The Olympic Pipeline delivering jet fuel to Seattle-Tacoma International (SEA) was partially restarted on November 25, addressing the fuel shortage caused by a leak discovered on November 11, which led to its shutdown. BP, the pipeline owner, deemed it safe to restart one of its two pipes while repairs are underway on the other. This development has allowed airlines to adapt their operations amid ongoing supply issues.
Alaska Airlines and Delta Air Lines, the primary carriers at SEA, have previously implemented fuel-saving measures, including making additional fuel stops along some routes. Meanwhile, Washington Governor Bob Ferguson issued an emergency declaration to waive restrictions on trucks carrying jet fuel, aiming to augment fuel supplies to the airport. An inspection on November 24 found no indications of a leak in the smaller pipeline, enabling BP to restart that pipe, but the larger pipeline remains shut down due to a confirmed leak. Repair plans for the affected pipeline are in progress.
Supply Management and Airline Strategies
Alaska Airlines reported that the recent fuel stops—around 12 daily flights—are no longer necessary, though it will continue tankering fuel on inbound flights to SEA. Trucks will also keep bringing additional fuel to ensure smooth operations. The airline confirmed that operations are returning to normal without expected further impacts. U.S. Senator Maria Cantwell emphasized that SEA relies on over 1,000 daily flights, which require reliable fuel access.
“Despite the emergency order suspending truck hours restrictions, only about half of the airport’s fuel needs are currently met by deliveries, with approximately 90 trucks arriving every 24 hours,” said officials managing the situation.
Airlines are managing this shortage through fuel management strategies, and carriers like Delta have warned that schedule adjustments might still be necessary if the pipeline remains closed. The situation remains dynamic as repairs and assessments continue.
