Hay River / Merlyn Carter Airport — Hay River, Canada

YHY is the IATA code for Hay River / Merlyn Carter Airport, serving the town of Hay River in the Northwest Territories, Canada. Positioned near the southern shore of Great Slave Lake, the airport functions as a vital transportation link for a remote northern community where road access can be limited seasonally. Hay River supports scheduled passenger flights, cargo movements, and charter operations that connect residents to larger centers such as Yellowknife. The facility also plays a role in supporting resource industries and emergency medical evacuations across the region. Given the harsh subarctic climate, the airport is equipped to handle winter operations, making YHY an essential piece of infrastructure for the surrounding communities.
