Costco Wholesale flies to Washington the week tariff refunds hang in court

Costco Wholesale flew from Lagniappe STOL Field in South Carolina to Washington Dulles on June 18, 2026, aboard its Gulfstream G280 (tail N84CW). The short, 57-minute hop suggests a business trip rather than a routine repositioning.

The same week, Costco is navigating a high-profile tariff dispute. As covered by Yahoo Finance, CEO Ron Vachris confirmed on the May 28 earnings call that the company has begun submitting refund claims with U.S. Customs and Border Protection, following a Supreme Court decision that invalidated certain import levies. But the return process is complicated by a lawsuit filed against Costco regarding how refunds are distributed, per the same call. Washington is the natural venue for meetings with regulators and legal teams.

Costco has been a frequent visitor to Dulles lately: its G280 landed there on June 14 and again on June 12, part of a pattern of short-haul trips around the Eastern Seaboard that align with its steady growth in membership and record fuel volumes.
