Great Lakes Airlines is flying with a smaller number of passengers on flights in and out of South Dakota's capital city to try to reduce flight disruptions that have plagued Pierre in recent months.
Pierre Airport Manager Mike Isaacs says Great Lakes flights to Denver and Minneapolis are still on the same 19-passenger aircraft but are only carrying up to nine passengers per flight.
Delayed and canceled flights have been a problem in Pierre since late last year. Great Lakes officials have said the reason is new federal rules requiring more flying hours for pilots of the 19-passenger planes.
Isaacs says the reduction is temporary. He says the reliability of flights is more important now than the number of available seats.
