Ruby Airport — Ruby, United States

RBY denotes Ruby Airport, a remote gravel airstrip serving the small community of Ruby, Alaska, located along the Yukon River in the state's interior. With no road access, Ruby depends entirely on aviation for passenger transport, mail, and cargo, making RBY a critical lifeline rather than a discretionary travel option. Small bush carriers operating out of Fairbanks or Galena provide scheduled flights to RBY using small fixed-wing aircraft suited to the unpaved runway and challenging Alaskan weather. The airport reflects the broader pattern across rural Alaska where tiny airstrips like RBY are essential infrastructure for isolated Native villages.
