Jersey Airport — St. Peter, Jersey

JER is the code for Jersey Airport, located near St. Peter on the island of Jersey, the largest of the Channel Islands and a British Crown Dependency. JER serves as the primary air gateway for the island, connecting Jersey to destinations across the United Kingdom, mainland Europe, and beyond, supporting both tourism and Jersey's significant finance industry. The airport handles a healthy mix of scheduled airline service and private aviation, given Jersey's status as a wealthy offshore financial center. Jersey's compact size and lack of rail links make JER especially important, and the airport has invested in runway and terminal improvements over the years to accommodate steady passenger demand from both leisure travelers and business commuters.
