brushing against it can easily pull it off the pack. Getting the shoulder straps of the pack caught on machinery as it moves the baggage system is the greatest element of risk to the pack, and the rain cover will do nothing to protect them. The heavy weight plastic of certain oversized bags will completely envelope the pack, containing all straps and keeping them from getting caught in machinery.
