Seattle Tacoma International Airport (SEA) is grappling with significant fuel supply issues that are beginning to affect passengers. This comes at an inopportune time, right before the bustling Thanksgiving travel period.
The Olympic Pipeline, which supplies fuel to SeaTac Airport, has been experiencing significant disruptions. Last week, the pipeline was shut down due to a discovered leak. Although it was temporarily restored, another leak was identified soon after, leading to another halt in operations. BP Pipelines North America, which manages the pipeline, has announced that there is currently no timeline for when service will be restored. In light of these challenges, Washington Governor Bob Ferguson issued an emergency proclamation, highlighting the potential for serious impacts at the state’s largest airport if repairs are not completed by Saturday evening. However, the likelihood of a swift resolution seems slim, as new leak issues are emerging and parts of the pipeline are undergoing excavation for visual inspection.
In response to the fuel shortage, truck deliveries to SeaTac Airport have increased. However, these efforts struggle to match the usual volume provided by the pipeline.
Despite the ongoing situation, flights at SeaTac had been mostly operating smoothly, largely due to the airport’s fuel reserves. Nevertheless, the first few flights are beginning to experience disruptions, particularly on long-haul routes. Taiwanese carriers EVA Air and Starlux Airlines have altered their services to incorporate refueling stops. EVA Air is routing flights through Anchorage, while Starlux Airlines is making stops in Portland.
Alaska Airlines and Delta Air Lines, the two largest carriers operating at the airport, have not yet reported disruptions but are preparing for potential impacts. An Alaska Airlines spokesperson stated that the airline is implementing contingency plans, which include fuel management strategies such as tankering fuel on inbound flights to Seattle and evaluating technical stop options on certain routes to save fuel. Delta Air Lines has also echoed similar assessments, advising customers to check the status of their flights ahead of their trips to the airport while they work with fuel supply partners to minimize disruptions.
Given the current trajectory of events, it appears that operations at SeaTac may soon face widespread impacts, particularly for long-haul flights where fuel management becomes increasingly challenging. Travelers are advised to stay updated on their flight statuses as the situation continues to evolve.
In summary, the ongoing issues with the Olympic Pipeline have resulted in a serious fuel shortage at SeaTac Airport. While the repercussions have thus far been limited, they are expected to escalate, leading to more airlines scheduling refueling stops as they adapt to the crisis.
