Customers and suppliers

Who buys from LUV and who it buys from, as the companies report it.

Customerswho buys

None disclosed.

Supplierswho it buys from

A company has to disclose every customer behind 10% or more of its revenue. Each share comes from the latest annual report of the company that states it and shows on both companies’ pages; LUV’s own figures are from its FY2025 10-K. Smaller customers and suppliers go unreported. A link without a share is named in one of the two companies’ annual reports, without a figure.
