easyflyer83. As mentioned in post 2, the requirement is (or was) 1 cabin crew per 50 seats, not per 50 pax. Years ago I departed base with a 98 seat aircraft and 2 cabin crew. We had a tech problem and returned. The replacement aircraft (same type, same number of pax) was a 110 seater. We had to delay while another cabin member was called in off standby.
