Traveler Information 

(406) 433-3273
Sidney-Richland Airport encourages you to arrive one hour before your scheduled flight.
While we are a small airport, flying on Cape Air’s Cessna 402 requires a unique check-in process where passengers are asked for their weight, all bags must be weighed and then a weight and balance is calculated by the pilots. The aircraft is then loaded according to the weight and balance calculations. Passengers will also need to be screened by TSA before boarding the aircraft.
Due to this process arriving one hour before your scheduled flight is strongly encouraged.
